On a windmill, the tip of one blade moves in a circular motion. the maximum height is 18 feet and the minimum height is 4 feet. the height of the tip of the blade (in feet) can be modeled by the function h(x)=−14sinx+18 h(x)=−14sinx+18 where x is time in seconds. use the inverse function to determine how many seconds it will take to make a full rotation for one blade. a 0.3 second b 0.6 second c 1.6 seconds d
