a and b are positive integers and a−b=2. Evaluate the following: 4^0.5a/ 2^b

Answers

Answer 1

Answer: [tex]\frac{4^{0.5 a}}{2^{b}}=4[/tex]

Step-by-step explanation:

We are told [tex]a-b=2[/tex] being [tex]a[/tex] and [tex]b[/tex] positive integers, hence:

[tex]a=2+b[/tex] (1)

Now we have the following expression:

[tex]\frac{4^{0.5 a}}{2^{b}}[/tex] (2)

Which can be also written as:

[tex]\frac{2^{2(0.5 a)}}{2^{b}}[/tex] (3)

Since [tex]4=2^{2}[/tex]

Then, substituting (1) in (3):

[tex]\frac{2^{2(0.5(2+b))}}{2^{b}}[/tex] (4)

Since we have exponents with the same base, we can do the following:

[tex]\frac{2^{2+b}}{2^{b}}=2^{2+b} 2^{-b}[/tex] (5)

Finally:

[tex]2^{2+b} 2^{-b}=2^{2+b-b}=2^{2}=4[/tex] (6)

Hence:

[tex]\frac{4^{0.5 a}}{2^{b}}=4[/tex]

Find P (Sheep | Male)

Answers

Answer: I got 2/7

Step-by-step explanation:

The required probability of the sheep being male is 2/7 or 0.286 or 28%.

Given that,
Tabulated data has been given in the image for cow, sheep, horse chicken, and pigs for their male and female frequencies.
Probability for sheep in males to be determined.

What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events. Probability = Favorable Events / Total outcomes

Total number of male S(n) = 14
Number of male sheep E(n) = 4
Probability for sheep in males = E(n) / S(n)
                                                  = 4 /14
                                                  = 2 / 7

As part of a competition Diego must spin around in a circle six times and then run to a tree. The time he spends on each spin is represented by s and the time he spends running is r. He gets to the tree 21 seconds after he starts spinning. Write an equation showing the relationship between s and r.

Answers

Answer:

6s + 2r = 21

Step-by-step explanation:

Please kindly see the attached file for explanaion

The correct equation showing the relationship between s and r is 6s + r = 21

To derive this equation, we consider the total time Diego spends on the competition, which is the sum of the time he spends spinning and the time he spends running.

Since Diego spins around in a circle six times and each spin takes time s, the total time spent spinning is 6s

After spinning, he runs to the tree, which takes time r.

Therefore, the total time from the start of the spinning until Diego reaches the tree is the sum of the time spent spinning and running.

 Given that Diego reaches the tree 21 seconds after he starts spinning, we can set up the following equation to represent this relationship:

6s + r = 21

 This equation states that six times the time spent on each spin plus the time spent running equals 21 seconds.

Solving this equation for either s or r would give us the time spent on each activity, provided we know the total time of 21 seconds.

Final answer:

The equation that best describes the relationship between the number of students and the number of tables is N = 40t. This equation can be obtained by observing the given data points and identifying the pattern. It can be verified by substituting the values of the number of students and tables.

Explanation:

The equation that best describes the relationship between the number of students and the number of tables is N = 40t, where 'N' represents the number of students and 't' represents the number of tables. This equation is obtained by observing the given data points and identifying the pattern. For example, when the number of tables is 18, the number of students is 720, which can be represented as 720 = 40 * 18.

To verify this equation, let's check the other given data points. When the number of tables is 15, the number of students is 600, which can be represented as 600 = 40 * 15. Similarly, when the number of tables is 24, the number of students is 960, which can be represented as 960 = 40 * 24. Therefore, the equation N = 40t best represents the relationship between the number of students and the number of tables.

Factor the following polynomial:
5x(a-b)-2y(a-b)

Answers

Answer:

(a - b)(5x - 2y)

Step-by-step explanation:

Given

5x(a - b) - 2y(a - b) ← factor out (a - b) from each term

= (a - b)(5x - 2y) ← in factored form

Final answer:

The polynomial 5x(a-b)-2y(a-b) can be factored into (a-b)(5x-2y). This is achieved by taking out the common factor of (a-b) from both terms.

Explanation:

To factor the polynomial

5x(a-b)-2y(a-b)

, you first notice that the terms have a common factor, (a-b). Factoring is a process where you write the expression as a product of its factors. In this case, you can pull out the common factor from both terms. This leaves you with

(a-b)(5x-2y)

. So, the factored form of the given polynomial is (a-b)(5x-2y). By applying the distributive property, you can check your work: (a-b)*5x gives the first term and (a-b)*(-2y) gives the second term, confirming the factored form is correct.

Timothy’s mom bought 7/8 of a pound of grapes. She wants to split it between 8 kids. What fraction of the grapes will each kid get?

A. 1/8

B. 7/64

C. 9/64

Answers

Answer:

Option B

7/64

Step-by-step explanation:

Since the she bought 7/8 of a pound of grapes, the amount of grapes that Timothy's mum will be sharing is only 7/8 of a pound

Total number of kids = 6

To get the amount that each kid will get, we will have to divide 7/8 by 6

Hence we have

[tex]\frac{7}{8} \times \frac{1}{6}= \frac{7}{64}[/tex]

Hence, each child will get 7/64 of a pound of grapes, if the grapes are shared equally.

Answer:

B. 7/64

Step-by-step explanation:

Since Timothy's mom bought 7/8 of a pound of grapes, the amount of grapes that she will split between 8 kids will be:

7/8 ÷ 1/8 = 7/64

Therefore, each kid will get 7/64 of a pound of grapes, if the grapes are splitted equally.

