Aball is projected upward from the top of a 90-foot building at a velocity of 64 feet per second. the ball's height above the ground below the building is described by the function h(t)=-16t^2+64t+90, with t being the time in seconds after the ball is projected upward.
a) determine the amount of the vertical intercept, and interpret what this means in the context of the problem(in terms of seconds and feet above the ground).
b)determine the numerical value of all horizontal intercepts (if any), and interpret what they mean in the context of the problem (in terms of seconds and feet above the ground).
c)write the coordinates of the vertex. interpret what these numbers mean in the context of the problem.
d)if nothing stops the ball before, then how much time elapses until the ball hits the ground below the building?
