Astuntman jumping off a 20-m-high building is modeled by the equation h=20-5t^2, where t is the same in seconds. a high-speed camera is ready to film him between 15m and 10m above the ground. for which interval of time should the camera film him?

Solve each equation using the quadratic formula. find the exact solutions. 6n^2 + 4n - 11
