The height of the tide in the Bay of Fundy, relative to a pier, varies from a low of 4.5 m
at 02:08 AM to a high of 17.3 m at 08:21 AM
a.) Write a sinusoid to model the situation
b.) Determine the height of the tide relative to the pier at 11:30 AM.
Give your answer to the nearest 0.1 m.
c.) A boat needs a depth of at least 12 m to dock at the pier. Use a graphical approach
to determine when the boat is able to dock and when it must leave, during the course of
this day
