Q: If the amount of capital that a company has at time t
If the amount of capital that a company has at time t is f (t), then the derivative, f'(t), is called the net investment flow. Suppose that the net investment flow is √t million dollars per year (wher...
See AnswerQ: If revenue flows into a company at a rate of f (
If revenue flows into a company at a rate of f (t) 9000 √1 + 2t, where is measured in years and f (t) is measured in dollars per year, find the total revenue obtained in the first four years.
See AnswerQ: High blood pressure results from constriction of the arteries. To maintain
High blood pressure results from constriction of the arteries. To maintain a normal flow rate (flux), the heart has to pump harder, thus increasing the blood pressure. Use Poiseuille’...

If n is a positive integer, prove that f10 (ln x) n dx = (-1) n n!
See AnswerQ: The dye dilution method is used to measure cardiac output with 6
The dye dilution method is used to measure cardiac output with 6 mg of dye. The dye concentrations, in mg/L, are modeled by c (t) = 20t2-0.6t, 0 < t < 10, where is measured in seconds. Find the cardia...
See AnswerQ: After an 8-mg injection of dye, the readings of
After an 8-mg injection of dye, the readings of dye concentration, in mg/L, at two-second intervals are as shown in the table. Use Simpson’s Rule to estimate the cardiac output.
See AnswerQ: The marginal revenue from the sale of units of a product is
The marginal revenue from the sale of units of a product is 12 – 0.0004x. If the revenue from the sale of the first 1000 units is $12,400, find the revenue from the sale of the first 5000 units.
See AnswerQ: The marginal cost of producing units of a certain product is 74
The marginal cost of producing units of a certain product is 74 + 1.1x – 0.002x2 + 0.00004x3 (in dollars per unit). Find the increase in cost if the production level is raised from 1200 units to 1600...
See AnswerQ: The demand function for a certain commodity is p = 20 –
The demand function for a certain commodity is p = 20 – 0.05x. Find the consumer surplus when the sales level is 300. Illustrate by drawing the demand curve and identifying the consumer surplus as an...
