At present, a firm is manufacturing 2000 items. It is estimated that the rate of change of production P w.r.t. additional number of workers x is given by `(d P)/(dx)=100-12sqrt(xdot)` If the firm employs 25 more workers, then the new level of production of items is (1) 3000 (2) 3500 (3) 4500 (4) 2500

Differentiate the functions given w.r.t. x: sqrt(((x-1)(x-2))/((x-3)(x-4)(x-5)))

Let 'p' be the price per unit of a certain product, when there is a sale of 'x' units. The total revenue function is : P(x)=(100x)/(3x+1)-4x. (i) Find the marginal revenue function, rate of change of total revenue function with respect to x. (ii) When x = 10, find the relative change of revenue R, i.e., Rate of change of R with respect to x and also the percentage rate of change of R at x=10.
