Concept explainers
Exercises 61–66 use the mathematical system described next.
Many ceiling fans have a four-way switch on a pull chain, with positions off, high speed, medium speed, and low speed. We can build a mathematical system to describe the positions using 0 for off, 1 for high speed, 2 for medium speed, and 3 for low speed. For example, if the fan is off and you pull the chain once, it goes to high speed, so if we use + to represent the operation of combining positions by pulling the chain, 0 + 1 = 1. If it’s on medium speed and you pull the chain three times the result is also high speed (medium → low → off → high), so 2 + 3 = 1.
61. Fill in the operational table we’ve started below for the mathematical system described by the ceiling fan pull chain.

Afterwards it maintains the speed. Also, when t = 0, car B located 6000 ft down the road is traveling towards A at a constant speed of 80 ft/s. Determine the distance traveled by Car A when they pass each other.Write the solution using pen and draw the graph if needed.arrow_forward
