1. Solve the inequality 2x2 - 8 50. 2. A ball is thrown into the air. The path it takes is modeled by the equation: -3t2 + 24t = h, where t is the time in seconds and h is the height of the ball above the ground, measured in feet. Write an inequality to model when the height of the ball is at least 36 feet above the ground. For how long is the ball at or above 36 feet
