Determining Cost Estimating Function
A product plant is being considered for a new booming market. Total fixed cost for design, land, and plant construction is $105. The variable cost of producing product is a function C (n) = 100n - 3 x 10-3 n2 + 10-7 n3 where n = number of product produced.
(a) Determine the total cost function C (T). (Hint: It includes the cost of producing the product and fixed cost.)
(b) Find the marginal cost function Cm for producing the product.
(c) Find the number of product for minimum marginal cost. What is the marginal cost at this point? What is the average cost per unit at this level of production?
(d) Total revenue is given by S (n) = 250 n. Find the marginal price. Determine the functions for total profit, and marginal profit.
(e) Find the point to maximize profit.
(f) Graph these cost equations.
What is meant by the value of f, a, s on the fresh concrete mix is:A. The weight ratio of water to the weight of the cement mixture. B. The weight ratio of water to the weight of cement and aggregates. C. Factors dough with a water content ratio of t..
A sample of dry sand with a specific gravity total of 16.49 kN/m3 and a relative density of 2.67 grains, is placed outdoors. During a rainy period, the sample volume remains constant but the degree of saturation increases to 40%.
A 35 feet diameter oil storage tank is built on a 100 ft thick soil layer. The tank exerts an uniform pressure of 1000 pcf on the ground surface. The groundwater table is 10 ft below the ground surface.
The given groundwater shows the following chemical composition: Sodium =7 mgIL, Calcium = 70 mg/L, Magnesium = 35 mg/L, Potassium = 1 mgIL Bicarbonate = 200 mg/L, Sulfate = 30 mgIL, pH = 7.5 Atomic mass unit: sodium (23), calcium (40), magnesium (24...
