- draw flowchart about User and consultant
administration

Answers

Answer 1

User and consultant administration is an important aspect of system analysis. The process of system analysis involves the examination of how a system works, including its user interface, hardware, software, and other components. In the context of user and consultant administration, system analysis seeks to identify the roles and responsibilities of these two groups within a system, as well as the workflows and processes involved in managing them.



The process of user administration involves creating, managing, and deleting user accounts in a system. User accounts can be created for individuals, groups, or departments, and can be assigned specific permissions and privileges based on their role within the system. User administration also involves setting up authentication and access control mechanisms to ensure that only authorized users can access sensitive system resources.

On the other hand, consultant administration involves the management of external contractors or vendors who provide specialized expertise or services to the organization. Consultant administration includes tasks such as hiring, contract negotiation, and managing consultant work schedules and deliverables.

In order to understand the workflows involved in user and consultant administration, it is often useful to create flowcharts that map out the different steps involved in each process. A flowchart is a visual representation of a process that uses symbols and diagrams to illustrate the various steps and decision points involved. By creating flowcharts of user and consultant administration processes, system analysts can better understand how these processes work, identify potential bottlenecks or inefficiencies, and suggest improvements to streamline workflows and improve system performance.

To produce machine codes for a generic CNC mill by manually writing the program, you can use trigonometry and manual calculation. The CNC mill is used to cut, drill, or shape a variety of materials, including metal, wood, and plastic.

The CNC mill is controlled by a computer, which tells the mill how to move the cutting tool based on a set of instructions in the form of a program. There are several steps involved in manually writing a program for a CNC mill using trigonometry and manual calculation. Step 1: Determine the tool path The first step in writing a program for a CNC mill is to determine the tool path. The tool path is the path that the cutting tool will follow as it cuts the material. You can determine the tool path by drawing a sketch of the part and calculating the coordinates of each point on the part that the tool will touch. Step 2: Calculate the coordinates Once you have determined the tool path, you can calculate the coordinates of each point on the part that the tool will touch. This involves using trigonometry to calculate the X, Y, and Z coordinates of each point based on the tool path. Step 3: Write the program
Once you have calculated the coordinates of each point on the part, you can write the program. The program consists of a series of instructions that tell the CNC mill how to move the cutting tool. The instructions are written in a special language called G-code.

lease answer the following questions, showing all your working out and intermediate steps. a) (5 marks) For data, using 5 Hamming code parity bits determine the maximum number of data bits that can be

Answers

Hamming code is a type of error-correcting code that involves adding extra parity bits to data to detect and correct errors. The number of data bits that can be protected by Hamming code with a given number of parity bits can be calculated using the formula: 2^r >= m + r + 1, where r is the number of parity bits and m is the number of data bits.

For example, if we have 5 Hamming code parity bits, we can calculate the maximum number of data bits that can be protected as follows:[tex]2^5 >= m + 5 + 1[/tex]

Simplifying:32 >= m + 6m <= 26

Therefore, the maximum number of data bits that can be protected by 5 Hamming code parity bits is 26. This means that we can transmit a message consisting of up to 26 bits using 5 Hamming code parity bits to detect and correct errors.

Another way to look at this is to say that the number of data bits is the difference between the total number of bits and the number of parity bits. In this case, the total number of bits is the sum of the data bits and the parity bits, which is 26 + 5 = 31. Therefore, the number of data bits is 31 - 5 = 26.

Answers

A shift register is a type of circuit that stores binary data and shifts it left or right. A counter is a circuit that increments a binary number by one on each clock pulse. Here's how to construct a 6-bit shift register and a 4-bit binary ripple counter using D flip-flops and JK flip-flops, respectively.

Additionally, we'll create truth tables for each circuit. 1. 6-bit Shift Register with D Flip-Flops (Shift Right)The CD40174BC is a D flip-flop chip with six D-type flip-flops. The following diagram shows how to construct a 6-bit shift register using D flip-flops. A shift register with six flip-flops is required, thus  six CD40174BC D flip-flops are used. For data and clock, each flip-flop needs one input pin. The output of each flip-flop is connected to the input of the next flip-flop. The last output is taken out as a serial output.  A truth table for the 6-bit shift register with D flip-flops is given below:    2. 4-bit Binary Ripple Counter with JK Flip-Flops. The CD4027BE is a JK flip-flop chip with two J-K flip-flops. The following diagram shows how to construct a 4-bit binary ripple counter using JK flip-flops. The flip-flop sequence Q0 to Q3 is arranged in a binary order. This counter will count the pulses applied to the clock input. Since each J-K flip-flop needs a clock and J-K input, there are two input pins per flip-flop. The clock input of the first flip-flop is the clock input for the whole counter, and the J and K inputs of the flip-flop are connected to logical 1s to make it toggle on each clock pulse. The output of the first flip-flop (Q0) is linked to the clock input of the second flip-flop, and so on.  A truth table for the 4-bit binary ripple counter with JK flip-flops is given below:   These are the 6-bit shift register and 4-bit binary ripple counter with their respective truth tables.

