The depth of water at a beach changes every 12 hours because of the tides. This forms a periodic function. You get up early on one of the days of spring break and start measuring the depth. The depth at 8AM (t=0)is 7 feet, which is a high point. The low at 2PM is 1 foot deep. According to your model, determine the height of the tide at 5PM. (Give the VALUE only. Do not include the unit of measurement in your answer.)
