A ball is thrown from an initial height of 4 feet with an initial upward velocity of 28 ft/s. The ball's height h (in feet) after t seconds is given by the following.
h=4+ 281 – 1612
Find all values of t for which the ball's height is 12 feet.
Round your answer(s) to the nearest hundredth.

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x? y? z? , with vertices x? (4, -2), y? (4, -3), and z? (1, -4). the type of transformation that triangle xyz undergoes is a . triangle x? y? z? then undergoes a transformation to form triangle x? y? z? , with vertices x? (4, 2), y? (4, 3), and z? (1, 4). the type of transformation that triangle x? y? z? undergoes is a .
