The velocity of water that flows from an opening at the base of a tank depends on the height of water above the opening. The function v(x) = 2gr models the velocity, v, in
feet per second. Given that g represents the acceleration due to gravity (32 ft/sec) and x
represents the height of the water in feet, find the depth of the water when the flow is 40
feet per second. Round your answer to the nearest tenth if necessary.
