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.
The mean is the average of the numbers. to find the mean add up the numbers and divide by how many numbers there are
