Question

Please help. A skyrocket is launched from a 6 foot high platform with initial speed 200ft/s. The polynomial -16t^2 + 200t + 6 gives the height in feet the skyrocket will rise in t seconds. How high will the rocket rise in 6 seconds

Answer 1

630 if i typed it in the calc correctly lol

Answer 2

The height of the rocket after 6 seconds is 630 feet

Functions and values

Given the polynomial function that represents the height of the rocket expressed as:

f(t) = -16t^2 + 200t + 6

If the time the rocket take to rise is 6 seconds, hence;

f(6) = -16(6)^2 + 200(6) + 6

f(6) = - 576 + 1200 + 6

f(6) = 630 feet

Hence the height of the rocket after 6 seconds is 630 feet
