The cost of making rubber duckies is CH, p, s) = l (p + s) where l is labor time, p is cost of parts, and s is the skill level of the workers. Due to a union agreement the labor is constrained by the skill level as follows: I2 + .92 =1 . Due to a supplier contract and “just in time manufacturing” philosophy at your company the parts and labor are inversely related lp =1 . Assuming you have complete control over labor, parts, and skill level of employees, minimize the cost of making rubber duckies. 6) Setup the integral in rectangular, cylindrical, and spherical coordinates for the integral of f(x, y,z) = 6 + 4y over the region in the ﬁrst octant bounded by the cone 2 Z = lez + y2 , the cylinder x2 + y2 =1, and the coordinate planes.
