(a) A chemical manufacturer sells sulfuric acid in bulk at a price of $ 100 per unit. If the daily total production cost in dollars for x units is C x = 100 , 000 + 50 x + 0.0025 x 2 and if the daily production capacity is at most 7000 units, how many units of sulfuric acid must be manufactured and sold daily to maximize the profit? (b) Would it benefit the manufacturer to expand the daily production capacity? (c) Use marginal analysis to approximate the effect on profit if daily production could be increased from 7000 to 7001 units.

Use the method of disks to find the volume of the solid that is obtained
when the region under the curve y = over the interval [4,17] is rotated
about the x-axis.
3. Use the method of washers to find the volume of the solid that is obtained
when the region between the graphs f(x) = √√2 and g(x) = secx over the
interval ≤x≤ is rotated about the x-axis.
4. Use cylindrical shells to find the volume of the solid generated when the
region enclosed by the given curves is revolved about the x-axis.
y = √√x, y = 0, y = √√3