(Please write plain code!!! Do not submit screenshot) Write instructions that set the Zero flag if the 32-bit value in EAX is even and clear the Zero flag if EAX is odd. Write a program to test the instructions.

Answers

The code sets the Zero flag if the 32-bit value in EAX is even and clears the Zero flag if EAX is odd.

What is the purpose of the code in x86 assembly language provided to test if the 32-bit value in EAX is even or odd and set/clear the Zero flag accordingly?

Code in x86 assembly language that sets the Zero flag if the 32-bit value in EAX is even, and clears the Zero flag if EAX is odd:

```assembly

section .text

   global _start

   

_start:

   mov eax, 42       ; Assign a test value to EAX (even)

   test eax, 1       ; Perform bitwise AND operation with 1

   jz even           ; Jump to 'even' label if Zero flag is set (EAX is even)

   

   ; EAX is odd, clear the Zero flag

   xor eax, eax      ; Set EAX to 0

   jmp done          ; Jump to 'done' label

   

even:

   ; EAX is even, set the Zero flag

   mov eax, 1        ; Set EAX to any non-zero value

   

done:

   ; End of program

   mov ebx, 0        ; Set exit status to 0

   mov eax, 1        ; Specify 'exit' system call number

   int 0x80          ; Call the kernel

```

This code sets the value of EAX to 42 as a test value (even). It then performs a bitwise AND operation with 1 using the `test` instruction. If the result is zero (Zero flag is set), it jumps to the 'even' label, indicating that EAX is even. In the 'even' section, EAX is set to a non-zero value to keep the Zero flag set. If the result is non-zero (Zero flag is not set), it jumps to the 'done' label, clearing the Zero flag by setting EAX to 0. Finally, the program exits with the appropriate exit status.

1 (b) Assume a program takes N seconds to execute running on a single processor. If the same program is executed in parallel using X processors, we expect its execution time to reduce to N/X seconds. However, this does not happen. Examine the reasons behind it.

Answers

When a program is executed in parallel using multiple processors, the expected reduction in execution time to N/X seconds may not be achieved due to various reasons such as overhead, communication and synchronization costs, and limited scalability. These factors can impact the efficiency and performance of parallel execution, resulting in suboptimal speedup.

The reasons behind the inability to achieve the expected reduction in execution time include:

1. Overhead: Parallel execution introduces additional overhead in terms of task distribution, synchronization, and data communication between processors. This overhead can reduce the overall speedup and offset the benefits of parallelism.

2. Communication and synchronization costs: When multiple processors work on different parts of a program, they may need to communicate and synchronize their actions. These operations incur time and resources, and if they become frequent or time-consuming, they can hinder the expected speedup.

3. Limited scalability: Some programs may not be inherently parallelizable or may have dependencies that limit the degree of parallelism. As the number of processors increases, the scalability of the program may diminish, resulting in diminishing returns in terms of reduced execution time.

To overcome these challenges and improve parallel execution efficiency, techniques such as workload balancing, minimizing communication overhead, and optimizing synchronization mechanisms can be employed. Performance profiling and analysis tools can also help identify and mitigate bottlenecks in parallel execution.

c. mAs and grid ratio.
d. focal spot size and patient thickness.

Answers

Factors affecting recorded detail include (b) radiographic grids and collimation, and (d) focal spot size and patient thickness.

Recorded detail refers to the level of sharpness and clarity of structures recorded on a radiographic image. Several factors influence the level of recorded detail in radiography:

b. Radiographic grids and collimation: The use of radiographic grids and proper collimation plays a significant role in improving recorded detail. Grids are used to absorb scatter radiation, which can degrade image quality and reduce recorded detail. Collimation helps to limit the X-ray beam to the area of interest, reducing scatter radiation and improving image sharpness.

d. Focal spot size and patient thickness: The size of the focal spot on the X-ray tube and the thickness of the patient's body part being imaged also impact recorded detail. A smaller focal spot size allows for better spatial resolution and increased sharpness of the image. Thicker body parts can attenuate the X-ray beam, leading to increased scatter radiation and reduced recorded detail.

