Chapter 7.6, Problem 31E
The graphing calculator screen displays an exponential function that models the U.S. population age 65 and over, y, in millions, x years after 1899. Use this information to solve Exercises 31-32.
a. Explain why an exponential function was used to model the population data.
b. Use the graphing calculator screen to express the model in function notation, with numbers rounded to three decimal places.
c. According to the model in part (b), how many Americans age 65 and over were there in 2010? Use a calculator with a
key or a
d. According to the model in part (b), how many Americans age 65 and over will there be in 2020? Round to one decimal place. Does this rounded number overestimate or underestimate the 2020 population projection displayed by the bar graph? By how much?

The following is known. The complete graph K2t on an even number of vertices has a 1-
factorization (equivalently, its edges can be colored with 2t - 1 colors so that the edges incident
to each vertex are distinct). This implies that the complete graph K2t+1 on an odd number of
vertices has a factorization into copies of tK2 + K₁ (a matching plus an isolated vertex).
A group of 10 people wants to set up a 45 week tennis schedule playing doubles, each week, the
players will form 5 pairs. One of the pairs will not play, the other 4 pairs will each play one
doubles match, two of the pairs playing each other and the other two pairs playing each other.
Set up a schedule with the following constraints: Each pair of players is a doubles team exactly 4
times; during those 4 matches they see each other player exactly once; no two doubles teams play
each other more than once.
(a) Find a schedule. Hint - think about breaking the 45 weeks into 9 blocks of 5 weeks. Use
factorizations of complete…
. The two person game of slither is played on a graph. Players 1 and 2 take turns, building a path in the graph. To start, Player 1 picks a vertex. Player 2 then picks an edge incident to the vertex. Then, starting with Player 1, players alternate turns, picking a vertex not already selected that is adjacent to one of the ends of the path created so far. The first player who cannot select a vertex loses. (This happens when all neighbors of the end vertices of the path are on the path.) Prove that Player 2 has a winning strategy if the graph has a perfect matching and Player 1 has a winning strategy if the graph does not have a perfect matching. In each case describe a strategy for the winning player that guarantees that they will always be able to select a vertex. The strategy will be based on using a maximum matching to decide the next choice, and will, for one of the cases involve using the fact that maximality means no augmenting paths. Warning, the game slither is often described…
Let D be a directed graph, with loops allowed, for which the indegree at each vertex is at most k and the outdegree at each vertex is at most k. Prove that the arcs of D can be colored so that the arcs entering each vertex must have distinct colors and the arcs leaving each vertex have distinct colors. An arc entering a vertex may have the same color as an arc leaving it. It is probably easiest to make use of a known result about edge coloring. Think about splitting each vertex into an ‘in’ and ‘out’ part and consider what type of graph you get.

- Burger Dome sells hamburgers, cheeseburgers, french fries, soft drinks, and milk shakes, as well as a limited number of specialty items and dessert selections. Although Burger Dome would like to serve each customer immediately, at times more customers arrive than can be handled by the Burger Dome food service staff. Thus, customers wait in line to place and receive their orders. Burger Dome analyzed data on customer arrivals and concluded that the arrival rate is 30 customers per hour. Burger Dome also studied the order-filling process and found that a single employee can process an average of 44 customer orders per hour. Burger Dome is concerned that the methods currently used to serve customers are resulting in excessive waiting times and a possible loss of sales. Management wants to conduct a waiting line study to help determine the best approach to reduce waiting times and improve service. Suppose Burger Dome establishes two servers but arranges the restaurant layout so that an…arrow_forwardPEER REPLY 1: Choose a classmate's Main Post. 1. Indicate a range of values for the independent variable (x) that is reasonable based on the data provided. 2. Explain what the predicted range of dependent values should be based on the range of independent values.arrow_forwardNote: A waiting line model solver computer package is needed to answer these questions. The Kolkmeyer Manufacturing Company uses a group of six identical machines, each of which operates an average of 18 hours between breakdowns. With randomly occurring breakdowns, the Poisson probability distribution is used to describe the machine breakdown arrival process. One person from the maintenance department provides the single-server repair service for the six machines. Management is now considering adding two machines to its manufacturing operation. This addition will bring the number of machines to eight. The president of Kolkmeyer asked for a study of the need to add a second employee to the repair operation. The service rate for each individual assigned to the repair operation is 0.50 machines per hour. (a) Compute the operating characteristics if the company retains the single-employee repair operation. (Round your answers to four decimal places. Report time in hours.) La = L = Wa = W =…arrow_forward
