A ball is thrown vertically upward into the air. If the ball

A ball is thrown vertically upward into the air. If the ball started from a height of 85 feet off the ground, use the following formula to represent the projection of the ball H =- 16 +32t + 185 where H is the height of the ball after t seconds have passed. Based on this information, answer the following questions. 1) When does the ball reach its maximum height? Your answer must be expressed as a decimal rounded to 2 decimal places with correct units. Hint: The maximum occurs at the vertex of the parabola. 2) What is the maximum height of the ball? Your answer must be expressed as a decimal rounded to 2 decimal places with correct units. 3) When does the ball return to the ground? You must use the quadratic formula to solve this problem. Your answer must be expressed as a decimal rounded to 2 decimal places with correct units. Hnt: The ball reaches the ground when the height equals zero.
