Answer:
Step-by-step explanation:
The existence of a unit rate implies that you have TWO variables. Here you list only one: $.
If you pay $2.98 for 6 units of something, such as pieces of fruit, then the unit rate would be:
$2.98
----------------------- = $0.50/piece
6 pieces of fruit
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.
Answer:
k= -13
Step-by-step explanation:
-6k = -10 + 88
-6k = 78
k = -13