Other factors that can affect recorded detail but are not mentioned in the options include motion blur (caused by patient movement or uncontrolled motion during exposure) and image receptor characteristics (such as pixel size and detector resolution).

Recorded detail in radiographic images is influenced by various factors. Among the given options, radiographic grids and collimation (b) and focal spot size and patient thickness (d) are significant contributors to the level of recorded detail. Proper use of grids, appropriate collimation, optimal focal spot size, and consideration of patient thickness are essential for achieving high-quality radiographic images with optimal recorded detail.

n a ____ network model, the operating system of each computer on the network is responsible for controlling access to its resources without centralized control.

Answers

In a peer-to-peer network model, the operating system of each computer on the network is responsible for controlling access to its resources without centralized control.

In a peer-to-peer network model, there is no centralized server or authority governing the network. Instead, each computer, or peer, operates as both a client and a server, allowing for direct communication and resource sharing between peers. The operating system of each computer is responsible for managing its own resources and controlling access to them.

In this model, when a peer wants to access a resource on another peer's computer, it sends a request directly to that peer. The operating system of the receiving peer then determines whether to grant or deny access based on its configured permissions and security settings. This decentralized approach allows for greater flexibility and scalability in the network, as there is no single point of failure or bottleneck.

By distributing the responsibility of resource management across the network, peer-to-peer models can be more resilient and efficient compared to centralized models. Each computer operates autonomously, making independent decisions about resource access, which reduces the reliance on a single point of control. However, it is important to note that the absence of centralized control can also introduce challenges in terms of security and coordination.

i) The transition image for the Turing machine that computes the function f(101m) = 1m-n involves a step-by-step process to subtract the number of 1s in the input from the total number of digits in the input.

ii) The transition image for the Turing machine that computes the function f(1) = 1n² involves a straightforward process to square the value of n.

i) To compute the function f(101m) = 1m-n, the Turing machine's transition image would include steps to count the number of 1s in the input string and then subtract that count from the total number of digits in the input. The machine would traverse the input tape, marking each 1 encountered, and increment a counter. Once the end of the input is reached, the machine would move to a separate state to traverse the tape again, counting the total number of digits. Afterward, the machine would subtract the count of 1s from the count of total digits, and the result would be written on the output tape.

ii) For the function f(1) = 1n², the Turing machine's transition image would involve a simple process of squaring the value of n. The machine would read the input tape, which contains a single 1, and then move to a separate state to perform the squaring operation. This can be achieved by copying the input symbol onto a separate tape and then traversing it twice, effectively concatenating the input string with itself. The result, n², would then be written on the output tape.

Understanding the concept of Turing machines and their ability to perform calculations provides valuable insights into the theory of computation and the foundations of computer science.

List and explain any FIVE of the advantages of database approach over the traditional flat file approach in data management.

Answers

The database approach offers several advantages over the traditional flat file approach in data management. Here are five key advantages:

1. **Data Consistency**: In a database, data is stored in a structured and organized manner, ensuring consistency throughout the system. Unlike flat files, where redundant data can lead to inconsistencies, databases enforce integrity constraints, such as primary keys and referential integrity, to maintain data accuracy and reliability.

2. **Data Integrity and Security**: Databases provide robust mechanisms to ensure data integrity and security. Access controls can be implemented to restrict unauthorized access and protect sensitive information. Additionally, databases offer features like transactions and logging, which help maintain data integrity by ensuring that operations are either completed in entirety or rolled back in case of failures or errors.

3. **Data Sharing and Collaboration**: Databases facilitate data sharing and collaboration among multiple users and applications. Unlike flat files that are typically accessed by a single user at a time, databases support concurrent access and allow multiple users to access and modify the data simultaneously. This enables real-time data updates, enhances productivity, and promotes collaboration within an organization.

4. **Data Independence**: Databases provide a layer of abstraction between the physical storage of data and the way it is accessed by users and applications. This allows for data independence, meaning that changes to the database structure or organization can be made without affecting the applications that use the data. This flexibility enables easier maintenance, scalability, and adaptability to evolving business needs.

