1. Mark Twain sat on the deck of a river steamboat. As the paddlewheel turned, a point on the paddle blade moved in such a way that its distance, d, from the water's surface was a sinusoidal function. When his stopwatch read 5 seconds, the point was at its highest, 16 feet above the water's surface. The wheel's diameter is 18 ft and it completes one revolution every 10 seconds. a. Sketch 2 periods of the graph of this function. b. Write the equation of the sinusoid. c. Use your equation to find the distance from the surface of the water after 28 seconds.
