Review Question 4:
I agree with all the characteristics of professionalism that are described in this book. Professionals adhere to a code of ethics; these include responsibilities to the public, employers, customers, and colleagues. Professionals create organizations to help them share (peer-to-peer) training, values, and skills. Though there are similarities between trade workers and professionals, each seeking to further their education in their chosen fields. Professionals are more involved in the education of their fields by creating organizations. These organizations work with colleges to help standardize and provide education that meets a career’s changing needs, employ competent faculty, and introduce new technologies. It also promotes and authenticates the profession. Chapter Test Questions pg.17&18 1-8:

A farmer wishes to transport a truckload of eggs from city 1 to city 2 through a road network as above. The truck will incur a certain amount of breakage on each road segment, where the % value shown on the network is the percentage of eggs broken if the truck passes the road arc. How should the truck be routed to minimize the total breakage?
(1) Formulate the problem as a shortest path problem (showing the resulted shortest path problem such as drawing the network and specifying arc costs).
(2) Solve the problem by Dijkstra’s algorithm.
************************************************************************
Optional Questions (no submission required)
Suppose that a shortest path from node 1 to node 2 has been found. Let the cost be C.
(1) If, for all arcs in the network, the cost is increased by k times, k>0, will the shortest path change?
(2) If, for all arcs in the network, the cost is increased by a constant k, k>0, will the shortest path change?
(3) If, for all arcs starting from node 1, the cost is increased by a constant k, k>0, will the shortest path change?
(4) If, for one arc on the shortest path, the cost is increased by a constant k, k>0, will the new shortest path cost be C+k?
(5) If, for one arc on the shortest path, the cost is decreased by a constant k, k>0, will the new shortest path cost be C-k?
Ans(1):
First convert the % lost into efficiency as below:
Then define the cost of each arc as...

Homework 1
The task at hand is to design a program, using pseudocode, which will calculate the square feet of a house with no more than four rooms. It must be additionally assumed that each of these rooms is rectangular. The required output is the accurate calculation of the aggregate square footage of these rooms. The required input to arrive at this output is the length and width of each of the rooms, the multiplication of each individual room length and width, and the sum of the combined multiplication results. The required output will be obtained through proper declaration of each variable, which consists of multiple floating point values. For my analysis the length of a room will be represented as L plus a number to identify the room, such as L1. The width will similarly be represented as W1, and the area, or length times width, as A1. The resulting output, or sum of all A values, will be calculated. The following is a list of the required input and resulting output.
RoomName as String
L1 as Float
L2 as Float
L3 as Float
L4 as Float
W1 as Float
W2 as Float
W3 as Float
W4 as Float
A1=L1*W1
A2=L2*W2
A3=L3*W3
A4=L4*W4
TotalSqFt=A1+A2+A3+A4
Using this design, The following pseudocode has been produced:

Question 1
You are head of a Family Endowment for the Arts. You have decided to fund a music school in
San Diego in perpetuity. You will give the school $1 million immediately, and subsequent
annual $1 million dollar payments growing at the rate of inflation, which you estimate to be 3%
per year (i.e., you will contribute $1,000,000 plus inflation next year (one year from today), the
year after, the year after, etc.,). If the interest rate is 8% per year, what is the present value of
your gift?
Question 2
Your friend has a business she wants you to value. The business will not generate any money
for the next three years, but in the fourth year it will start turning a profit and will make a
payment (the first payment) of $150,000 to the owners at the end of the fourth year. Your
friend expects to be able to grow the business, and the payments made to the owners, by 4%
per year forever, and the owners will receive their payments at year end. If the appropriate
discount rate is 14%, what is the value of the business today?
