In Exercises 1 3, use the following information: After much discussion, the Konigsberg city council decided that it would be a good thing if the city's residents succeeded in _finding a bridge walk. That is. a walk that would take the walker across each of the city's bridges once. Council members reasoned that a bridge walk would Joseter civic pride and attract tourists. They voted to close one bridge if doing so would allow the creation of a bridge walk. ( Note: The Konigsberg story presented earlier in this section is true. However, the details presented in the exercises are not.
Is there a bridge whose closure would create a bridge walk if the walk's starting point had to be different from its stopping point? If your answer is "yes," specify the bridge, draw a graph of the new six-bridge system, and describe the walk. If your answer is "no," explain why.

- Name the four characteristics of a good definition.arrow_forwardMonroe County is trying to determine where to place the county fire station. The locations of the county’s four major towns are as follows: (10, 20), (60, 20), (40, 30), and (80, 60) (see Figure 7.50). Town 1 averages 40 fires per year; town 2, 25 fires; town 3, 20 fires; and town 4, 30 fires. The county wants to build the fire station in a location that minimizes the average distance that a fire engine must travel to respond to a fire. Because most roads run in either an east-west or a north-south direction, the fire engine must do the same. For example, if the fire station is located at (30, 40) and a fire occurs at town 4, the fire engine has to travel |80 - 30| + |60 - 40| = 70 miles to the fire. a. Determine where the fire station should be located. Round your answers to three decimal places. X Y Location of fire stationarrow_forward4.
