Answer:
t = 2.11 seconds
Step-by-step explanation:
A toy rocket is launched from the top of a 48 foot hill. The rockets initial upward velocity is 32 feet per second and its height h at any given second t is modeled by the equation:

Let us assume that we need to find the time by it to reach the ground. It means h = 0

The above is a quadratic equation. The value of t is given by :

So, it will take 2.11 seconds to reach the ground.

Answer: HRP = 40°
Explanation:
Angle EPN = 40°
But EPN = HRP (corresponding angle)
Because EP//HR
Therefore EPN = HRP = 40°
