Brigham Tea, Inc., is a processor of low acid tea. The company is contemplating purchasing equipment for an additional processing line. The additional processing line would increase revenues by $90,000 per year. Incremental cash operating expense would be $40,000 per year. The equipment would cost $180,000 and have a nine-year life. No salvage value is projected.

Now, what if, instead, you sold the house for less than you paid for it—say, for $187,500? The same equation can be used to calculate your loss, or the negative rate of return, on the transaction.

Say that you buy a house for $250,000 (for simplicity let's assume you pay 100% cash). Six years later, you decide to sell the house maybe your family is growing and you need to move into a larger place. You are able to sell the house for $335,000, after deducting any realtor's fees and taxes. Find simple rate of return on the purchase and sale of the house.

‘Customers who bought this also bought this…’ we often see this when we shop on Amazon. What is the logic behind recommendation engines?

Sketch and label each of the following three signals: 

i) y(t)= u(t+3)+u(t-3) ii) y(t)= e^-tu(t) iii) y[n]=δ[n]-δ[n-3]

Jamylla and Janylla are on a hike. Both hikers begin a trip by walking, the first leg A: 2.65 km, 140° from their base camp, on their second leg B: 4.77 km, 252° and to complete their final leg C: 3.18 km, 332°. What is the magnitude and direction of their final position from their base camp? Apply polygon method and component method and compare their

results.
