5 1 point You have a stock solution of the antibiotic streptomycin at a concentration of 5mg/mL. You want to make a 10mL solution of LB broth with a final concentration of 50µg/mL streptomycin. Use the equation $C_1V_1 = C_2V_2$ to solve for the volume of streptomycin stock transferred and the volume of diluent needed. $V_1$ = 0.1mL 5mg/mL streptomycin; diluent = 10.1mL $V_1$ = 0.1mL 50µg/mL streptomycin; diluent = 9.9mL $V_1$ = 0.1mL 50µg/mL streptomycin; diluent = 10.1mL $V_1$ = 0.1mL 5mg/mL streptomycin; diluent = 9.9mL Next

b. (8pts) Consider the ODE problem $x^2y'' + xy' + (-x^2 - 9)y = 0$. Suppose that we can choose between a power series solution centered at $x_0 = 0$ or a solution centered at $x_0 = 3$. Please answer the following questions. i. Which $x_0$ should you choose to obtain the largest radius of convergence? Explain your answer. ii. What method would you use to obtain the general solution centered at $x_0 = 0$? Write the general solution to the ODE (Your solution should be fairly concise!).
