 Click here to see ALL problems on Expressions-with-variables Question 108753This question is from textbook : Under certain conditions, the power P, in watts per hour, generated by a windmill with winds blowing v miles per hour is given by P(v)= 0.015v^3 a) find the power generated by 15-mph b) how fast must the wind blow in order to generate 120 watts of power in one hour? I put in 15 for x on the first part. second part I left the equation solved for a and divided by 120. I don't think this resulted the correct answers, help.This question is from textbook Answer by stanbon(57387)   (Show Source): You can put this solution on YOUR website!the power P, in watts per hour, generated by a windmill with winds blowing v miles per hour is given by P(v)= 0.015v^3 a) find the power generated by 15-mph P(15) = 0.015v^3 = 0.015(15^3) = 50.625 watts ------------------------- b) how fast must the wind blow in order to generate 120 watts of power in one hour? 120 = 0.015v^3 120/0.015 = v^3 v = 20 mph ============= Cheers, Stan H.
