Question

With respect to engineering economics and the internal rate of return (IRR), Descartes’ rule of signs indicates there will be at most as many _____ rates of return as there are sign changes in the cash flow profile.

Answer 1

Answer:

''there will be at most as many POSITIVE rates...''

Explanation:

The measure of investments' rate of return which excludes external factors such as inflation is known as Internal Rate of Return(IRR)

It is used in;

(1). Savings and loans.

(2). Liabilities

(3). Fixed incomes

(4). Private equity and capital management.

(5). Maximizing total present value and so on.

It can be calculate using the formula below:

NPV= C(n)/(1+r)^n = 0

That is internal rate of return can be use in solving NPV = 0.

Therefore, 'With respect to engineering economics and the internal rate of return (IRR), Descartes’ rule of signs indicates there will be at most as many POSITIVE rates of return as there are sign changes in the cash flow profile.''
