Question

3. Alvin throws the football to a receiver who jumps up to catch the ball. The height of the ball over time can be represented by the quadratic equation -4.9t² + 7.5t + 1.8 = 2.1 . This equation is based on the acceleration of gravity-4.9 m/s², the velocity of his pass is 7.5 m/s and releases the football at a height of 1.8 meters, and the height where the receiver catches the ball of 2.1 meters. Put the equation in standard form and then solve by using the quadratic equation.

Answer 1

Set the equation equal to 0. Use the quadratic formula to solve. Its important you factor out the negative before you begin to factor the trinomial. Good luck.