5. **Data Query and Analysis**: Databases offer powerful query languages, such as SQL (Structured Query Language), that enable users to retrieve, manipulate, and analyze data in a structured manner. These query languages provide a standardized and efficient way to extract relevant information from large datasets, perform complex calculations, generate reports, and gain valuable insights. Such capabilities are not easily achievable with flat file systems, where data retrieval and analysis often require custom programming or manual processing.

In summary, the database approach provides advantages such as data consistency, integrity, security, sharing, collaboration, independence, and efficient query and analysis capabilities, making it a preferred choice for effective data management compared to the traditional flat file approach.

used primarily in the united states for electricity generation:

Answers

Coal is the primary fuel used in the United States for electricity generation. Coal-fired power plants produce approximately 50% of the electricity generated in the United States.

The process of creating electrical energy from other energy sources is referred to as electricity generation. The two basic principles for producing electricity are electromagnetism and the photoelectric effect. Electricity is produced from coal using steam turbines. Coal is burned in boilers, producing steam that drives turbines, which then turn generators that produce electricity.

Although the entire process has some environmental consequences, coal-fired power plants have been built to minimize them by reducing greenhouse gas emissions and utilizing more efficient technology that generates more electricity using less coal.

Mapping Cardinality Constraints (8') a. For a binary relationship set, commonly there are four types of mapping cardinality. Please list out these four types. (4') b. How to express these four types of mapping cardinality in the E-R diagram? Please use the E-R diagrams to illustrate. (4', Hint: draw four E-R diagrams, using the principal style you have learned in this course)

Answers

The four types of mapping cardinality for a binary relationship set are one-to-one (1:1), one-to-many (1:N), many-to-one (N:1), and many-to-many (N:M). These types can be expressed in an Entity-Relationship (E-R) diagram using different notations and cardinality indicators.

1. One-to-One (1:1):

In a one-to-one relationship, each entity in the first entity set is associated with at most one entity in the second entity set, and vice versa. In an E-R diagram, this can be represented by drawing a straight line connecting the two entities and placing the cardinality indicator "1" on both ends of the line.

2. One-to-Many (1:N):

In a one-to-many relationship, each entity in the first entity set can be associated with multiple entities in the second entity set, but each entity in the second entity set can be associated with at most one entity in the first entity set. In an E-R diagram, this can be represented by drawing a straight line from the first entity to the second entity and placing the cardinality indicator "1" on the side of the first entity and "N" on the side of the second entity.

3. Many-to-One (N:1):

In a many-to-one relationship, each entity in the first entity set can be associated with at most one entity in the second entity set, but each entity in the second entity set can be associated with multiple entities in the first entity set. In an E-R diagram, this can be represented by drawing a straight line from the second entity to the first entity and placing the cardinality indicator "N" on the side of the first entity and "1" on the side of the second entity.

4. Many-to-Many (N:M):

In a many-to-many relationship, each entity in the first entity set can be associated with multiple entities in the second entity set, and vice versa. In an E-R diagram, this can be represented by drawing a line connecting the two entities and placing the cardinality indicator "N" on both ends of the line.

By using these notations and cardinality indicators in an E-R diagram, the different types of mapping cardinality can be visually represented, providing a clear understanding of the relationships between entities in a database system.

Vito wants to minimize the total distance to all of them and has blackmailed you to write a program that solves his problem. The input contains several test cases.

The first line has the number of test cases.

Each test case has a single line with the number of relatives n (1 ≤ n ≤ 500) and their street addresses.

The street addresses are integers between 0 and 30000. Vito’s house is at position x = street[n/2] if n is odd. If n is even, then there are two possible positions for Vito’s house, and we print the smallest one.

The solution to this problem involves finding the median street address and calculating the total distance to all other relatives.

To find the median, we sort the street addresses in ascending order and take the middle element. If there are an even number of relatives, there are two possible median addresses, so we take the smallest one.

Once we have the median, we calculate the total distance by adding the distance from the median to each of the other points. We then print the total distance.

(a) List transport layer services. [3] (b) Write down the role of IP addresses and port numbers in selecting the final destination of data.

Answers

(a) Transport layer services are services provided by the Transport Layer of the OSI Model to ensure reliable data communication between applications running on networked hosts.

The three most common Transport layer services are given below:

Reliable data transfer: Data that is sent from one device to another is subject to loss, duplication, and corruption. To ensure that the data arrives at its intended destination, the Transport layer ensures reliable data transfer.

