Status: Waiting for your answers. Problem:Using factoring, determine how long an object stays in the air if its height is defined by these parametric equations.x(t) = 4ty(t) = -16t^{2} + 784 Work: -16t^{2} + 784 = 0 -16(t^{2} - ) = 0 -16(t - )(t + ) = 0 t - = 0 OR t + = 0 t = OR t = Solution:This object will stay in the air for seconds.

x(t) = 4ty(t) = -16t^{2} + 784
