The number of seconds it takes for the waste to hit the ground for the given function is: 5 seconds.

How to Evaluate a Function?

We are given the function of height to time as, h(t) = -16t² + initial height, and we have the following:

• h(t) = 0 (height of the ground is 0)
• t = seconds the waste takes to height the ground
• Initial height = 400 feet

Plug in the values into the equation of the function

0 = -16t² + 400

Solve for t

0 - 400 = -16t²

-400 = -16t²

-400/-16 = t²

400/16 = t²

√(400/16) = t

20/4 = t

5 = t

t = 5

The number of seconds it takes is: 5 seconds.
