1. A butterfly is clinging to the tip of one blade of a windmill. The center of the windmill is 30 feet above ground and has a radius of 8 feet. It takes the windmill 20 seconds to complete one revolution. The butterfly's path
begins in the 9 o'clock position and the blade rotates clockwise. Write an equation that can be used to calculate
the butterfly's height off of the ground at any time during the 'ride. Then use the equation to calculate its
height after riding for 17 seconds.
