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 rotation
s 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
Based on these data, are "being female" and "earning over
$50,000" independent events. They are independent events because by being
female does not mean they could earn $50,000. It would depend on how the
females work their way to earn that kind of money.
