Answer:
3.50+0.125m(0.23) = C
Step-by-step explanation:
Initial fee- $3.50
Each 1/8 mile costs $0.23
total cost = C
1/8 = 0.125
3.50+0.125m(0.23) = C
Here is the order
- 6 2/3 ,- 1.3 , 29/8 , 7
Answer:
Numer 1
A) (-5, -4), (-4, -3), (-3, -2), (-2, -1) Is a function
Number 2
C) (-5, -1), (-2, -1), (1, -1), (4, -1) is a function
Part A:
The average rate of change refers to a function's slope. Thus, we are going to need to use the slope formula, which is:

and
are points on the function
You can see that we are given the x-values for our interval, but we are not given the y-values, which means that we will need to find them ourselves. Remember that the y-values of functions refers to the outputs of the function, so to find the y-values simply use your given x-value in the function and observe the result:




Now, let's find the slopes for each of the sections of the function:
<u>Section A</u>

<u>Section B</u>

Part B:
In this case, we can find how many times greater the rate of change in Section B is by dividing the slopes together.

It is 25 times greater. This is because
is an exponential growth function, which grows faster and faster as the x-values get higher and higher. This is unlike a linear function which grows or declines at a constant rate.
2) 1 4/5
3) 2
4) 4 1/3
5) 3 4/8 or 3 1/2
6) 6 2/8
