Use a Riemann sum with n=2 rectangles to estimate the area under the curve f(x) =3x2 +1 on the interval between x = 1 and x = 5. Get the heights from the left hand sides. What is the value of this Riemann sum? It has been determined that the cost of producing a units of a certain item is 5x + 325. The price per item is related to x by the equation p = D(x) = 50 -...
