12. A toy cannon ball is launched from a cannon on top of a platform. The function h(t) = -5t² + 15t + 10 gives the height, in meters, of the ball t seconds after it is launched. Write and solve an inequality to find the times where the ball is more than 21 meters above the ground. Round to the nearest hundredth. h(t) < = 5t² + (15)t - (1P 28 seconds
