C - The demand function for a particular product is given by D(x) = 24 - .6x – .03x2. If xo = 10 units ,find the consumer surplus for this product. [6] D-A defense contractor is starting production on a new missile control system. On the basis of data collected while assembling the first 16 control systems, the production manager obtained the following function for rate of labor use: 2400xz ,where g(x) is the number of labor-hours required to assemble the xth unit of a control system. What is the net change in labor-hours required to assemble the 16th to 25th control units? [5] g(x) = E - Find the area of the region bounded by y=r3 - 4x2 + x + 6 and the x-axis over (0,3). [7]

What is the net change in labor-hours required to assemble the 16th to 25th control units? [5] E- Find the area of the region bounded by y= x3 - 4x² +2 +6 and the x-axis over [0,3]. [7] F - Find the area enclosed by the curves y=x2 - 1 and y = 1 - x. [7] G - Find the volume of the solid formed by revolving the region below the curve y= V1+x- over (0,3) about the x-axis. (use the disk method) [7]
