The rise would have to be 12.
This is because in order to be "Similar" triangles the sides need to be proportionate.
(1/3 = 4/12)
Answer:
As it sounds, the idea itself.
Step-by-step explanation:
Answer:
(B)
Step-by-step explanation:
we know that standard equation of parabola y²= 4x or x² = 4y .
So option (B) is correct .

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.