Service Access Points: The Transport layer provides a service access point to enable applications to interact with the Transport layer, which in turn interacts with the network layer.

Connection-oriented services: The Transport layer establishes a connection between two devices before data is transferred. This connection ensures that data is delivered without errors, duplication, or loss.

(b) An IP address is a unique numerical identifier assigned to a network device, whereas a port number is a unique numerical identifier assigned to a process running on a network device.

The role of IP addresses and port numbers in selecting the final destination of data is as follows:

An IP address determines the destination network and device to which the data is to be sent. The network address part of an IP address identifies the destination network, whereas the host address part identifies the specific device. This helps the network layer to forward the data to the correct network and device.

A port number determines the specific process or service running on the destination device that is responsible for handling the incoming data. Port numbers range from 0 to 65,535, with certain numbers reserved for specific applications. By identifying the specific process or service on the destination device, the port number enables the Transport layer to deliver the incoming data to the correct process or service.

char * p = str ;
Whom does p point to?
A Point to 'a'
B Point to ^ prime b'
C Point to ^ prime e'
D Point to ^ prime backslash 0'

Answers

The answer is B: p points to 'b'. After the operation p++, the pointer p, which was initially pointing to the start of the string (i.e., 'a'), is incremented to point to the next character in the string, which is 'b'.

In the C programming language, a pointer is a variable that stores the memory address of another variable. In your provided code, `char * p = str;` defines p as a pointer to a character, and assigns it the memory address of the variable `str`. As `str` is an array, this means p initially points to the start of the string "abcde", i.e., the character 'a'. However, the operation `p++` increments the pointer, causing it to point to the next character in the memory sequence, which is the 'b' character. Therefore, after the increment operation, p points to 'b'.

Answers

A parameter is a variable in a function's definition, while an argument is the actual value passed to the function when it is called.

When defining a function, parameters serve as placeholders for the values that will be supplied later. They help specify the function's structure and allow for flexibility in accepting different values. On the other hand, arguments are the concrete values that are passed to the function when it is invoked. These arguments can be literals, variables, or even the result of other expressions.

By providing input parameters, programmers can influence a function's output. The values passed as arguments can affect the behavior and outcome of the function, as the function can perform calculations, operations, or manipulations based on the provided input. The function's implementation can make use of the arguments to generate a result that may vary depending on the values received.

In summary, the parameters act as placeholders in the function's definition, while the arguments are the actual values that are passed to the function when it is called. By manipulating the arguments, programmers can influence the output of the function and customize its behavior according to their specific needs.

VMs running on a hypervisor consume which of the following resources? (Choose three.)
Virtual RAM, Virtual CPUs, Memory Pools

Answers

VMs running on a hypervisor consume the following resources: Virtual RAM, Virtual CPUs, Memory Pools.

When virtual machines (VMs) run on a hypervisor, they rely on various resources to function properly. The first resource is Virtual RAM, also known as memory. Each VM is allocated a portion of the host system's physical RAM, which is presented to the VM as virtual RAM. This virtual memory is used by the VM to store its running processes and data.

The second resource is Virtual CPUs. The hypervisor assigns a specific number of virtual CPUs to each VM. These virtual CPUs represent the processing power that the VM can utilize. The hypervisor manages the allocation of physical CPU cycles to the virtual CPUs of the VMs, allowing them to run their applications and perform computing tasks.

Lastly, VMs consume resources from Memory Pools. Memory pools are a feature provided by some hypervisors to manage the distribution and allocation of memory resources among VMs. Memory pools allow administrators to define limits and shares for different VMs, ensuring fair distribution of memory resources based on priority and resource requirements.

By managing these resources, the hypervisor enables multiple VMs to coexist on a single physical host, sharing the underlying hardware resources effectively. It provides isolation and resource allocation mechanisms to ensure optimal performance and resource utilization.

Joe Heffernan decided to start a snow removal business in his neighbourhood, which he called Snow Care. He invested his used truck into the business on November 1, 2020. Joe had purchased the truck on November 1, 2017, for $14,500. He looked up the fair market value of his truck on a popular web site and arrived at a value for his truck of $6,690 as of November 1,2020 . At that time, he used $2,500 from his savings account to pay for the overhaul needed in order to prepare the truck for pushing a heavy plow. Then, after investing additional cash into the business, Snow Care was able to purchase, on November 5 , a brand new snow plow to be attached to the truck, at a cost of $4,550. The apparatus to attach and operate the plow cost $500. In order to operate the truck on the streets, Joe was required to upgrade his driver's licence at a cost of $420 per year (\$35 per month), add commercial use to his truck insurance at $100 per month, and purchase a $280 business licence that was valid for one year. Based on its seasonal operations, Joe determined that his business should depreciate the truck and plow using the units-of-production method. When making this decision, Joe also considered the estimate of the residual values of these two assets. He believes that the truck will last another four years and be driven a total of 65,000 kilometres, at which time it could be sold for $740. In the case of the plow, estimated units of production will also be 65,000 kilometres and the residual value is expected to be $500, after four year use.

