2. Mark Twain sat on the deck of a river steamboat. As the paddlewheel turned, he noticed a dead fish caught on one of
the paddles. As the wheel turned, the distance, d, that the fish was from the water's surface was a sinusoidal function
of time. When his stopwatch read 4 seconds, the fish was at its highest, 16 feet above the water's surface. It took
another 10 seconds before the fish reached that height again. The diameter of the wheel was 18 feet.

Sketch a graph.
b. Write an equation. Show work to support your answer.
C.
How far above the surface was the point when Mark's stopwatch read: 17 seconds. Show work to support your
answer
