PLEASE HELP ME! easy task seventh grade in math?
a golf ball is hit from the ground, and its height, h, in feet above the ground is modeled by the funstion, h (t) =- 16t ^ 2 200 t, where t represents time in seconds after the ball is beaten. How long is the ball in the air? and one more question: what can be used to solve the equivalent equation 20x-25x -4 + ^ 2 = 0? a) -1 (2-5x) ^ 2 = 0, b) -1 (2 +5 x) ^ 2 = 0, c) (2-5x) (2 = 5x) = 0, d) -1 2 (-5x) (2 +5 x) = 0 If you can show me how you did, that would be great! THANKS!
The ball is in the air at t = 0 (ie h (t) = 0) when h (t) = 0 again. h (t) =- 16t ^ 2 + 0 = 200t-16t ^ 2 + 200 tt (16t - 200) = 0 t = 0 t = 200/16 = 12.5 s Therefore, t = 12.5 - 0 = 12.5 s ^ 2 25x - 20x + 4 = 0 (5x - 2) ^ 2 = 0 Option D.
