Transformations of Trig. Help functions, please, please, please, i use, i use, please answer seriously!?

1. A wind turbine uses rotating blades to produce electricity. The equation h (θ) = 8.5 sin (θ + 180) + 30 can be used to find the height, h (θ), in meters, of a point on a particular sheet, where θ is the angle of the blade with the horizontal. a) He tells each plot for the function of 0 <θ <720, tell each plot without drawn. b) Explain why the sine function model was used in the height of a point on one sheet.

The amplitude of the function is 8.5. This means that the sheet will be up to 8.5 meters from the center where sin is 1. The funny thing here is that even when the blade angle is 90 degrees, which is can wait until the end of the road is the highest, but sin (90 +180) = -1. This indicates that the point is in any lower section of the leaf. 30 is a displacement up the graph, so the point is never below 30-8.5, or 21.5 meters, and never goes above 30 8.5, or 38.5 meters. When θ = 0, the point is 30 meters. Then, the point enters a circle which means it is rhythmically rises and then falls as the sine function.
