Wind-powered energy: If a wind-powered generator is delivering P units of power, the velocity V of the wind (in miles per hour) can be determined using , where k is a constant that depends on the size and efficiency of the generator. Given k = 0.004, approximately how many units of power are being delivered if the wind is blowing at 27 miles per hour?

Exercise 68

Wind-powered energy: If a wind-powered generator is delivering P units of power, the velocity V of the wind (in miles per hour) can be determined using , where k is a constant that depends on the size and efficiency of the generator. Rationalize the radical expression and use the new version to find the velocity of the wind if k = 0.004 and the generator is putting out 13.5 units of power.
