The differential equation below models the temperature of an 89°C cup of coffee in a 23°C room, where it is known that the coffee cools at a rate of 1°C per minute when its temperature is 73°C. Solve the differential equation to find an expression for the temperature of the coffee at time t. (Let y be the temperature of the cup of coffee in °C, and let t be the time in minutes, with t = 0 corresponding to the time when the temperature was 89°C.)

Which of the following statements is correct? stockholders should generally be happier than bondholders to have managers invest in risky projects with high potential returns as opposed to safe projects with lower expected returns. potential conflicts between stockholders and bondholders are increased if a firm's bonds are convertible into its common stock. takeovers are most likely to be attempted if the target firm’s stock price is above its intrinsic value. one advantage of operating a business as a corporation is that stockholders can deduct their pro rata share of the taxes the firm pays, thereby eliminating the double taxation investors would face in a partnership.
