$y'' + 3y' + 2y = f(t) : y(0) = 1, y'(0) = -1.$ where, $f(t) = \begin{cases} 20\cos(2t) & \frac{\pi}{4} < t < \frac{3\pi}{4} \\ 0 & Otherwise \end{cases}$ Some useful angle sum formulas for trigonometric functions are as follows: $\cos \left(\theta \pm \frac{\pi}{2}\right) = \mp \sin \theta, \cos \left(\theta \pm \frac{3\pi}{2}\right) = \pm \sin \theta ; \sin \left(\theta \pm \frac{\pi}{2}\right) = \pm \cos \theta, \sin \left(\theta \pm \frac{3\pi}{2}\right) = \mp \cos \theta.$

Stewart's suppliers are fed up and will not continue selling to Stewart unless Stewart begins making prompt payments (that is, paying in 30 days or less). The firm is going to have to reduce its level of accounts payable, either to an amount that is equal to 30 days purchases (if it does not take discounts) or to 10 days purchases (if it decides to take discounts). Management has decided to obtain the needed funds by borrowing on an additional 1-year note payable (call this a current liability) from its bank at a rate of 16%, discount interest, with a 15% compensating balance required. The cash currently held by Stewart is needed for transactions, so it cannot be used as part of the compensating balance. So, the issue now facing the company is this: How much trade credit should it use, and how large a loan should it obtain from its bank? a. How large would the accounts payable balance be if Stewart takes discounts? If it does not take discounts and pays in 30 days? Input Data Discount, if taken 1% Days actually taken to make payment 50 Term of discount (days) 10 Interest rate on bank loan 16% Payment due (days) 30 Required compensating balance 15% Accounting days/year 360 Purchases per day = Old A/P / old days until payment = 2,500,000 / 50 = $ 50,000.00 Accounts payables = Term of discount (days) x Purchases per day = Accounts payables if take discounts = 10 x $ 50,000 = $ 500,000 Accounts payables if don't take discounts = 30 x $ 50,000 = $ 1,500,000

In physics, work is defined as the transfer of energy when a force causes displacement in the direction of the force. For a constant force in one dimensional motion, work can be calculated by multiplying the force component along the path by the distance traveled. How does this concept of work change when dealing with forces in multiple dimensions?

1. (a) The sign test and the Wilcoxon signed-rank test can both be used to test hypotheses about the location of a population. i. When is it more appropriate to use the sign test over the Wilcoxon signed- rank test? Refer to the shape of the population distribution in your an- swer. ii. What (if any) limitations does the sign test have? iii. Let $x_1, x_2,..., x_n$ be a sample taken at random from a population. Describe the steps in computing the Wilcoxon signed-rank test statistic for these data. (15 marks) (b) Ten cows were used in a study to examine methane emissions under two dietary regimes. Five cows were randomly assigned to each regime and the response (CH$_4$ flux in grams per day) was recorded. The dataset is given in the following table. Regime 1 210 220 254 261 280 Regime 2 275 310 330 475 520 A Kolmogorov-Smirnov test was used to compare the two regimes. The test was implemented using R software, with output: Two-sample Kolmogorov-Smirnov test data: r1 and r2 D = 0.8, p-value = 0.07937 alternative hypothesis: two-sided i. State the null and alternative hypothesis. ii. Show how the test statistic was computed. iii. State the conclusion, using $\alpha$ = 0.05. (18 marks)

Glass refractive index determination is commonly used in forensic science to identify a glass sample and match it to a suspected source (e.g., manufacturer, broken window, etc). a) Explain how you would use what information you have learned so far in this class to determine whether glass fragments embedded in a suspect’s shoe match the glass of a broken car window at the crime scene. b) If the two glass samples matched, what refraction angle would you expect with an incident angle of 10 degrees from the normal?
