Frontier Airlines hedged the cost of jet fuel by purchasing options that allowed the airline to buy fuel at a fixed price for 2 years. The savings in fuel costs were $140,000 in month 1,$141,400 in month 2, and amounts increasing by 1% per month through the 2-year option period. What was the present worth of the savings at an interest rate of 18% per year, compounded monthly?

A torpedo 8 m below the surface in 20°C seawater cavitates at a speed of 21 m/s when atmospheric pressure is 101 kPa. If Reynolds number and Froude number effects are negligible, at what speed will it cavitate when running at a depth of 20 m? At what depth should it be to avoid cavitation at 30 m/s?

Suppose the following facts are given about the signal x(t) with Laplace transform X(s): 1. x(t) is real and even. 2. X(s) has four poles and no zeroes in the finite s-plane. 3. X(s) has a pole at $$ s=(1/2)e^jπ/4. 4. ∫_{-∞}^∞ x(t)dt=4. $$ Determine X(s) and its ROC.

The saturation concentration of dissolved oxygen in freshwater can be calculated with the equation $$ Ino_{sf} = - 139.34411 + \frac{1.575701\times 10^5}{T_a} - \frac{6.642308\times10^7}{T^2_a}+\frac{1.243800\times10^{10}}{T^3_a} - \frac{8.621949\times10^{11}}{T^4_a} $$ where $$ o_{sf} $$ = the saturation concentration of dissolved oxygen in freshwater at 1 atm (mg/L) and $$ T_a $$ = absolute temperature (K). Remember that $$ T_a = T + 273.15, $$ where T = temperature (°C). According to this equation, saturation decreases with increasing temperature. For typical natural waters in temperate climates, the equation can be used to determine that oxygen concentration ranges from 14.621 mg/L at 0°C to 6.413 mg/L at 40°C. Given a value of oxygen concentration, this formula and the bisection method can be used to solve for temperature in °C. (a). If the initial guesses are set as 0 and 40°C, how many bisection iterations would be required to determine temperature to an absolute error of 0.05°C? (b). Develop and test a bisection program to determine T as a function of a given oxygen concentration to a prespecified absolute error as in (a). Given initial guesses of 0 and 40°C, test your program for an absolute error = 0.05°C and the following cases: $$ o_{sf} = 8,10, and 12 mg/L. $$ Check your results.
