Amodel rocket is launched with an initial upward velocity of 73 m/s . the rocket's height (in meters) after t seconds is given by the following.
h= 73t-5t^2
find all values of t for which the rocket's height is 47 meters. round your answer(s) to the nearest hundredth.

13.71 and 0.69

Step-by-step explanation:

Set 73t-5t^2 equal to 47 and solve

-5t^2 + 73t - 47 = 0

Quadratic formula

(-73 +- sqrt(4389))/-10

x = 13.92 or x = 0.68
