The Depth of Water (in mt 0 2 B 6 8 10 12 14 16 18 20 22 24 Time of the Day (in hours), t . ldentify the function relationship between the depth of water D and the time of the day t from the given graph above. Interpret the characteristics of this relation in the context of the problem. (Assessing Communication and interpretation) . Predict the relationship of the rate of change of the depth of water D and the time of the day. Explain how you may use the graph to construct data sets to analyze the relationship of this relationship. (Assessing Assumptions/Application/Analysis). Evaluate dD/dt fort =4 and t = 8, then interpret the meaning of these values in the context of the problems. . Suppose the depth of water D is modeled by the following equation: D(t) = 3.473 + 1.578 cos (%) Determine dD/dt. Calculate dD/dt at t = 4 and t =20 and compare them with the estimation in part (b). Graph the dD/dt and D on the same graph and explain the relationship between these two curves. (Assessing Representation/Calculation)
