Coronado Industries signed a three-month, zero-interest-bearing note on November 1, 2020 for the purchase of $505700 of inventory. The face value of the note was $516500. Coronado used a "Discount of Note Payable" account to initially record the note. Assuming that the discount will be amortized equally over the 3-month period and that there was no adjusting entry made for November, the adjusting entry made at December 31, 2020 will include a \text{O}credit to Interest Expense for $7200. \text{O}debit to Interest Expense for $7200. \text{O}credit to Discount on Note Payable for $3600. \text{O}debit to Discount on Note Payable for $3600.

In country A, all wage contracts are indexed to inflation. That is, each month wages are adjusted to reflect increases in the cost of living as reflected in changes in the price level. In country B, there are no cost-of-living adjustments to wages, but the workforce is completely unionized. Unions negotiate 3-year contracts. Expansionary monetary policy is likely to have a greater effect in country B In country A, an expansionary monetary policy will raise prices without increasing output because A. input prices lag behind output prices; therefore the AS curve will be vertical. Whereas in country B, production costs adjust automatically to price increases so a rightward shift in the AD curve will increase output because the AS curve will not be vertical. B. production costs adjust automatically to price increases; therefore the AS curve will not be vertical.

4. Let $v = (0, 1, 1)$ and $U = \{u \in \mathbb{R}^3 \mid \text{proj}_v u = 0\}$ a) Show that if $u = (x, y, z) \in \mathbb{R}^3$, then $\text{proj}_v u = \frac{y + z}{2}(0, 1, 1)$ b) Find a Cartesian equation for $U$, i.e., find $a, b, c, d \in \mathbb{R}$ such that $U = \{(x, y, z) \in \mathbb{R}^3 \mid ax + by + cz = d\}$, Give a complete geometric description of $U$. c) Is $U$ a subspace of $\mathbb{R}^3$? d) Find a spanning set for $U$.

7. Home lighting - wiring multiple switches. [10 pts.] A simple circuit for wiring room lighting in a home requires a standard, single-pole double-throw (SPDT) switch, as shown in Fig. 1. The switch is wired such that in the up position the light is ON and in the down position the light is OFF. 120 V AC Figure 1: Single-pole double-throw (SPDT) switch and light bulb circuit. (a) This circuit works quite well if only one switch is required to turn on the light. What if the room has two entrances and requires two switches to turn on the light? This circuit is referred to as an Electrician's "three-way" switch. Show how this can be accomplished by drawing a circuit diagram similar to the above figure, using just two of the SPDT switches. (b) In order to generalize the lighting problem to more than two switches, we need to introduce another switch: the double-pole double-throw (DPDT) switch, as shown in Fig. 2. This is basically two SPDT switches linked in parallel and constrained to move together. First, show how to wire the DPDT switch to cross a pair of wires. That is, a pair of wires comes in, a pair of wires comes out, and the signal is crossed if the switch is up and remains unchanged if the switch is down. Figure 2: Double-pole double-throw (DPDT) switch. (c) Now use the above information and what you know from the Electrician's three way switch worked out already to draw the circuit diagram for three switches. You will need two SPDT and one DPDT switch to accomplish this. (d) Having solved the problem for N = 2 and N = 3 switches, state and sketch how to generalize the problem for N light switches. Explicitly indicate how many each of the SPDT and DPDT switches are required.
