What is the correct order of the functions from least to greatest according to the average rate of change on the interval from x = 0 to x = 4?

Answers

To get the average rate of change, we simply have to use this formula:
ARC = (y2 -y1) / (x2 - x1)

For the first function:
ARC = (64 - 0) / (4 - 0) = 16

For the second function, since it's a line, the ARC would just be equal to the slope
m = ARC = (-1 - 0) / (0 - (-2)) = -0.5

For the third function:
h(0) = 18
h(4) = 66
ARC = (66 - 18) / (4 - 0) = 12

Therefore, the order of the functions from lest to greatest according to the average rate of change on the interval from x= 0 to x = 4 is:
g(x)
h(x)
f(x)

Answer:

the answer for my flvs students is g(x), h(x), f(x)

How to find the value of this expression

Answers

32 because 64 divided by 2 equals 32

The square root is 64 is 8. Then times that by 2 your answer is 16. Hope that helps.

If I make $7.25 a hour and I work for three days how much money is that every two weeks

Answers

There are a couple of things you didn't mention.
In order to come up with an answer to the question,
I have to assume reasonable numbers for them, and
then answer the question that I have invented.

Assumption #1: Each day that you work, you work for 8 hours.

Assumption #2: You work for three days each week.

If those assumptions are true, then you earn

($7.25 / hour) x (8 hours/day) x (3 days/week) x (2 weeks) =

($7.25 x 8 x 3 x 2) = $348 before taxes and other deductions.

I am pretty sure it would be $43.50 every two weeks because $7.25 x 3 is 21.75 and then for two weeks add 21.75 +21.75
