Part a: Option D 18 feet per second
Part b: increasing
Solution:
Height 
Part a: To find the average rate of change for h(t) between t = 0 and t = 2.
Substitute t = 0 in h(t).

h(0) = 3
Substitute t = 2 in h(t).
h(2) = 39
Average rate of change formula:

Here, a = 0 and b = 2.



= 18
Average rate of change = 18 feet per second
Option D is the correct answer.
Part b:
This means height of the ball is increasing for 0 < x < 2.
E(1,-4) F(1,-6) G(-3,-5) H(-3,-3)
Answer:
<u>David will have the most cookies and he will have two cookies more than Jake</u>
Step-by-step explanation:
1. Let's calculate how many cookies will David cut with his cutter, this way:
Number of cookies = Rolls of cookie dough/Size of the segment
Replacing with the values we know:
Number of cookies = 2/(1/8)
Number of cookies = 16
2. Let's calculate how many cookies will Jake cut with his cutter, this way:
Number of cookies = Rolls of cookie dough/Size of the segment
Replacing with the values we know:
Number of cookies = 2/(1/7)
Number of cookies = 14
<u>David will have the most cookies and he will have two cookies more than Jake</u>
