Ruby tosses a quarter off the main stree bridge into the st. john's river. the distance, in feet, the quarter is above the water is modulated by the equation d(t)= -16t^2+96t+112, where t represents time in seconds.
part a: from what height was the quarter tossed?
part b: how long does it take the quarter to reach its maximum height?
part c: what is the maximum height of the quarter?
part d: how much time does it take for the quarter to hit the water?
