Problem definition: Calculate the total value of a group of coins. Assume that the coins are the standard American coins: penny, nickel, dime, quarter.

A.Problem Analysis – Following the directions in the assignment, clearly write up your problem analysis in this section. a)What is the required output?
oTotal value of a group of joins
oName of the coins
oValue of the coins
b)What is the necessary input?
oIn order to output the item’s Value, the program must know the value of the coin. (Dime = 10 cents, Quarter = 25 cents, etc…) oThe program must also know what coins I am grouping together oIn order for the program to calculate the total value of a group of coins, it must know the Value of each coin itself and it must know the group of joins I choose. After choosing the coins, it should calculate the total based on Value and Name of the coin c)How you will obtain the required output from the given input? oTo compute the “GroupValue” (total value of a group of coins) we need to know the “CoinValue”(the individual value, in cents, of the coin itself) and the “CoinName” (to separate each coin with its CoinValue, we need to know the name of each coin). It will also need to know the “AmountOfEach” in order to know how many times it should calculate each “CoinValue”. oAn example of the process of finding the total value of a group of coins would be: Say you input 2 Dimes, 1 Penny and 3 Nickels. The program will process the value of the dime, penny and nickel. As it finds the value of each coin, it will process the input of how many times the coin was requested. 2(0.10)+1(.0.01)+3(0.05) = 0.36

Problem definition: Calculate the monthly payment on a loan given the loan amount, the annual interest rate, and the total number of monthly payments.
A. Problem Analysis – Here are the input data, output data and processing step to convert input data into output data.1. Input Data: a. Loan Amount (P) b. Annual percentage rate of interest (r) c. Number of monthly payments (N). 2. Output data: Monthly Payment (M) 3. Processing: The output M can be obtained from the input data by using the following formula: M = P * R* (1+R)^N/((1+R) ^N-1) where R =r/1200 B.

...Understand own ability to fulfil key responsibilities of the leadership role
Leadership is the ability to pinpoint values or objectives which can be reached through encouragement and a cohesive effort through the gradual assistance to the members of the team. The objective can be reached through persistence and insistence in such a way that members are not irritated or discouraged. In a particular company the commercial Department has four branches the Sales team, Business Sales, Customer Experience and Marketing Teams. We will evaluate leadership roles incorporating different Leadership Styles and how they impact the Customer Experience Team and the Sales Team.
The Customer Experience team evaluates the importance of understanding the client, empathising and providing solutions for their queries in a convenient time frame. The clients’ degree of satisfaction dictates the choice of decisions. The democratic approach shows and indicates that once the team members feel important because they are involved they do willingly provide a better service and once they come across some problem or some difficulty they are more prone to discuss it with their supervisor and in so doing they achieve client satisfaction in a quicker manner (Kurt Lewin, 1939). However when there is the autocratic approach which means the Leader has technically his own way, the other team members feel uneasy to approach him and because of this attitude the clients may suffer with the result that they...

1 Define modulation?
The process of putting information onto a high frequency carrier for transmission.
2 What is carrier frequency?
Carrier frequency is used to designate the nominal frequency of a carrier wave and the center frequency of a frequency modulation signal.
3 Name two reasons modulation is used in communications?
The human voice ranges from 20 Hz to 3000 Hz, if these were transmitted directly as radio waves, the signal would be useless. Because of interference from each signal. Low frequency signals are hard to transmit. It would require many miles of antennas to transmit.
4 List parameters of a high frequency carrier varied by low frequency intelligence signal?
Peak value
Angular velocity
Phase angle
5 What are the frequency ranges of MF, HF, VHF, UHF, and SHF?
Medium Frequency (MF) 300kHz-3MHz
High Frequency (HF) 3MHz-30MHz
Very High Frequency (VHF) 30MHz-300MHz
Ultra High Frequency (UHF) 300MHz-3GHz
Super High Frequency (SHF) 3GHz-30GHz

Problem definition: Calculate the usable area in square feet of house. Assume that the house has a maximum of four rooms, and that each room is rectangular.
A. Problem Analysis – Following the directions in the assignment, clearly write up your problem analysis in this section.
This program will compute the area of a house that has four rectangular rooms. Output is the value of the total area (total_area) of the house and is to be calculated by area/length/width input (A1, A2, A3, A4, L1, L2, L3, L4, W1, W2, W3, and W4) variables declared as float variables. The program will utilize the standard mathematical formula of obtaining area of a rectangle: A = L*W. As well, the formula will be coded in the program as Area=length*width (A=L*W) respectively for each room.
L1 = length of first room, as float
W1 = width of first room, as float
A1=L1*W1
L2 = length of first room, as float
W2 = width of first room, as float
A2=L2*W2
L3 = length of first room, as float
W3 = width of first room, as float
A3=L3*W3
L4 = length of first room, as float
W4 = width of first room, as float
A4=L4*W4
B. Program Design – Following the directions in the assignment, clearly write up your problem design in this section and comment your pseudocode.

...Chapter 11- Why are financial markets important to the health of the economy?
Because they channel funds from those who do not have a productive use for them to those who do, thereby resulting in higher economic efficiency.
2- When interest rates rise, how might businesses and consumers change their economic behavior?
Businesses would cut investment spending because the cost of financing this spending is now higher, and consumers would be less likely to purchase a house or a car because the cost of financing their purchase is higher.
3- How can a change in interest rates affect the profitability of financial institutions?
A change in interest rates affects the cost of acquiring funds for financial institution as well as changes the income on assets such as loans, both of which affect profits. In addition, changes in interest rates affect the price of assets such as stock and bonds that the financial institution owns that can lead to profits or losses.
4- Is everybody worse off when interest rates rise?
No. People who borrow to purchase a house or a car are worse off because it costs them more to finance their purchase; however, savers benefit because they can earn higher interest rates on their savings.
5- What effect might a fall in stock prices have on business investment?
The lower price for a firm’s shares means that it can raise a smaller amount of funds, and so investment in plant and equipment will fall.

Q1-4 (pg. 23)
Profit maximization and maximizing shareholder wealth could conflict. For example, a company could accept very high return (and also very high risk projects) that do not return enough to compensate for the high risk. Profits, or net income, are accounting numbers and therefore subject to manipulation. It would be possible to show positive profits when shareholder wealth was actually being decreased.

a. Operating cash flow = EBIT – Taxes + Depreciation
= $4,500 – $1,300 + $1,600
= $4,800
b. Free cash flow = OCF – D FA – (DCA – DA/P – DAccruals)
= 4,800 – (31,500 – 30,100) – [(16,200 – 14,800) – (3,600 – 3,500) – (1,200 – 1,300)]
= $2,000
c. Operating cash flow (OCF) is higher than free cash flow (FCF) because operating cash flow does not account for investments made during the year. Free cash flow not only looks at operations but...

...HOMEWORKASSIGNMENT1. Callaghan Motors’ bonds have 10 years remaining to maturity. Interest is paid annually, they have a $1,000 par value, the coupon interest rate is 8%, and the yield to maturity is 9%. What is the bond’s current market price?
PV factor of sum = (1+i)^-n
= (1+9%)^-10
=1.09^-10
= 0.4224
PV factor of annuity = 1 - (1+i)^-n / i
= 1 - (1+9%)^-10 / 9%
= 1 - 0.4224 / 9%
= 0.5775 / 9%
= 6.417
= PV factor of Sum * Par Value + PV factor of annuity * coupon payment
= 0.4224 * 1,000 + 6.417 * 80
= 422.4 + 513.3
= 935.76