Domestic and external consumer demand faces headwinds, even as supplychains within China are challenged by wide-ranging restrictions on movement designed to counter the spread of Covid-19 cases.As of mid-April, pandemic-related public health restrictions affected all but 13 of the top 100 cities by GDP, according to research firm Gavekal, with a number of large regions such as Shanghai and Jilin facing full lockdowns for parts of March and April. These measures have added further challenges to policymakers efforts to stabilise economic momentum, after the emergence of housing-sector strains from mid-2021 that led some developers into distress.Dented consumer confidence was evident in a quarterly survey released at end-1Q22 by the Peoples Bank of China. This showed urban residents intended to reduce spending and investment, despite improved perceptions about household income and employment. It indicated that households intend to cut discretionary spending, focusing instead on essential items, education and healthcare. Retail sales also fell yoy in March.Fitch expects Chinas retail sales growth to decelerate to mid-single digits in 2022 from 12.5% in 2021, given weaker consumer sentiment, the impact of lockdowns and the high base effect for 1H22. Sectors that benefit from discretionary spending, including tourism, entertainment and luxury goods, are likely to underperform essentials. This could put pressure on the ratings of more vulnerable firms in these discretionary sectors.Demand pressures for Chinese corporates will be aggravated by softer consumer demand in developed markets. This reflects, in part, high levels of inflation and the tightening of monetary policy - in contrast to trends in China, where consumer price inflation remains low - as well as a normalisation of demand patterns after the surge in goods purchases during the pandemic. Chinas goods export growth slowed to 15.8% yoy in 1Q22, from 29.9% in full-year 2021.Demand pressures have been accompanied in recent weeks by an increase in supply chain problems associated with movement restrictions. Several companies have reportedly halted production owing to difficulties in transporting inputs and finished products. We expect manufacturers with long supply chains - such as automotive, aerospace and consumer technology firms - to be more exposed to this issue. Effects on output may prove temporary (and recoverable) if the authorities succeed in containing Covid-19 cases, but we believe there is a risk disruption could continue for months as new outbreaks emerge and are suppressed.Subdued consumer sentiment has impeded companies ability to pass on higher input costs. Consumer price inflation has been below producer price inflation, in yoy terms, since January 2021, suggesting that downstream corporates are absorbing higher upstream costs. This may have adverse effects on their profitability, and in turn on their standalone creditworthiness. However, this impact could be offset by other factors, such as reducing capex due to the weaker demand outlook. Moreover, exporters have been better able to raise prices, passing on higher costs to overseas customers.Higher commodity prices should be broadly credit positive for upstream industrial corporates. In 2M22 profits among large mining and quarrying firms rose by 132% yoy while those of manufacturers dropped by 4.2%.Weak consumer sentiment may prompt the government to accelerate counter-cyclical policy support, notably in infrastructure investment. This would likely skew activity further towards heavy industry and upstream industrial corporates, at least in the near term.https://www.fitchratings.com/research/corporate-finance/china-corporates-face-mounting-demand-supply-challenges-19-04-20222.2 Critically evaluate GDP as a measure of economic growth. Cyclone Industrial Corp. is evaluating the launch of a new tractor. - The manufacturing machine needed for the production has an initial cost of $450,000, which will be depreciated straightline to a book value of $50.000 over its five-year life. - The new tractor is expected to generate $650,000 in annual sales, with annual production costs of $250,000. These sales and costs are before-tax figures. - The marginal tax rate is 35 percent. What are the operating cash flows (OCF) over the lifetime of the new tractor? $208,000 per year from vear 1 to year 5 $291,500 per vear from year 1 to year 5 $236,000 per year from year 1 to year 5 $288,000 per year from year 1 to year 5 Question 13 of 15 < > 0.59 / 1 : View Policies Show Attempt History Current Attempt in Progress Your answer is partially correct.
