When determining if three given lengths could represent the sides of a right triangle, how do you choose which side length to put on the side of the
Pythagorean Theorem that has only one variable?

Luther Industries has no debt and expects to generate free cash flows of $48 million each year. Luther believes that if it permanently increases its level of debt to $100 million, the risk of financial distress may cause it to lose some customers and receive less favorable terms from its suppliers. As a result, Luther's expected free cash flows with debt will be only $44 million per year. Suppose Luther's tax rate is 40%, the risk-free rate is 6%, the expected return of the market is 14%, and the beta of Luther's free cash flows is 1.25 (with or without leverage). The value of Luther with leverage is closest to:.

A) 11.5%.

B) 10.8%.

C) 9.8%.

D) 13.0%.The average cost c (in dollars) to manufacture x T-shirts is given by the function c=5x+410/x. Express the number of T-shirts in terms of the average cost.
