The blades of a windmill turn on an axis that is 35 feet above the ground. The blades are 10 feet long and complete two rotations every minute. Which of the following equations can be used to model h, the height in feet of the end of one blade, as a function of time, t, in seconds? Assume that the blade is pointing to the right, parallel to the ground at t = 0 seconds, and that the windmill turns counterclockwise at a constant rate. h = negative 10 sine (StartFraction pi Over 15 EndFraction t) + 35 h = negative 10 sine (Pi t) + 35 h = 10 sine (StartFraction pi Over 15 EndFraction t) + 35 h = 10 sine (Pi t) + 35
