Alabama Instruments Company has set up a production line to manufacture a new calculator. The rate of production of these calculators after t weeks is dx/dt=4000(1-100/(t+10)^2) calculators/week. (Notice that production approaches 4000 per week as time goes on, but the initial production is lower because of the workers' unfamiliarity with the new techniques.)
