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 faithandchris2101732

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) Substitute 30 for th(30) = 150 - 120 Simplifyh(30) = 30

The person would be 30 feet above the ground in half an hour.  ### Other questions on the subject: Mathematics Mathematics, 21.06.2019, letsgetcookingblog Mathematics, 21.06.2019, ronaa
