To conduct an experiment, Jennifer throws a water balloon from the roof of a building. The path that the balloon follows is given by h(t) = -4.9t2 + 2t
+ 45, where t is the time, in seconds, after the balloon is thrown and his
the balloon's height, in meters, above the sidewalk below. State h(t) in
vertex form. What is the maximum height of the balloon, to the nearest
tenth of a meter. *
