Step 5 We have found the following complementary function for the given differential equation. $y_c = c_1e^{-x/2} + c_2e^{x/2}$ We have also found that for $y_1 = e^{-x/2}$, $y_2 = e^{x/2}$, $u_1 = -\frac{xe^{x/2}}{4} + \frac{e^x}{4}$ and $u_2 = \frac{x^2}{8}$, a particular solution for the equation is given by $y_p = u_1y_1 + u_2y_2$. Use the fact that $y = y_c + y_p$ is the general solution of the nonhomogeneous differential equation to solve. y(x) = $c_1e^{-x/2} + c_3e^{x/2} + (\frac{1}{8})x^2e^{x/2} + (-\frac{1}{4})xe^{x/2} + \frac{e^{x/2}}{4}$ Step 6 We have found the general solution as follows and are given initial conditions. Note that like terms have been combined and $c_2$ replaced by $c_3$. y(x) = $c_1e^{-x/2} + c_3e^{x/2} + \frac{x^2e^{x/2}}{8} - \frac{xe^{x/2}}{4}$ To find particular solution, we first need the derivative of y(x). y'(x) = $(?)c_1e^{-x/2} + (?)c_3e^{x/2} + (?)x^2e^{x/2} + (?)xe^{x/2} + (?)e^{x/2}$

b) BuzzMart Inc. issued a 30-year, 7% coupon interest rate, $1 000 par value bond that pays interest semi-annually. The required return is currently 6%. Compute the value of the bond. c) Tsuz Industries has paid a dividend of $3.50 per share for the past year (DO = $3.50). The Chief Finance Officer expects the dividend to grow at a rate of 5% per annum for the foreseeable future. Assume investors require a rate of return of 12%. (i) Calculate the current price of the stock. (ii) If the stock currently trades at $53, would you buy it? d) Rainbow Airways is in the 40% tax bracket. Information on the company's debt, preferred stock and common stock are as follows: Debt The company can issue bonds at a yield to maturity of 8.25%. Preferred Stock The company can sell 9% preferred stock at its $55 per share par-value. Floatation costs are $5 per share. Common Stock Price per share is currently $50. Dividends are projected at $4 per share next year with a dividend growth rate of 5%. There are no floatation costs. (i) Calculate the cost of debt. (ii) Calculate the cost of preferred stock. (iii) Calculate the cost of common stock. (iv) Rainbow Airways' capital structure is 20% debt, 40% preferred stock and 40% common stock. Calculate the weighted average cost of capital (WACC).
