the depth of the water, d, at the end of a pier changes periodically as a function of time, t, in hours as shown in the graph below. according to the model, the last low tide occurred at 5:00 a.m. when will the next low tide occur? let t = 0 be 12:00 a.m.

the depth of the water, d, at the end of a pier changes periodically as a function of time, t, in hours as shown in the graph below. according to the model, the last low tide occurred at 5:00 a.m. when will the next low tide occur? let t = 0 be 12:00 a.m.

Answer

Explanation:

Step1: Identify the period

The graph shows a periodic - function. The period is the time between two consecutive low - tides. By observing the graph, we can see that the period is 12 hours.

Step2: Calculate the time of the next low - tide

The last low - tide occurred at (t = 5) (5:00 a.m.). To find the time of the next low - tide, we add the period to the time of the last low - tide. So, (t=5 + 12=17). Since (t = 0) is 12:00 a.m., (t = 17) corresponds to 5:00 p.m.

Answer:

5:00 p.m.
