The equation p(x)= −40?^2 + 8000? − 250000 takes x, the number of items produced of a particular new consumer electronic device, and gives P, the profit generated for the manufacturer (in thousands of dollars). Determine the maximum profit.

2. The cost of operating a jet-powered commercial (passenger-
carrying) airplane varies as the three-halves (3/2) power of its
velocity; specifically, Co kny3/2, where n is the trip length in
miles, k is a constant of proportionality, and vis velocity in miles
per hour. It is known that at 400 miles per hour, the average cost of
operation is $300 per mile. The company that owns the aircraft
wants to minimize the cost of operation, but that cost must be
balanced against the cost of the passengers' time (CC), which has
been set at $300,000 per hour. At what velocity should the trip be
planned to minimize the total cost, which is the sum of the cost of
operating the airplane and the cost of passengers' time?
The function P(x) - 1.25x² + 775x - 7000 gives
the profit when x units of a certain product are sold.

b) the average profit per unit when 85 units are sold

c) the rate that profit is changing when exactly 85 units
are sold

d) the rate that profit changes on average when the
number of units sold rises from 85 to 170.

- Michael’s Lobster Food Truck has been operating for three years, but he’s yet to make a profit in the competitive food truck industry. Last year, he sold 2,500 items at an average price of $12.

Let q₁ indicate the amount produced of the first version. The cost function c(q₁) for the first version (expressed in euros) can be described by the equation c(q₁) = 9₁ · √√0.59² +59₁ 10 a) For which value(s) of q₁ is the instantaneous rate of change of the cost function equal to 1.75? You may use the graphical calculator to find zeros of a polynomial function if needed. b) Using the result from a), give a precise economic meaning for the instantaneous rate of change of 1.75. We now denote 92 as the amount produced of the second version. The equation of the cost function c(9₂) for the second version is unknown. We do know that the current cost for a production of 2 units of the second version is 50 monetary units and that the elasticity of the cost in terms of the produced amount when 92 = 2 is equal to 1.88. c) Give a linear approximation ƒ of the cost function c(9₂) for production amounts close to q₂ = 2.arrow_forwardSally Statistics is implementing a system of statistical process control (SPC) charts in her factory in an effort to reduce the overall cost of scrapped product.
