K Monetary policy has so many different channels through which it can operate. This is an advantage because: O A. it can increase uncertainty over the effects of any given policy. B. it lowers short-term nominal interest rates to the zero bound, meaning traditional monetary policy is effective. C. so many channels can cause the central bank to be "responsibly irresponsible." D. if the policy is rendered ineffective through any one particular channel, there are other channels through which the same policy can still impact the economy

9. The electric circuit shown in Figure 7.9.1 is described by the system of differential equations \begin{equation} \frac{dx}{dt} = \begin{pmatrix} -\frac{1}{2} & -\frac{1}{8} \\ 2 & -\frac{1}{2} \end{pmatrix} x + \begin{pmatrix} \frac{1}{2} \\ 0 \end{pmatrix} I(t), \end{equation} (49) where $x_1$ is the current through the inductor, $x_2$ is the voltage drop across the capacitor, and $I(t)$ is the current supplied by the external source. a. Determine a fundamental matrix $\Psi(t)$ for the homogeneous system corresponding to equation (49). Refer to Problem 20 of Section 7.6. b. If $I(t) = e^{-t/2}$, determine the solution of the system (49) that also satisfies the initial conditions $x(0) = 0$. $L = 8$ henrys $I(t)$ $C = \frac{1}{2}$ farad $R = 4$ ohms $R = 4$ ohms

Tutorial Exercise Determine whether the planes $a_1x + b_1y + c_1z = d_1$ and $a_2x + b_2y + c_2z = d_2$ are parallel, perpendicular, or neither. The $a_1a_2 + b_1b_2 + c_1c_2 = 0$. $6x + y - 5z = 4$, $-42x - 7y + 35z = 5$ Step 1 Compare the given equations with the equations $a_1x + b_1y + c_1z = d_1$ and $a_2x + b_2y + c_2z = d_2$ then $a_1 = 6$, $b_1 = 1$, $c_1 = -5$, $a_2 = -42$, $b_2 = -7$, and $c_2 = 35$ Step 2 Observe the following. $a_2 = -42$ $= (-7)($oxed{6})$ $= oxed{ }$ $a_1$
