6. Express as the limit of a Riemann sum. (2x 5x-2) dx 7. A rectangul vertical sides which run n ar region with area 4800 square feet is to be enclosed within a fence. The two orth-south will use fencing materials costing $2.00 per foot, while the zontal sides require fencing materials costing $5.00 per foot. Find the dimensions of the region which gives the minimum cost.
