An amount of money P is invested in an account where interest is compounded at the end of the period. The future worth F yielded at an interest rate i after n periods may be determined from the following formula: 

F=P(1+i)n.F=P(1+i)n.
Write a program that will calculate the future worth of an investment for each year from 1 through n. The input to the function should include the initial investment P, the interest rate i (as a decimal), and the number of years n for which the future worth is to be calculated. The output should consist of a table with headings and columns for n and F. Run the program for P = $100,000, i=.05, n=10 years F=P(1+i)nF=P(1+i)n

Modify the problem by using the following general formula for compounding interests: F=P(1+i/m)^mn where, m is the number of interest payments per year. Solve the problem for m=1 (annual) and m=12 (monthly).

Answers

Answer 1

Answer:

def future_worth(p,i,n):

   print("n \t F")

   for num in range(1, n+1):

       F = round(p * ((1 + i)** num), 2)

       print(f"{num}\t{F}")

future_worth(100000, .05, 10)

Explanation:

The "future_worth" function of the python program accepts three arguments namely the P (amount invested), i (the interest rate), and n (the number of years). The program runs a loop to print the rate of increase of the amount invested in n number of years.

How we ingest streaming data into Hadoop Cluster?

Answers

Hadoop could be described as an open source program to handle big data. By utilizing the MapReduce model, Hadoop distributes data across it's nodes which are a network of connected computers. This data is shared across the systems and thus enables it to handle and process a very large amount dataset at the same time. These collection of networked nodes is called the HADOOP CLUSTER.

Hadoop leverages the power and capabilities of it's distributed file system (HDFS) which can handle the reading and writing of large files from log files, databases, raw files and other forms of streaming data for processing using ingestion tools such as the apache Flume, striim and so on. The HDFS ensures the ingested data are divided into smaller subunits and distributed across systems in the cluster.

Write a function in Java called factorial() that will take a positive integer as input and returns its factorial as output.

Answers

Answer:

The function is as follows:

public static int factorial(int n){

       int fact = 1;

       for(int i=2;i<=n;i++){

           fact*=i;

       }

       return fact;

   }

Explanation:

This line defines the function

public static int factorial(int n){

This declares and initializes variable fact to 1    

  int fact = 1;

This iterates from 2 to n

       for(int i=2;i<=n;i++){

This line multiplies all integers from 1 to n

           fact*=i;

       }

This returns the factorial

       return fact;

With what speed will a clock have to be moving in order to run at a rate that is one-half the rate of a clock at rest

Answers

Answer:

Speed = 0.866c

Where c is speed of light

Explanation:

We want to find the speed at which it run at a rate that is one-half the rate of a clock at rest.

Thus, we will use time dilation equation to solve it.

Thus;

t_o/√[1 - (v²/c²)] = 2t_o

Where:

t_o is time at rest

v is the speed at which it runs

c is the speed of light.

t_o will cancel out to give;

1/√[1 - (v²/c²)] = 2

Rearranging, we have;

√[1 - (v²/c²)] = ½

Let's make v the subject of the formula;

Let's square both sides to get;

1 - (v²/c²) = ½²

1 - (v²/c²) = ¼

Rearrange to get;

1 - ¼ = v²/c²

¾ = v²/c²

Take square root of both sides to get;

v/c = √¾

v = c × 0.866

v = 0.866c

Answers

Answer:

The function in Java is as follows:

public static void printMessage(String lineOne, String lineTwo, int lines){

       for(int i = 1;i<=lines;i++){

           if(i%2 == 1){

               System.out.println(lineOne);

           }

           else{

               System.out.println(lineTwo);

           }

       }

   }

Explanation:

This defines the function

public static void printMessage(String lineOne, String lineTwo, int lines){

This iterates through the number of lines

       for(int i = 1;i<=lines;i++){

String lineOne is printed on odd lines i.e. 1,3,5....

      if(i%2 == 1){

               System.out.println(lineOne);

           }

String lineTwo is printed on even lines i.e. 2,4,6....

           else{

               System.out.println(lineTwo);

           }

       }

   }

To call the function from main, use:

printMessage("Hi", "Karel", 5);

Answers

Correct question:

What is the missing line?

>>> myDeque = deque('math')

>>> myDeque

deque(['m', 'a', 't'])

Answer:

myDeque.pop()

Explanation:

The double ended queue, deque found in the python collection module is very similar to a python list and can perform operations such as delete items, append and so on.

In the program written above, the missing line is the myDeque.pop() as the pop() method is used to delete items in the created list from the right end of the list. Hence, the 'h' at the right end is deleted and we have the output deque(['m', 'a', 't'])

myDeque.popleft () deletes items from the right.

Write a program that accomplishes the following objectives:
1. reads in the number of rows, then the number of columns,
2. using nested FOR loops, reads in the column data for each row,
3. adds up the data for each row and derives an average for each row,
4 also adds up all the data in the table and derives an overall average.
Hints
1. Look at slides 3 and 4 of CS1336_Lect5e_nested_loops.pptx and Pr5-14.cpp for samples of nested FOR loops, especially line 38 in slide 4 for a calculation of average per student. That is very much like a row average.
2 Have two running total variables, for example rowsum and totalsum. Initialize totalsum to 0 in the beginning of the program Initialize rowsum to 0 before the inner loop (see line 29 in slide 4). Keep running totals for both of these inside the inner loop (see line 36 in slide 4). Average the rowSum after each iteration of the inner loop (see line 38 in slide 4). Average the totalsum after the outside loop ends
When the input is as shown in Figure 1. your program should produce the output as shown in Figure 2.
Figure 1: (sample input) 23 23.1 13.58 14 56.783 46.29 45.71

float nums[rows][cols];

for(int i = 0;i<rows;i++){

for(int j = 0;j<cols;j++){

cout<<"Row "<<i+1<<", Column "<<j+1<<": ";

cin>>nums[i][j];

rowsum+=nums[i][j];  totalsum+=nums[i][j];

