Question A curve with polar equation $r = \frac{5}{9 \sin \theta + 7 \cos \theta}$ represents a line. Find the Cartesian equation of the line in the form $y = mx + b$. Select the correct answer below: $y = -\frac{5}{9}x + \frac{7}{9}$ $y = -\frac{7}{9}x + \frac{5}{9}$ $y = \frac{5}{9}x - \frac{7}{9}$ $y = \frac{7}{9}x - \frac{5}{9}$ $y = \frac{5}{7}x - \frac{9}{7}$ $y = -\frac{5}{7}x + \frac{9}{7}$

Find $I_o$ in the given circuit, where $I = 28 \angle 40^\circ$ A. Switch the dot on the winding on the right and calculate $I_o$ again. Please report your answer so the magnitude is positive and all angles are in the range of negative 180 degrees to positive 180 degrees. $k = 0.601$ The value of $I_o = -9.90 \angle -67.96^\circ$ A. After switching the dot on the winding on the right, the value of $I_o = -9.10 \angle$ A.

Suppose R is the region bounded from above by the graph of $f(x) = 12x - x^2$ and from below by the graph of $g(x) = x$ over the interval $[3, 7]$. Find the center of mass of the region. Assume that the region has a constant density $\delta$. $(\bar{x}, \bar{y}) = $ Note: your answer should be an ordered pair and you may use decimals in this problem. If you give a rounded answer, use at least 3 decimal places.
