Urgent
the depth of water in the port at hinchinbrook is given by: d(t)= 2.6 sin (pi over 6 t) + 13.1, where d is in meters and t is the number of hours since high tide.
use the model to determine how many hours are there between high tides.
if high tide was at midnight, draw a graph to determine during which hours should it be safe for the boats to be in the port and between which hours they would have to stay away from the port. justify answers mathematically
