- Suppose P(x) represents the profit on the sale of x Blu-ray discs. If P(1,000) = 2,000 and P'(1,000) = -3, what do these values tell you about the profit? %3D %3D P(1,000) represents the profit on the sale of Blu-ray discs. P(1,000) = 2,000, so the profit on %3D the sale of Blu-ray discs is $ . P'(x) represents the ---Select---- O as a function of x. P'(1,000) = -3, so the profit is decreasing at the rate of per additional Blu-ray disc sold. %24arrow_forwardƒ (*¹-8x+√¹) dxarrow_forward7. Find the value of “a” if (x2/3)(x1/4) = xaarrow_forward

Suppose that the government imposes a $1000-per-day tax on the bicycle manufacturer so that the daily cost C of manufacturing x bicycles is now given by C(x) = 80x + 6000. Now the average daily cost C is given by C(x) = 80x + 6000/x . How many bicycles must be produced each day for the average cost to be no more than $100?arrow_forward
