Question 527930: Can someone please help me with this question, I just need the answer. I haven't been able to figure it out.
A model rocket is launched with an initial upward velocity of 105ft/s. The rockets height h (in feet) after t seconds is given by the following.
h=105t-16t^2
Find all the values of t for which the rocket's height is 34 feet.
Round your answer(s) to the nearest hundredth.

You can put this solution on YOUR website!
To find the answer, plug in h = 34 and solve for t.


Doing so gives us the solutions of

t = 0.34158988997028

t = 6.22091011002972


Note: these solutions are approximate


Now round each solution to the nearest hundredth to get the final answer of

t = 0.34

t = 6.22
