= Question Help A projectile is fired from a cliff 190 feet above the water at an inclination of 45° to the horizontal, with a muzzle velocity of 45 feet per second. The height h of the projectile above the water is given by -32x? h(x)= +x+190 (45)2 where x is the horizontal distance of the projectile from the face of the cliff. Use this information to answer the following. (a) At what horizontal distance from the face of the cliff is the height of the projectile a maximum? x = feet (Simplify your answer.)
