Answer:
95.
Step-by-step explanation:
2.85 times 10⁶=2850000
then 2850000÷30,000=9.5
so either 95 or 9.5
Which one sounds correct should be.
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:
2.5 pounds per book
Step-by-step explanation:
Set up a proportion
20 copies / 50 pounds = 1 copy / x pounds
Cross multiply
20x = 50
Divide both sides by 20
x = 2.5 pounds

Answer:
x = 1.5
Step-by-step explanation:
We just have to find the x-coordinate of the point of intersection between the two functions. From the graph, they intersect at (1.5, 2) so the answer is 1.5.
