Find a system of differential equations and initial conditions for the currents in the network given in the schematic diagram. Assume that all initial currents are zero. Solve for the currents in each branch of the network. What are the system of equations? $I_3 = \frac{dq}{dt}$ where $q$ is the charge on the capacitor. A. $4 - 4\frac{dl_1}{dt} - 14I_2 = 0$, $I_2 + \frac{dq}{dt} - I_1 = 0$ and $-2\frac{dq}{dt} - 6q + 14I_2 = 0$ B. $4 - 4I_1 - 14\frac{dl_2}{dt} = 0$, $I_2 + \frac{dq}{dt} - I_1 = 0$ and $-2\frac{dq}{dt} - 6q + 14\frac{dl_2}{dt} = 0$ C. $4 + 4I_1 + 14\frac{dl_2}{dt} = 0$, $I_2 + \frac{dq}{dt} + I_1 = 0$ and $2\frac{dq}{dt} + 6q + 14I_2 = 0$ D. $4 + 4\frac{dl_1}{dt} + 14I_2 = 0$, $I_2 + \frac{dq}{dt} + I_1 = 0$ and $2\frac{dq}{dt} + 6q + 14I_2 = 0$ What are the initial conditions? $I_1(0) = I_2(0) = I_3(0) = What are the currents in each branch of the network? $I_1 = I_2 = I_3 = (Type exact answers.)

Calculate each of the limits in Exercises 49-64. Some of these limits are made easier by considering the logarithm of the limit first, and some are not. 49. $\lim_{x \to 0^{+}} x^{\ln x}$ 51. $\lim_{x \to 2^{+}} (x - 2)^{x^{2} - 4}$ 53. $\lim_{x \to 1^{+}} x^{1/(x - 1)}$ 55. $\lim_{x \to \infty} x^{1/x}$ 57. $\lim_{x \to \infty} \left(\frac{1}{x + 1}\right)^{x}$ 59. $\lim_{x \to 1^{+}} (x - 1)^{\ln x}$ 61. $\lim_{x \to 0^{+}} x^{\sin x}$ 63. $\lim_{x \to 0^{+}} (\cos x)^{1/x}$ 50. $\lim_{x \to \infty} x^{\ln x}$ 52. $\lim_{x \to 0^{+}} (x^{2} + 1)^{x}$ 54. $\lim_{x \to 0^{+}} x^{2x}$ 56. $\lim_{x \to \infty} \left(\frac{1}{x}\right)^{x}$ 58. $\lim_{x \to \infty} \left(\frac{x}{x - 1}\right)^{x}$ 60. $\lim_{x \to 1^{+}} (\ln x)^{x - 1}$ 62. $\lim_{x \to 0^{+}} (\sin 3x)^{2x}$ 64. $\lim_{x \to 0} (1 - \cos x)^{x}$

In a study on the relationship between sleep and stress, college students indicated how many hours they slept per day and their stress level on a scale of 1 to 10. The data appear below. SLEEP STRESS 4 7 7 6 8 2 9 5 2 9 6 4 7 5 3 8 1. Sketch a scatter plot of the data. 2. Calculate the correlation coefficient. 3. Based on this finding, describe in words the relationship that the data suggests. Include both direction (i.e., positive or negative) and an interpretation. 4. How much variability in stress scores is accounted for by the number of hours slept per day? 5. What stress score would you predict for a student who sleeps 5 hours per day? 6. What is the amount of error, on average, that you would expect from making such a decision? 7. Does lack of sleep cause stress? What could be one alternate explanation for the findings?
