The grade resistance F of a car traveling up or down a hill is modeled by the equation F = W sin 0, where W is the weight of the car and e is the angle of the hill's grade (0 > 0 for uphill travel, 0 < 0 for downhill travel). Find the weight of the car (to the nearest pound) that is traveling on a -2.2° downhill grade and which has a grade resistance of -153.55 Ib. O 4300 Ib O 3800 Ib 4100 lb O 4000 Ib
