For the graph below, use the nearest neighbor algorithm to find an approximate minimum Hamilton circuit and its weight, starting at the indicated vertex.
Starting at A
A. A ? E ? B ? C ? D ? A; weight = 28 B. A ? C ? E ? B ? D ? A; weight = 29 C. A ? B ? C ? D ? E ? A; weight = 25 D. A ? D ? B ? C ? E ? A; weight = 27
Solve the problem.The average waiting time in a line before getting served is given by ?W = 
where A is the average rate that people arrive at the line and S is the average service time. At a certain bank, the average service time is 4 minutes. By sketching a graph of the equation on the interval 
answer the following questions. What happens to W when A is close to zero? Why does this make sense? What feature of your graph gives this information?
