Math Problem Statement
A projectile is fired from a cliff 190190 feet above the water at an inclination of 45° to the horizontal, with a muzzle velocity of 50 feet per second. The height h of the projectile above the water is given by h(x)=−32x^2/ (50)^2+x+190 (a) At what horizontal distance from the face of the cliff is the height of the projectile a maximum?
