To determine the size of the motor required to operate a press, a company must know the amount of work done when the press moves an object linearly 5 feet. The variable force to move the object is F(x) = 100x125 - x, where F is given in pounds and x gives the position of the unit in feet. Use Simpson's Rule with n = 12 to approximate the work W (in foot-pounds) done through one cycle when W = -6 5 F(x) dx- (Round your answer to two decimal places.) W= ft-lb
