Part 1:

Question

A missile is shot upward from a submarine 1440 feet below sea level at an initial velocity of 528 ft/sec. A function that approximates the height of the missile (relative to sea level) is given by:

h(t) = -16t^3 + 528t - 1440

where h(t) is the height of the missile in feet and t is the time in seconds.

Complete the table below to determine the height of the missile for the given values of time, t.

time (t)
0=
5=
15=
25=
35=

Part 2:
Using the same steps as you followed in the first question of this case study, find the time required for the missile to emerge from the water and the time required for the missile to reenter the water. Start your factorization by taking out the GCF.

Answer 1

Your equation should say
h(t) = -16t^2 + 528t - 1440 , not cubed
Besides that, it would have that function only after it leaves the water.
It would be different in the water.

So I will let you fix that
