Modeling with Quadratic Equations Answers

Again, the quarterback throws the football, but this time the model y = –16x2 + 35x + 6.5 describes the height (y), in feet, of the football x seconds after it is thrown. If the ball is not caught, how long will it be in the air?0 = –16x2 + 35x + 6.5x = Rounded to the nearest tenth, the solutions of the equation are .

Which quadratic equation models the situation correctly?

To the nearest tenth of a second, the ball is in the air for s.
