The depth of low tide is 4 meters. The equation of the function is h(t) = 6cos- 2 7 (t - 2.5 ) + 10 where h(t) is the height of the water, t 16.8 hours after midnight. Time is represented as a decimal [2.5 is two and one half hours after midnight, so 2:30 am] Show the graph of this function in an appropriate window on the T184 calculator for a 24 hour day. At what time will the depth of the water be 14 meters for the second time after midnight? What will the depth of the water be at 8:15 am? Time water is 14 m for 2nd time after midnight: 1 mark Depth of water at 8:15 am: 3 marks 1 mark
