SOLUTION: A launched rocket has an altitude, in meters, given by the polynomial h+vt-4.9t^2,where h is the height , in meters, from which the launch occurs, at velocity v in meters per secon

Question 741339: A launched rocket has an altitude, in meters, given by the polynomial h+vt-4.9t^2,where h is the height , in meters, from which the launch occurs, at velocity v in meters per second, and t is the number of seconds for which the rocket is airborne. If a rocket is launched from the top of a tower 50 meters high with an initial upward speed of 30 meters per second, what will its height be after 2 seconds?
its height will be ___ meters
(round to the nearest tenth)

H=h+vt-4.9t^2
plug in 50 for small h
2 for t
30 for v
H=h+vt-4.9t^2
H=50+30*2-4.9*(2^2)
H=50+60-4.9*4
H=110-19.6
H=90.4 meters
