9b 1. Recall circuit IX from the tutorial, which is reproduced at right. In the tutorial, batteries A and B were identical. In this problem, you will consider two cases in which they are not. a. Suppose that the absolute value of the potential difference across battery A were reduced, but battery B is unchanged. When the switch is closed, would bulb 9b light? Explain your reasoning. A 9a B Circuit IX If...
State the linear programming problem in mathematical terms, identifying the objective function and the constraints A firm makes products A and B. Product A takes 3 hours each on machine L and machine M; product B takes 4 hours on L and 3 hours on M. Machine L can be used for 12 hours and M for 10 hours. Profit on product A is $7 and $9 on B. Maximize profit. Maximize 7A 9B Subject to: 3A +4B s 12...
DBF borrows $9B by issuing 2-year bonds. ECB's cost of debt is 12%, so it will need to pay interest each year for the next 2 years, and then repay the principal $9B in year 2. ECB's marginal tax rate will remain 35% throughout this period. By how much does the interest tax shield increase the value of DBF?
