If a person's eye level is h meters above sea level and he can see d kilometers to the horizon, then d = 3.57 h. Suppose the person's eye level is 2.25 meters above sea level. How far can he see to the horizon? Round your answer to the nearest tenth. 22. Suppose that a wave forms in shallow water. The depth d of the water (in feet) and the velocity v of the wave (in feet per second) are related by the equation v = 32d. If a wave forms in water with a depth of 4. feet, what is its velocity? Round your answer to the nearest tenth. ALEKS HW 22 - Section 7.5 # - 05/25/206 09:03 AM EDT - Copyright 206 UC Regents and ALEKS Corporation. P. 4 /

What is the height of his eye level above sea level? Carry your intermediate computations to at least four decimal places, and round your answer to the nearest tenth. 24. Suppose that a wave forms in shallow water. Then the depth d of the water (in meters) and the velocity v of the wave (in meters per second) are related by the equation v = 9.8d. If a wave formed in shallow water has a velocity of 4.5 meters per second, what is the water's depth?
