Because of friction, rotational kinetic energy is not conserved while the disks' surfaces slip over each other. What is the final rotational kinetic energy, KfKfK_f, of the two spinning disks? Express the final kinetic energy in terms of ItItI_t, IrIrI_r, and the initial kinetic energy KiKiK_i of the two-disk system. No angular velocities should appear in your answer.

The next dividend payment by savitz, inc., will be $2.08 per share. the dividends are anticipated to maintain a growth rate of 6 percent forever. if the stock currently sells for $42 per share, what is the required return?

Annuity payments are assumed to come at the end of each payment period (termed an ordinary annuity). however, an exception occurs when the annuity payments come at the beginning of each period (termed an annuity due). what is the future value of a 13-year annuity of $2,800 per period where payments come at the beginning of each period? the interest rate is 9 percent. use appendix c for an approximate answer, but calculate your final answer using the formula and financial calculator methods. to find the future value of an annuity due when using the appendix tables, add 1 to n and subtract 1 from the tabular value. for example, to find the future value of a $100 payment at the beginning of each period for five periods at 10 percent, go to appendix c for n = 6 and i = 10 percent. look up the value of 7.716 and subtract 1 from it for an answer of 6.716 or $671.60 ($100 × 6.716)

Carlton industries is considering a new project that they plan to price at $74.00 per unit. the variable costs are estimated at $39.22 per unit and total fixed costs are estimated at $12,085. the initial investment required is $8,000 and the project has an estimated life of 4 years. the firm requires a return of 8 percent. ignore the effect of taxes. what is the degree of operating leverage at the financial break-even level of output?
