*2.40 Figure P2.40 shows a circuit for a digital-to-analog DAC). The circuit accepts a 4-bit input binary word here $a_0, a_1, a_2$, and $a_3$ take the values of 0 or 1, and it provides an analog output voltage $v_0$ proportional to the value of the digital input. Each of the bits of the input word controls the correspondingly numbered switch. For instance, if $a_2$ is 0 then switch $S_2$ connects the 20-k$\Omega$ resistor to ground, while if $a_2$ is 1 then $S_2$ connects the 20-k$\Omega$ resistor to the +5-V power supply. Show that $v_0$ is given by \begin{equation*} v_0 = -\frac{R_f}{16}[2^0a_0 + 2^1a_1 + 2^2a_2 + 2^3a_3] \end{equation*} where $R_f$ is in kilohms. Find the value of $R_f$ so that $v_0$ ranges from 0 to -12 volts.

5a. Let $G = (V, E, c)$ be a positively-weighted graph, and recall the \"matrix-multiplication\" algorithm for finding all-pairs distances in a graph. Suppose the optimal path from vertex $i$ to vertex $j$ has a length equal to $k$. Use the definition of \"multiplication\" to prove that $D_{ij}^{k+1} = (D^k \times D^1)_{ij} = D_{ij}^k$
