what performs all arithmetic operations (for example, addition and subtraction) and all logic operations?

Answers

An arithmetic logic unit (ALU) performs all arithmetic operations (for example, addition and subtraction) and all logic operations.

An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU).

Basic arithmetic and logical operations are carried out using an ALU. Addition, subtraction, multiplication, and division are a few examples of arithmetic operations.

Binary numbers, or 0 and 1, are used to store and modify every piece of data in computers. Since a switch has just two possible states—open or closed—transistor switches are used to alter binary numbers. An open transistor, through which no current flows, is equivalent to a 0. A closed transistor with a current flowing through it symbolizes a 1.

At the end of six years, the balance in Merle's account is (use the tables in the handbook):

A.

$73,604.00

B.

$53,604.00

C.

$80,406.00

D.

$98,636.72

E.

None of these

Answers

The correct option D. $98,636.72; is the amount in Merle's account after six years.

Explain the term compounded semiannually?Interest compounded semiannually indicates that its compound interest rate is determined on the bases of the principal combined with the outcomes of the compound interest rate as from previous term's computation, and this will occur twice a year.

The formula for the compound interest is-

A = P * (1 + r/nt)^nt

In which,

A = amount after compounding.P = principal amountr = rate of interestt = total time in yearsn = number of time amount compounded

From the beginning to end of the third year:

A = P(1 + 0.05 )^6

A = 40,000 × 1.05^6

A = $53,603.83

Now, add $20,000 to the amount obtained.

A = $53,603.83 + $20,000

A = $73,603.83

Thus, at the end of sixth year:

A = 73,603.83 x 1.05^6

A = $98,636.16

Therefore, the balance in Merle's account after six years is  $98,636.16.

1. find the formula for an exponential function that passes through the points (-1, 3/2) and (3, 24).

Answers

The formula for an exponential function is y = 45/8x + 57/8.

Here we have to find the formula for an exponential function that passes through the points.

Given data:

The two points are (-1, 3/2) and (3, 24).

We need to find the slope of the line. So,

Slope(m) = (y2 - y1) / (x2 - x1)

m = (24 - 3/2) / ( 3+ 1)

   = 45/ 8

The general equation of a line:

y = mx + c

Now putting the value of x and y as -1 and 3/2 and m = 45/8.

3/2 = -1 × 45/8 + c

c = 57/8

Now we get the equation:

y = 45/8x + 57/8

Therefore the equation is y = 45/8x + 57/8.

what is the potential difference between the center of the sphere and the surface of the sphere?

Answers

Possible distinction between  the center of the sphere and  surface of the sphere is

A notable distinction is made by the fact that the surface is three-dimensional, while the sphere's centre is a (non-dimensional) point, and that their values are independent of one another.If the sphere is a conducting hollow sphere, its centre and surface have the same potential. A perfect conductor has no electric field at all.A dielectric sphere's core has zero potential, while the surface has a potential of KQ/(R).

The sphere is one of the most significant mathematical figures. Spheres and nearly-spherical objects can be seen in both nature and industry.

Soap bubbles and other bubbles have a spherical shape when they are in an equilibrium state. The celestial sphere is a fundamental concept in astronomy, and the Earth is usually represented as spherical in geography.

Step-by-step explanation:

The composition of two functions f and g, denoted g(f(x)), is a new function that is obtained by substituting the function f(x) into the function g(x) in place of x.

In this case, f(x) = x + 1 and g(x) = 2x. Substituting f(x) into g(x) in place of x gives us g(f(x)) = 2(x + 1) = 2x + 2.

Therefore, the final expression for g(f(x)) is 2x + 2. The coefficient of x is 2, and the constant term is 2.

Ans:Rs.42500​

Answers

The amount of commission the agent receives if the bonus amount is Rs. 1,500, is Rs. 24,000.

How the commission is computed:

To find the commission received by the agent, we first determine the excess sales using the bonus rate and bonus amount.

The excess sales are added to Rs. 900,000 to determine the total sales for the year.

The commission rate is applied to the total sales to ascertain the amount of the commission the agent received.

Commission on the total annual sales = 2%

Bonus on the excess of sales over Rs. 900,000 = 0.5%

Bonus amount = Rs. 1,500

Excess sales over Rs. 900,000 = Rs. 300,000 (Rs. 1,500/0.5%)

Total sales = Rs. 1,200,000 (Rs. 900,000 + Rs. 300,000)

Commission amount = Rs. 24,000 (Rs 1,200,000 x 2%)

What is meant by symmetry of data?

A data is symmetric when it has a mirror image on both sides of the mean. For a symmetric data the mean = mode = median.

What is left-skewed data?

If the data is asymmetric, it can either be left-skewed or right-skewed. A left-skewed data has mots of its values greater than the mean. In this case the mean < median < mode. Left-skewed data mostly contains very less amount of values with smaller magnitudes.

Hence, data that are left-skewed would include values that are unusually high.

