Answer by stanbon(57214)   (Show Source): You can put this solution on YOUR website!A roasted turkey is taken from an oven when its temperature has reached 185oF and is placed on a table in a room where the temperature is 75oF. ----- You have 1 point relating time and temperature: (0,185) a) If the temperature of the turkey is 150oF after half an hour, what is its temperature after 40 min? You now have a 2nd point relating time and termperature: (30,150) ----- Find the equation relating time and temp: intercept = 185 slope + (185-150)/(0-30) = -35/30 = -7/6 ---- Equation: f(t) = (-7/6)t+185 what is its temperature after 40 min? f(40) = (-7/6)(40)+185 = 138.33 degrees Farenheit ------------------------------- b) When will the turkey cool to 90oF? 90 = (-7/6)t+185 (-7/6)t = -95 t = 85.43 minutes ==================== Cheers, Stan H. ====================
