Duration: 50 min. Be neat, show your work to receive credit. 1 (5 points) The tank shown below is full of water. Set up (do not compute!) a definite integral representing the work required to pump the water out of the spout. Note that the density of water is 1000 kg/m3 and the constant g of gravity is 9.8 m/s2 yן 6m 8m -3m I х frustum of a cone 2 (5 points) Let S be the solid obtained by rotating the region bounded by y = x3, y2 = x about the vertical line y = 2. (a) Using the washer method set up (do not compute!) an integral expressing the volume of solid S. I (b) Using the method of cylindrical shells set up (do not compute!) an integral expressing the volume of solid S. [ 3 (5 points) Find the volume of the solid below by integrating the area of cross-sectional regions. I 2 cm 4 cm 3 cm X 4 (5 points) Find the centroid (x,y) of a lamina (with uniform density) bounded by the x-axis, y-axis and ellipse x2 + 1, pictured below. Note that the area of the lamina here is 3A/2. 4. 9 y2 = V 3 х 2 5 и (5 points) Solve x everyone + y = e-3x with y(1) = 0 for y(x). Hint: Let y and first solve for u. х 6 (5 points) A tank contains 200 L of pure water. Brine that contains 0.08 kg of salt per liter of water enters the tank at a rate of 6 L/min. The solution is kept thoroughly mixed and drains from the tank at a rate of 6 L/min. How much salt is in the tank after one hour? 7 (5 points) The line segment x = 1, y ,0 < y
