Assume for this problem that the depth of the uwater at the Edmonds Pier is a sinusoidal function of time. A low tide of 5 feet occurs at 2:00am and a high tide of 21 feet occurs at 8:00am. (a) Use Desmos to approrimate the time(s) during a 24-hour period when the water is falling at the rate of 2 ft/hr. Include a screen shot and erplain your method. (b) Find all times during a 24-hour period when the water is falling at the rate of 2 ft/hour. Do not use a calculator. Give eract times. (c) Then, at the very end, ues a calculator to give the clock time(s), correct to the nearest minute. Compare with your estimate(s) from Desmos.

Question
Transcribed Image Text:Assume for this problem that
the depth of the water at the Edmonds Pier is a sinusoidal function of time.
A low tide of 5 feet occurs at 2:00am and a high tide of 21 feet occurs at
8:00am.
(a) Use Desmos to approximate the time(s) during a 24-hour period when
the water is falling at the rate of 2 ft/hr. Include a screen shot and explain
your method.
(b) Find all times during a 24-hour period when the water is falling at
the rate of 2 ft/hour. Do not use a calculator. Give exact times.
(c) Then, at the very end, ues a calculator to give the clock time(s),
correct to the nearest minute. Compare with your estimate(s) from Desmos.
