1. The problem statement, all variables and given/known data The height, h, in metres, of the tide in a given location on a given day at t hours after midnight can be modelled using the sinusoidal function h(t)= 5 sin 30 (t-5) + 7 (A) find max and min value for depth of water. (B) what time is high tide? What time is low tide? (C) what is the depth of the water at 9:00am? 2. Relevant equations 3. The attempt at a solution (A) The maximum would be 12 because 5 + 7. The minimum would be 2 because 7-5. However when it comes to questions b and c I have no idea what to do or where to even begin.
