Sketch the graph through at least one complete cycle. Label the axes on the coordinate plane. Use your graph to predict the height of point P above the surface of the water when the stopwatch shows 7 seconds. Round to the nearest tenth of a foot. (Enter only the number.)

To sketch the graph and make the prediction, we need some information about the problem that you haven't provided. Specifically, we need to know the nature of the graph and the relationship between time and the height of the point P above the surface of the water. It seems that you are referring to a periodic motion, possibly involving waves or some kind of oscillation.
Please provide additional information about the nature of the graph or the equation that describes the relationship, so that I can assist you in sketching the graph and making the prediction.
