Hey user
so it is 3
we round the 7 up so we get 2.70 and then we round that up to 3
The 80 is the height of the platform that the rocket is launched off of.
The general form of this function is
h(t) = -16t² + v₀t + h₀.
-16 represents the gravitational force. v₀ is the initial velocity the rocket is launched with. h₀ represents the initial height it is launched from.
The answer to this question is -61
