A human cannonball is an act where a performer is launched through the air. The height of the performer can be modeled by h(x)=−0.004x^2+x+19, where ℎ is the height in feet and is the horizontal distance traveled in feet. The circus act is considering a flight path directly over the main tent. If the performer wants at least 5 ft of vertical height clearance, how tall can the tent be? Round your answer to the nearest foot.
