Susan has reached full retirement age (FRA). She is trying to decide between starting Social Security benefits of $2,200 per month now, or delaying receipt for three years and using her savings to provide current income. By delaying three years, her benefit would increase to $2,728 per month. Ignoring the time value of money and cost-of-living adjustments, use the break-even calculation to determine how much longer Susan will need to live in order for delaying to "pay off." A) She should delay beyond FRA regardless of her life expectancy in order to maximize her lifetime benefit. B) She should begin her benefits at FRA regardless of her life expectancy in order to maximize her lifetime benefit. C) She should delay only if she expects to live beyond the next 15½ years or so. D) She should begin at FRA if she expects to live beyond the next three years.

You organize an 8-hour training for 4 hourly, local employees. The training is led by the manager who earns a salary of $ \$ 48,000 $, and by an assistant manager who earns $ \$ 36,000 $. Materials cost is $ \$ 40 / $ person and food is $ \$ 22 $ / person. If the hourly employees make $ \$ 14 $ / hour, what is the cost of this training event? \begin{tabular}{|l|l|} \hline$ \$ 1,170 $ & $ \$ 2,570 $ \\ \hline$ \$ 1,046 $ & $ \$ 1,090 $ \\ \hline \end{tabular}

c. Part C An uncontrolled half-wave rectifier with a freewheeling diode connected across a resistive- inductive load is shown in Figure Q1(c). The load voltage across the resistive-inductive load is given by Equation (1) and the Fourier series representation of the load voltage is given by Equation (2). Determine the average load voltage and current and determine the power absorbed by the resistor. Consider $n < 8$. $V_o = \begin{cases} 200 \sin(\omega t) & \text{; positive half cycle} \\ 0 & \text{; negative half cycle} \end{cases}$ (1) $V_o(t) = \frac{V_m}{\pi} + \frac{V_m}{2} \sin(\omega_o t) - \sum_{n=2,4,6,...}^{\infty} \frac{2V_m}{(n^2 - 1)\pi} \cos(n\omega_o t)$ (2)

Consider the differential system \begin{equation*} \frac{d}{dt} \begin{pmatrix} x \\ y \end{pmatrix} = \begin{pmatrix} 1 & -e^t \\ e^t & 1 \end{pmatrix} \begin{pmatrix} x \\ y \end{pmatrix}. \end{equation*} Show that $\begin{pmatrix} e^t \cos(e^t) \\ e^t \sin(e^t) \end{pmatrix}$ and $\begin{pmatrix} -e^t \sin(e^t) \\ e^t \cos(e^t) \end{pmatrix}$ are solutions to this system. Compute the natural fundamental matrix of this system associated with $t = 0$. Solve the initial-value problem for this system with $x(0) = 1$ and $y(0) = 1$.
