Answer:

  • 5184 ft

Step-by-step explanation:

Given

A quadratic function

  • h(t)= -16t^2+480t+1584.

Its maximum is its vertex

Vertex formula for ax^2 + bx + c is

  • x = -b/2a

Applying this to our function

  • t = -480/2(-16) = 15

Maximum height is reached after 15 seconds and is

  • h(15) = -16*15^2 + 480*15 + 1584 = 5184 ft
