Q:
A ball is thrown from an initial height of 4 feet with an initial upward velocity of \( 31 \mathrm{f} / \mathrm{s} \). The ball's height \( h \) (in feet) after \( t \) seconds is given by the following.
\[ h=4+31 t-16 t^{2} \]
Find all values of \( t \) for which the ball's height is 18 feet.
Round your answer(s) to the nearest hundredth.
