Phileas is going on a hot air balloon ride. His height above the ground after t minutes is a quadratic function of t. He begins from a platform at a height of 76 meters. The balloon reaches its maximum height after 30 minutes. After 80 minutes, he finally lands (at a height of 0 meters).

COMPLETE QUESTION:

Phileas is going on a hot air balloon ride. His height above the ground

after t minutes is a quadratic function of t.

He begins from a platform at a height of 76 meters.

The balloon reaches its maximum height after 30 minutes.

After 80 minutes, he finally lands (at a height of 0 meters)

(a) Give a function f(t) for Phileas’s height above the ground after t minutes.

f(t) = (-76/160)t² + (9560/1600)t + 76
