please provide detailed answer.

CM Corp. has annual cost of debt and common equity of RB=8.0% and RS=18.0%. It is 45,000 corporate bonds outstanding, valued at $987.62 each, and 36,500,000 common ares with a market value of $1.55 each. DCM's corporate tax rate is 35%. DCM Corp. ists in a Modigliani and Miller with corporate taxes. a) What is the cost of capital for DCM Cop. ( 121 marks) b) Draw and label a diagram (label both axes) showing the relationship of the cost of equity for the unlevered firm, the after-tax cost of debt, the cost of equity for the levered firm and the WACC in this M\&M world. (1 1/2 marks) c) Suppose that in the M\&M world describe, DCM Corp. decides to decrease financial leverage to zero, by moving to all-equity financing. Calculate DCM's new cost of capital? (Assume debt is essentially risk-free.) ( 11/2 marks) d) If the value of the firm is determined by the following equation: VL=VU+TcBB2 where PVfinanacialdistresscosts=B2, and B is in millions of dollars, what would the optimal level of debt be (in millions of dollars, to 2 decimal places)? Verify that you have found the optimal level of debt (for full marks). ( 1112 marks) Hint: The first derivative is: The second derivative is: VL=Tc2B VL=2
