Final Jeopardy
Answer
Final Jeopardy Music
Given the following Scenario: Suppose that the length of time between consecutive high tides is approximately 10.5 hours. According to the National Oceanic and Atmospheric Administration, on Saturday, August 23, 2008, in South Padre Island, Texas, high tide occurred at 2:45 AM (2.75 hours) and low tide occurred at 8:04 AM (8.067 hours). Water heights are measured as the amounts above or below the mean lower low water. The height of the water at high tide was 9.3 feet, and the height of the water at low tide was -0.9 foot. Write a sinusoidal function for the situation above.
