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

<h3>How to Evaluate a Function?</h3>

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.

A flat rectangular piece of aluminum has a perimeter of 70 inches. The length is 11 inches longer than the width. Find the width
rodikova [14]

perimeter = 2L +2w

L = w+11

70 = 2(w+11) +2w

70 = 2w+22+2w

70= 4w + 22

48 = 4w

w=48/4 = 12

width = 12

length = 12+11 = 23

2x12 = 24

2x23 = 46

46+24 = 40

 length = 23 inches, width = 12 inches