}

cout<<"Average of row "<<i+1<<": "<<(rowsum*1.0/cols*1.0)<<endl;

rowsum = 0;

}

cout<<"Overall Average: "<<(totalsum*1.0)/(rows*cols*1.0);

return 0;

}

Explanation:

This line declares number of rows and number of columns as integer

int rows, cols;

This line prompts user for number of rows

cout<<"Rows: "; cin>>rows;

This line prompts user for number of columns

cout<<"Columns: "; cin>>cols;

This line initializes rowsum and totalsum to 0, respectively

int rowsum = 0; int totalsum = 0;

This line declares a 2d array

float nums[rows][cols];

The following iteration gets user input into the array

for(int i = 0;i<rows;i++){

for(int j = 0;j<cols;j++){

cout<<"Row "<<i+1<<", Column "<<j+1<<": ";

cin>>nums[i][j];

This line sum up the rows

rowsum+=nums[i][j];  

This line sum up each entry

totalsum+=nums[i][j];

}

This line calculates and prints the average of each row

cout<<"Average of row "<<i+1<<": "<<(rowsum*1.0/cols*1.0)<<endl;

rowsum = 0;

}

This line calculates and prints the overall average

cout<<"Overall Average: "<<(totalsum*1.0)/(rows*cols*1.0);

Which daemon manages the physical memory by moving process from physical memory to swap space when more physical memory is needed

Answers

Answer:

Swap daemon

Explanation:

Swap daemon manages the physical memory by moving process from physical memory to swap space when more physical memory is needed. The main function of the swap daemon is to monitor processes running on a computer to determine whether or not it requires to be swapped.

The physical memory of a computer system is known as random access memory (RAM).

A random access memory (RAM) can be defined as the internal hardware memory which allows data to be read and written (changed) in a computer.Basically, a random access memory (RAM) is used for temporarily storing data such as software programs, operating system (OS),machine code and working data (data in current use) so that they are easily and rapidly accessible to the central processing unit (CPU).

Additionally, RAM is a volatile memory because any data stored in it would be lost or erased once the computer is turned off. Thus, it can only retain data while the computer is turned on and as such is considered to be a short-term memory.

There are two (2) main types of random access memory (RAM) and these are;

1. Static Random Access Memory (SRAM).

2. Dynamic Random Access Memory (DRAM).

Write a Java program that asks the user to enter an array of integers in the main method. The program will ask the user for the number of integer elements to be put in the array, and then ask the user for each element of the array. The program then calls a method named isSorted() that accepts an array of integers and returns true if the list is in sorted (increasing) order and false otherwise. For example, if arrays named arr1 and arr2 store [10, 20, 30, 41, 56] and [2, 5, 3, 12, 10] respectively, the calls isSorted(arr1) and isSorted(arr2) should return true and false respectively. Assume the array has at least one integer element. A one-element array is considered to be sorted.

Answers

Answer:

The program is as follows:

import java.util.Scanner;

public class MyClass {

   public static Boolean isSorted(int [] arr){

       Boolean sorted = true;

       for(int i = 0;i<arr.length;i++){

       for(int j = i;j<arr.length;j++){

           if(arr[i]>arr[j]){

               sorted = false;

               break;

           }

       }    

       }

       return sorted;

   }

   public static void main(String args[]) {

       Scanner input = new Scanner(System.in);

       int n;

       System.out.print("Length of array: ");

       n = input.nextInt();

       int[] arr = new int[n];

       System.out.println("Enter array elements:");

       for(int i = 0; i<n;i++){

           arr[i] = input.nextInt();

       }

      Boolean chk = isSorted(arr);

     System.out.print(chk);

   }

}

Explanation:

The method begins here

This line defines a method named isSorted

   public static Boolean isSorted(int [] arr){

This line declares a boolean variable and initializes it to true

       Boolean sorted = true;

The next two iterations iterate through elements of the array

       for(int i = 0;i<arr.length;i++){

       for(int j = i;j<arr.length;j++){

This compares an array element with next elements (to the right)

           if(arr[i]>arr[j]){

If the next element is smaller than the previous array element, then the array is not sorted

               sorted = false; The boolean variable is updated to false

               break; This breaks the loop

           }

       }    

       }

This returns true or false, depending on the order of the array

       return sorted;

   }

The main method begins here

public static void main(String args[]) {

       Scanner input = new Scanner(System.in);

       int n;

This prompts user for length of array

       System.out.print("Length of array: ");

This gets length of array from user

       n = input.nextInt();

This declares an array

       int[] arr = new int[n];

This prompts user for array elements

       System.out.println("Enter array elements:");

The following iteration gets the array elements

       for(int i = 0; i<n;i++){

           arr[i] = input.nextInt();

       }

This calls the isSorted array      

     Boolean chk = isSorted(arr);

This prints true or false, depending if the array is sorted or not

     System.out.print(chk);      

   }

The mowers work when the user plugs an extension cord into the outlet and into the machine. In order to start the machine, the user must pull a lever and hold it while pushing a button. You believe that your mower is extremely safe. It contains several warnings about using it only on grass, that it is not to be used to shred tree branches or other wood products, and that it is not to be used without the bag attachment for catching the grass that is thrown out the back. A customer sues your company after being hurt when he used the electric lawn mower during a rainstorm. Discuss whether or not your company should have included a warning label to address use of the electric lawn mower in the rain.