Find length of PR. TR=x+11

Answers

Step-by-step explanation:

In a square,

we know that when diagonals bisect each other it is divided into two equal parts

so

TR = TP

So

PR = x +11 + x + 11

= 2x + 22

And

Both diagonals are equal so

QS = PR

7x - 3 = 2x + 22

7x - 2x = 22 + 3

5x = 25

x= 25 /5

x = 5

Now

PR = 2 * 5 +22= 10 +22 = 32

Answer:

PR = 34

Step-by-step explanation:

The diagonals of a square bisect each other, and are congruent, thus

QS = PR, that is

7x - 8 = x + 11 + x + 11 = 2x + 22 ( subtract 2x from both sides )

5x - 8 = 22 ( add 8 to both sides )

5x = 30 ( divide both sides by 5 )

x = 6

Thus

PR = 2x + 22 = 2(6) + 22 = 12 + 22 = 34

y=4x

Step-by-step explanation:

First, find the slope

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

We know 2 points, (2,8) and (12,48).

(2,8) can be (x1, y1)

(12,48) can be (x2, y2)

We can say that y2 is 48, y1 is 8, x2 is 12, and x1 is 2. Substitute them in

[tex]m=\frac{48-8}{12-2}[/tex]

[tex]m=\frac{40}{10}[/tex]

m=4

Now, we can use the point slope formula, since we have a point and the slope

[tex]y-y_{1} =m(x-x_{1})[/tex]

We know m, the slope is 4. We also know a point (2,8), which is (x1, y1). Substitute them in

y-8=4(x-2)

Distribute the 4

y-8=4*x-2*4

y-8=4x-8

Add 8 to both sides

y=4x

Answer:

y=4x

Step-by-step explanation:

You are given 3 points that are on this line. (0,0) which is the origin, (2,8) and (12,48)

Find the slope with (2,8) and (12,48)

Remember the slope formula:

(y2-y1) / (x2 - x1)

So:

(48 - 8) / (12 - 2)

40/10 = 4

And the y- intercept is 0 because the line goes through the origin.

So the equation is:

y=4x

To go to a movie, a family with 2 adults and 4 children spends $64. A family containing 1 adult and 3 children spends $42. Find the cost of an adult movie ticket and the cost of a child movie ticket.

Answers

Answer:

all work is pictured and shown

The cost of a ticket for an adult is $12 while for children it is $10.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

Let's assume that cost for adults is A while for children it is C

Now,

2 adults and 4 children spend $64.

2A + 4C = 64

1 adult and 3 children spend $42.

A + 3C = 42

Multiply by 2

2A + 6C = 84

By subtracting equations

6C - 4C = 84 - 64

2C = 20

C = 10

A = 42 - 3(10)

A = 12

Hence "The cost of a ticket for an adult is $12 while for children it is $10".

If a central angle measures 87°, then its arc will measure
half as much
twice as much
the same

Answers

Answer:

Half 43.5

The same 87

Twice as much 174

Step-by-step explanation:

The arc measure is approximately [tex]\(1.518 \pi\)[/tex] times the central angle. So, it's larger. The answer is B.

To find the measure of the arc corresponding to a central angle, you can use the formula:

[tex]\[ \text{Arc measure} = \frac{\text{Central angle}}{360^\circ} \times \text{circumference of the circle} \][/tex]

Since a full circle has a circumference of [tex]\( 2\pi \)[/tex] units, and the central angle is 87 degrees, you can substitute these values into the formula:

[tex]\[ \text{Arc measure} = \frac{87^\circ}{360^\circ} \times 2\pi \][/tex]

[tex]\[ \text{Arc measure} = \frac{87}{360} \times 2\pi \][/tex]

[tex]\[ \text{Arc measure} \approx 0.2417 \times 2\pi \][/tex]

[tex]\[ \text{Arc measure} \approx 1.518 \pi \][/tex]

Now, compare the result to the central angle. Since the arc measure is approximately [tex]\(1.518 \pi\)[/tex], and the central angle is 87 degrees, it's clear that the arc is larger than the central angle. So the correct answer is:

B. Twice as much

If the risk-free rate is 8 percent and the market risk premium is 2 percent, what is the required return for the market?

Answers

Final answer:

The required return for the market can be calculated using the Capital Asset Pricing Model (CAPM), which takes into account the risk-free rate, beta value, and market risk premium.

Explanation:

The required return for the market can be calculated using the Capital Asset Pricing Model (CAPM). The CAPM formula is:

Required Return = Risk-Free Rate + Beta * Market Risk Premium

In this case, the risk-free rate is given as 8%, and the market risk premium is given as 2%. To calculate the required return for the market, we need to know the beta value, which represents the stock's sensitivity to market movements.

Once we have the beta value, we can substitute it into the formula to find the required return for the market.

Final answer:

The required return for the market, when the risk-free rate is 8 percent and the market risk premium is 2 percent, is 10 percent according to the Capital Asset Pricing Model.

Explanation:

The student is inquiring about the concept of the required return of the market, which is a fundamental concept in finance related to the Capital Asset Pricing Model (CAPM). According to CAPM, the required return on a market portfolio (the market) is the sum of the risk-free rate and the market risk premium. In this case, with an 8 percent risk-free rate and a 2 percent market risk premium, the required return for the market would be the sum of these two figures, which equals 10 percent.
