A defense contractor is starting production on a new missile control system. On the basis of data collected during the assembly of the first 16 control systems, the production manager obtained the function L'(x) = 2,600x -1/2 describing the rate of labor use. For example, after assembly of 16 units, the rate of assembly is 650 labor-hours per unit, and after assembly of 100 units, the rate of assembly is 260 labor-hours per unit. The more units assembled, the more efficient the process. If 20,800 labor-hours are required to assemble the first 16 units, how many labor-hours L(x) will be required to assemble the first x units? The first 100? In order to find L(x), take the indefinite integral of L' (x). take the derivative of L'(x)
