Given the functions:

f(x)=1/4x+5

g(x)=4x-20​

The functions g and f are said to commute with each other if g ∘ f = f ∘ g.

Let's check the functions if they are commutative.

a.) f ∘ g = f(g(x))

b.) g ∘ f = g(f(x))

Conclusion:

g ∘ f = f ∘ g

Therefore, the functions are commutative.

Among the given options, no one is an equivalent expression.

What is an equivalent expression?

Vertical asymptotes are when the denominator is 0 but the numerator isn't 0.

[tex]x-36=0 \implies x=36[/tex]

Since this value of x does not make the numerator equal to 0, the vertical asymptote is [tex]x=36[/tex].

Horizontal asymptotes are the limits as [tex]x \to \pm \infty[/tex].

[tex]\lim_{x \to \infty} \frac{6x}{x-36}=\lim_{x \to \infty}=\frac{6}{1-\frac{36}{x}}=6\\\\\lim_{x \to -\infty} \frac{6x}{x-36}=\lim_{x \to -\infty}=\frac{6}{1-\frac{36}{x}}=6\\\\[/tex]

So, the horizontal asymptote is [tex]y=6[/tex].

For this question, we use the following formula for compounded interest:

Solving for a we get:

[tex]k=4[/tex].

[tex]20 +7k = 8(k + 2)[/tex]

[tex]20 +7k = 8k+16[/tex]

[tex]-20+20 +7k = 8k+16-20\\ \\7k = 8k-4[/tex]

[tex]7k-8k = 8k-4-8k\\ \\-k = -4[/tex]

[tex](-1)-k = -4(-1)\\ \\k=4[/tex]

[tex]20 +7(4) = 8((4) + 2)\\ \\20 +28 = 8(6)\\ \\48=48[/tex]

[tex]k=4[/tex].

Answer:

k = 4

Step-by-step explanation:

a) Simplify both sides of the equation.

20 + 7k = 8(k + 2)

20 + 7k = (8)(k) + (8)(2)

20 + 7k = 8k + 16

7k + 20 = 8k + 16

b) Subtract 8k from both sides.

7k + 20 − 8k = 8k + 16 − 8k

−k + 20 = 16

c) Subtract 20 from both sides.

−k + 20 − 20 = 16 − 20

−k = −4

Divide both sides by -1.

-k/-1 = -4/-1

k = 4

Answer: f(h) = (2 pi (5x + 2)^2)

Step-by-step explanation:

1) Set the area of the circle in an equation

f(h) = pi r ^2

2) Set r to the rate that the circle is growing

The rate is 5x +2 because its starting value is two, and the 5x because it is growing 5 inches per hour.

f(h) = (2 pi (5x + 2)^2)

To find: After how many months of saving do Sam and Frank have the same amount in their accounts and how much do they have in their accounts at this time

From the graph,

x axis represents number of months,

axis represents Amount saved.

The red graph represents the amount saved by Sam over the number of months

The blue graph represents the amount saved by Frank over the number of months

To find the intersection point of the two graphs.

The intersection point is (4,80)

After 4 months Sam and Frank saved $80.

Hence we get that,

After 4 months, Sam and Frank have the same amount in their accounts. They have $80 in their accounts.

Answer is: After 4 months, Sam and Frank have the same amount in their accounts. They have $80 in their accounts.

The rate of change is 65 miles per hour

Given the ordered pairs (1, 65) and (2, 130)

The rate of change is given as:

The rate of change is 65 miles per hour

Using the average rate of change, it is found that:

A. The average population decline between 1984 and 2018 was of 2.25 thousand deer a year.

B. The population would have reached 225 thousand deer between 2017 and 2018.

C.

The rates are as follows:

Meaning that between 1994 and 2004 there was a increase in the population of deer, and from 2004 to 2014 there was a decrease.

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

For 1984 and 2018, we have that:

Hence the rate is:

r = (173.50 - 250)/(2018 - 1984) = -2.25 thousand deer a year.

For item b, the situation is modeled by a linear function, as follows:

D(t) = 230.50 - 1.45t.

The population would be of 225 thousand deer when D(t) = 225, hence:

230.50 - 1.45t = 225

1.45t = 5.5

t = 5.5/1.45

t = 3.79.

Hence between the years of 2017 and 2018.

For item c, the rates are as follows:

Using the sample size relation with the standard normal distribution, the required sample size is 3032 samples.

What is Normal distribution ?

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

Using the sample size relation with the standard normal distribution, the required sample size is 673 samples.

n = [(Z* × σ) / ME]²

ME = margin of error

Z* = Z critical at 90% = 1.645

Substituting the values into the equation :

n = [(Z* × σ) / ME]²

n = [(1.645 × 50.2) / 1.5]²

n = (82.6/ 1.5)²

n = 55.06

n ≈ 3032

Therefore, the Number of samples required is 3032 samples.

To find the slope of a line that passes through two points, we can use the following formula:

Then, we have:

Line EF

Line GH

Now, when graphing the two lines, we have:

If two lines have equal slopes, then the lines are parallel. As we can see, their slopes are equal, therefore the lines EF and GH are parallel.

Line JK

Line LM

Now, when graphing the two lines, we have:

As we can see, the slopes of these lines are different, so they are not parallel. Let us see if their respective slopes have the relationship shown below:

Since their respective slopes do not have the relationship shown below, then the lines are not perpendicular.

Line NP

Line QR

Now, when graphing the two lines, we have:

Two lines are perpendicular if their slopes have the following relationship:

In this case, we have:

Since the slopes of the lines NP and QR satisfy the previous relationship, then this pair of lines are perpendicular.

Line ST

The line ST has an indefinite slope because it is not possible to divide by zero. Lines that have an indefinite slope are vertical.

Line VW

Line VW has a slope of 0. Lines that have a slope of 0 are horizontal.

Now, when graphing the two lines, we have:

As we can see in the graph, the ST and VW lines are perpendicular.

x represents the number of packages of coffee sold

y represents the number of packages of pastry sold

We were the cost of a package of coffee is $6 and the cost of a package of pastry is $4. If the total amount made from selling x packages of coffee and y packages of pastry is $72, then the equation representing this scenario is

6x + 4y = 72

Also, we were told that she sold 2 more packages of coffee than pastries. This means that

x = y + 2

Thus, the system of linear equations is

6x + 4y = 72

x = y + 2

We would plot these equations on the graph. The graph is shown below

The red line represents x = y + 2

The bu line represents x = y + 2
