Answer:I think its the second one
Step-by-step explanation:
A) use a straightedge to draw a line thought D and F
Using the given table:
a) the average rate of change is 32.5 jobs/year.
b) the average rate of change is 12.5 jobs/year.
<h3>
How to find the average rate of change?</h3>
For a function f(x), the average rate of change on an interval [a, b] is:
![\frac{f(b) - f(a)}{b - a}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29%20-%20f%28a%29%7D%7Bb%20-%20a%7D)
a) The average rate of change between 1997 and 1999 is:
![A = \frac{695 - 630}{1999 - 1997} = 32.5](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B695%20-%20630%7D%7B1999%20-%201997%7D%20%20%3D%2032.5)
So the average rate of change is 32.5 jobs/year.
b) Now the interval is 1999 to 2001.
The rate this time is:
![A ' = \frac{720 - 695}{2001 - 1999} = 12.5](https://tex.z-dn.net/?f=A%20%27%20%3D%20%5Cfrac%7B720%20-%20695%7D%7B2001%20-%201999%7D%20%3D%2012.5)
So the average rate of change is 12.5 jobs/year.

Answer: $42.56
Step-by-step explanation:
Percent discount in department store = 38%
The regular price of suit = $112.
Price taken off the regular price of the suit =
38% of $112
So, 38% of $112
= (38/100) x $112
= 0.38 x $112
= $42.56
(i.e the customer will pay $112 - $42.56 = $69.44 only for the suit)
Thus, the price taken off the regular price of the suit is $42.56
Answer:
Let's say 50
Step-by-step explanation:
40% of 100 is 40
50% of 117 is about 59
so number should be a somewhere in between.
