(1 point) Suppose that the density of cars (in cars per mile) down a 20-mile stretch of the Pennsylvania Turnpike is approximated by 8(x) = 250 (2 + sin(4Vx+ 0.175)), at a distance x miles from the Breezewood toll plaza. Sketch a graph of this function for 0 < x < 20. (a) Complete the Riemann sum that approximates the total number of cars on this 20-mile stretch (use Dx instead of Ax): Number = Σ (b) Find the total...
