(eks-ten'sÅr, -sÅr), [TA] 1  A muscle the contraction of which causes movement at a joint with the consequence that the limb or body assumes a more straight line, or so that the distance between the parts proximal and distal to the joint is increased or extended; the antagonist of a flexor. See: muscle.
All other things being equal, using internal rate of return (IRR) and net present value (NPV) measurements to evaluate projects often results in the same findings. However, there are a number of projects for which using IRR is not as effective as using NPV to discount cash flows.
Next youll access and clear the cash flow worksheet, enter the data, compute the IRR, and compute the NPV using an interest rate per period ( I ) of 20%. When the word Compute appears in the display, it means the only function you can perform is to compute the value of IRR. The * indicates a computed answer.
