Answer:

30 feet

Step-by-step explanation:

Hello!

Half an hour is 30 minutes, so that means we are asked to find h(30).

Solve for h(30):

  • h(30) = 150 - 4(30)         [tex]\implies[/tex] Substitute 30 for t
  • h(30) = 150 - 120           [tex]\implies[/tex]  Simplify
  • h(30) = 30

The person would be 30 feet above the ground in half an hour.

Answer:

30 ft

Step-by-step explanation:

Half an hour is equivalent to 30 minutes.

Thus, h(t) = 150 - 4t becomes h(30 min) = 150 ft - 4(ft/min)(30 min) = 30 ft
