4. a) Determine the average water depth during one tidal cycle.
b) Determine the period of the tidal cycle.
c) Determine a sinusoidal equation, of the form D=asin b(t-e) +d, that
models the water depth, D, in m, over time t, in hours.

Transcribed Image Text:The alternating cycles of the rise and fall of the ocean are called tides. Tides in one
section of the harbor in the Bay of Fundy caused the water depth to vary.
The maximum water depth occurs at (3, 17.5) and the minimum water depth occurs
at (9, 4.5).