Answers

The  probability that between 78% and 86% were non-teacher workers from private schools is 0.7689

Eighty-four percent of non-teacher workers were employed in private schools.

p = 0.84

q = 1 - p = 1 - 0.84 = 0.16

if a random sample of 200 non-teacher workers from private schools was selected

We need to find the  probability that between 78% and 86% were non-teacher workers from private schools.

n = 200

μρ = 0.84

αp = √(p(1 - p)/n) = √(0.84(0.16)/200) = 0.026

P(0.78 < P < 0.86) = P((0.78 - 0.84)/0.026 < (p - μp)/σp < (0.86 - 0.84)/0.026)

= P(-2.31 < z < 0.77)

= P(z < 0.77) - P(z < -2.31)

using z table

0.7794 - 0.0103

= 0.7689

Therefore, the  probability that between 78% and 86% were non-teacher workers from private schools is 0.7689.

Answers

Ages (in years) of a sample of retirement home inhabitants is option B. For the lowest wait time, the maximum frequency is anticipated to be right-skewed. A desert cannot have a maximum annual temperature of 60°F, and it is not conceivable to watch 60+ hours of TV in a single day.

Residents of senior living facilities are typically 84 years old. While there are many couples in these communities, the majority of people who live in independent living are women. Some people move in at or near the minimum age (often around 65), but most people do so between the ages of 75 and 84. Residents come from all different backgrounds.

Many people are choosing senior living in a community environment, including teachers, nurses, small business owners, big business CEOs, university professors, housewives, lawyers, engineers, musicians, and more. Current residents will attest that the rich diversity of origins fosters amazing interactions and relationships. And contrary to popular belief, the majority of residents of independent living are quite active.

AplL tions and interpreting them in terms of chemical equations. You will also use a simple classification scheme for grouping chemical reactions by type. Finally, you will practice quantitative lab techniques by trying to recover the copper with minimal loss. AN OVERVIEW OF THE COPPER CYCLE One of the most fascinating aspects of laboratory experiments to new chemistry students is the variety of colors, odors, and textures encountered. The present experiment demonstrates that aspect by a sequence of striking changes in color, appearance, and bulk. By going through this experiment, students will develop laboratory techniques by the challenges of shepherding copper through all chemical changes with minimal loss. A schematic outline of the chemical reactions involved in the experiment is shown in Figure 5-1 HNO Cu(NO)2 Cu (1) NaOH (2) Zn (5) Cu(OH), 9VOA CUSO je() A (heat) 1000 Ht H,SO Cuo Figure 5-1. A schematic outline of the series of chemical reactions in the copper cycle. The overall copper cycle is then given as Cu(NO,)2(aq) Cu(s) Cu(OH)2(s) CuO(s) CUSO,(aq) Cu(s) The balanced equations corresponding to these steps are: Nitric acid is not only a strong acid but also a strong oxidizing agent, making it a very effective solvent for most metals. 1. (1) 4HNO,(aq)+ Cu(s) Cu(NOs)2(aq) + 2H20(l) + 2NO2(g) Many heavy metals form insoluble hydroxides which can be precipitated from solutions by sol- uble hydroxides such as NaOH. 2. (2) Cu(OH)2(s) + 2NANO,(aq) Cu(NO,)2laq) + 2NaOH(aq) Many transition metal hydroxides lose water upon heating, thus changing to oxides. For copper, this reaction happens at a relatively lower temperature and is accompanied by a striking color change, from blue to black. 3. (3) Cu(OH)2(s)Cu0(s) + H20(e) 4. Metal oxides, being base an hydrides, form salts with acids just as readily as do the bases themselves. CuO(s) + H,SO(aq) CuSO(aq) + H20(e) (4) 5. Chemically active metals, such as zinc, readily displace less active metals from their salts. CuSO&(aq) + Zn(s) Cu(s) + ZnSO(aq) (5) 6. The reaction used to remove excess Zn(s) left over from eq(5): Zn(s) +2H*(aq) Zn2t(aq) + H(g) (6) The last reaction is not explicitly shown in the cycle, but actually occurs twice. The first reaction is with H from excess HSO, as a side reaction during the reduction of CuSO and the second one is with HCL, as an intentional step for the removal of excess Zn remaining in solution after reduction of Cu2+ to Cu. Each equation, as given above, describes one of the colorful transformations, but it is easy to lose sight of their physical meaning if you merely look upon them as a bunch of symbols written on paper. To become more familiar with the chemical equations it is essential to try the following: Find out what the compounds, represented by the formulas, actually look like and what their chemical properties are. a. What class of compounds they belong to, e.g. acid, salt, etc., and what the generic properties of this class are, ie. what types of reactions they undergo. b. Similarly, try to categorize the equations (actually, the reactions they represent): oxidation- reduction (redox) reaction, acid-base reaction, precipitation reaction, replacement reaction, C. etc CLASSIFICATION OF CHEMICAL REACTIONS Precipitation In a precipitation reaction, two soluble substances react to form an insoluble compound, e.g. (7) CaCl2+ Na COs CaCO,(s) + 2NaCl CACO3 is insoluble in water so this salt will form a precipitate and fall out of the solution. 45 LAB 5: A CYCLE OF CHEMICAL REACTIONS OF COPPER soil is a reservoir for the pathogen for all of the following diseases except group of answer choices histoplasmosis. melioidosis. q fever. blastomycosis. coccidioidomycosis. if the reaction begins with 95.00 grams of cr2o3 and 183.0 grams of silicon, how many grams of the excess reactant will be used?
