During high tide around 11:00 p. m., the water level is 3 feet above a marker on a pier. The following day, during low tide around 5:12 a. m., the water level has dropped 3 feet below the marker. The height of the water is modeled by the function y = 3 cosine (StartFraction 24 pi Over 149 EndFraction x), where x is the time in hours since 11:00 p. m. What is the height of the water at 2:15 a. m.?
