A ball was tossed up into the air. The height of the ball as a function of the time the ball is in the air in seconds can be modeled by a quadratic function. At the time the ball was initially thrown in the air, it was 7.5 meters off the ground. After 1.25 seconds, the ball was at its maximum height of 15.3125 meters. What was the height of the ball 2 seconds after being thrown? Round your answer to the nearest tenth as needed.
