(1 point) A rod has length 4 meters. At a distance x meters from its left end, the density of the rod is given by 5(x) = 1 + 8x g/m. (a) Give a Riemann sum for the total mass of the rod (use Dx in place of A.x): Masa - Σ (b) Convert the Riemann sum to an integral and find the exact mass of the rod. Mass (include units)
