Suppose the moon has a radius of r miles and a payload weighs p pounds at the surface of the moon (at a distance of r miles from the center of the moon). when the payload is x miles from the center of the moon (x ≥ r), the force required to overcome the gravitational attraction between the moon and the payload is given by the following relation: required force = f(x) = r2p x2 pounds for example, the amount of work done raising the payload from the surface of the moon (i. e., x = r) to an altitude of r miles above the surface of the moon (i. e., x = 2r) is work = b f(x) dx a = 2r r2p x2 dx r = rp 2 mile-pounds how much work would be needed to raise the payload from the surface of the moon (i. e., x = r) to the "end of the universe"?

There is a cost associated with each source of financing. discuss the cost of debt, preferred stock, common stock, and retained earnings in detail. which source of financing is typically less expensive? why? why do financial managers try to determine the optimal capital mix? be specific.

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)
