Which of the statements is true?

A. For every value of x, the rate of change of f(x) exceeds the rate of change of g(x).

B. As x increases, the rate of change of g(x) exceeds the rate of change of f(x).

C. At approximately x = 4.74, the rate of change of g(x) is equal to the rate of change of f(x).

D. As x increases, the rate of change of f(x) exceeds the rate of change of g(x).

Answers

A statement that is true include the following: B. As x increases, the rate of change of g(x) exceeds the rate of change of f(x).

How to determine the average rate of change?

In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by this mathematical expression:

Average rate of change = [f(b) - f(a)]/(b - a)

Next, we would determine the average rate of change of the function f(x) over the interval [0, 1]:

a = 0; f(a) = 1

b = 1; f(b) = 6

By substituting the given parameters into the average rate of change formula, we have the following;

Average rate of change = (6 - 1)/(1 - 0)

Average rate of change = 5/1

Average rate of change = 5

For g(x), we have the following:

Average rate of change = (216 - 0)/(1 - 0)

Average rate of change = 216/1

Average rate of change = 216

and 4 divided by 4. so its 7/1 which just equals 7. please correct me if im wrong good luck.

Hey there!

In order to solve for this particular question that you have asked.. we can just simply divide 28 from 4

Equation: 28 / 4

28 ÷ 4 / 4 ÷ 4

28 ÷ 4 = 7

4 ÷ 4 = 1

New equation: 7 / 1

Simply the newer equation and you have your answer

7 ÷ 1 = 7 / 1 ➡️ 7

Answers

The first question the answer is 15.
This happens because 2×8 = 16. After that you multiply 16 by half. What do you do that the answer is eight then you add seven and get 15.

For the second question you do -6 times negative one. After that you’ll get six. Then you would have to multiply it by -2 and get -12. Then you add -12+3 and then you get -9. Your answer is -9


For the third question you would add 7+3 and get 10. Then you would have to multiply it to the second power and get 1000. Then you would have to add 1000 with four. Then you multiply seven by -2 and multiply that by four. Then you would get -56
Your answer would be -56.

Step-by-step explanation:

1/2 times 2 times 8 + 7      #2:-2(-1)(-6)+3                   #3:  (7+3)^2 +4(7)(-2)

1/2 times 2 = 1                           -2times -1=2                                 (10)^2 +4(7)(-2)

1 times 8= 8                              2(-6)+3                                           100+4(7)(-2)

8+7=15                                     2times -6=-12                                   100+28(-2)

A trapezoid has a height of 10 feet, and base measurements of 20 feet and 8 feet. What is the area?

The answer must be in square feet

Answers

Answer:Therefore, the area of the trapezoid

Step-by-step explanation
To find the area of a trapezoid, you can use the formula: A = 1/2 * (b1 + b2) * h, where b1 is the length of the longer base, b2 is the length of the base, and h is the trapezoid's height.

In this case, the longer base (b1) is 20 feet, the shorter base (b2) is 8 feet, and the height (h) is . We obtain the following result as soon as we insert these values into the formula:
A = 1/2 * (20 + 8) * 10
A = 1/2 * 28 * 10
A = 140 square

How is an exponential growth function of the form ​f(x)=a(1+r)^x related to an exponential function of the form ​f(x)=a*b^x?
A.
The value of a is the growth​ factor, and b is equal to the initial amount r.
B.
The value of a is the growth​ factor, and b is equal to the initial amount ​(1+​r).
C.
The value of a is the initial​ amount, and b is equal to the growth factor ​(1+​r).
D.
The value of a is the initial​ amount, and b is equal to the growth factor r.

Answers

The true statement is (c) the value of a is the initial​ amount, and b is equal to the growth factor ​(1+​r).

How to compare the functions?

The functions are given as:

f(x) = a(1 + r)^x

f(x) = a * b^x

An exponential growth function is represented as:

y = ab^x

Where

a represents the initial valueb represents the rate

By comparison:

b = 1 + r

Hence, the true statement is (c) the value of a is the initial​ amount, and b is equal to the growth factor ​(1+​r).
