The present value of a stream of cash flows you expect to received will always increase when: a. the interest rate is greater than zero and the number of compounding periods decrease. b. the interest rate is zero and the number of compounding periods decrease. c. the interest rate is zero and the number of compounding periods increase. d. the interest rate is greater than zero and the number of compounding periods increase.

The larger the investment you make, the easier it will be to: get money from other sources. guarantee cash flow. buy insurance. streamline your products.

Suppose life expectancy in years (l) is a function of two inputs, health expenditures (h) and nutrition expenditures (n) in hundreds of dollars per year. the production function is upper l equals ch superscript 0.40 baseline upper n superscript 0.60l=ch0.40n0.60. beginning with c = 1, a health input of $400400 per year (hequals=44) and a nutrition input of $400400 per year (nequals=44), show that the marginal product of health expenditures and the marginal product of nutrition expenditures are both decreasing. the marginal product of health expenditures when h goes from 44 to 55 is nothing, and the marginal product of health when h goes from 66 to 77 is nothing. (round your answers to three decimal places.)

Industrial engineers who specialize in ergonomics are concerned with designing workspace and devices operated by workers so as to achieve high productivity and comfort. a paper published in this research area reports on a study of preferred height for an experimental keyboard with large forearm-wrist support. a sample of 31 trained typists resulted in an average preferred height of 80.0 cm
