13. Consider the linear DE $xy' = \frac{x^2 + xy}{x + y}$. Which value of a and b, the given DE will be homogenous? I. $a = 0$ and $b = 1$ II. $a = 1$ and $b = 0$ III. $a = 1$ and $b = 2$ IV. $a = 2$ and $b = 1$ 14. The roots of the characteristic equation of the third order homogenous DE is $r_1 = 0, r_2 = 1, r_3 = 1$. The general solution of the given DE is I. $y = c_1e^x + c_2e^x + c_3$ II. $y = c_1e^x + c_2xe^x + c_3$ III. $y = c_1e^x + c_2x^2e^x + c_3x$ IV. $y = c_1e^x + c_2e^x + c_3x$ V. 15. According to the drag equation the velocity of an object moving through a fluid can be modeled by the equation $y' = -ky$ where k is constant. An object moving through the water has an initial velocity of 40 m/s. One seconds later, the velocity has 30 m/s. What will the velocity in m/s be nineth seconds? a. 25 II. 20 III. 15 IV. 10 V. 5
