Identify three problems in a business and come up with a possible solutions to that business problem that is Information Technology (IT)-related.  

.

1. Use the enum keyword or a C++ class to create a new type Boolean with the two values F and T defined. Use the C++ class/struct keyword and an array to create a list of pairs that cover all possible combinations of the 2 Boolean constants you defined.

2. Extend the same program and implement conjunction and disjunction functionality in a separate library (mylib.h/mylib.cpp). Use your implementation to print truth tables for both.

3. Further extend the same program by adding xdisjunction and negation functionality. Use your implementation to print truth table for both.

4. Use functions developed (conjunction, disjunction, negation ...) in above assignment and implement Example 1.8 (a) Construct the truth table of the proposition (p∧q)∨(∼ p∨∼ q). Determine if this proposition is a tautology. (b) Show that p∨∼ p is a tautology.

5. Use functions developed in mylib (mylib.h/mylib.cpp) separate library (conjunction, disjunction, negation ...) in previous assignments and implement Example 1.9

(a) Show that ∼ (p∨q) ≡∼ p∧∼ q.

(b) Show that ∼ (p∧q) ≡∼ p∨∼ q.

(c) Show that ∼ (∼ p) ≡ p.

Parts (a) and (b) are known as DeMorgan’s laws.

Is the relation R consisting of all ordered pairs (a, b) such that a and b are people and have one common parent: reflexive, irreflexive, symmetric, antisymmetric, asymmetric, and/or transitive? If a property doesn’t hold give a counter-example and state the logical definitions of the properties as you consider them.

1a.Suppose that you pay $100,000,000 dollars for a factory that has an expected life of eight years and no salvage value. If the tax rate is 37.5%, and your EBITDA will be $20,000,000 per year for the next three years, and $36,000,000 for the following five years, what is your IRR? (Hint: EBITDA is the EBIT before depreciation and amortization expenses, which are non-cash.)

1b. For problem above suppose there is a $50,000,000 cash payment that you must make to tear down and clean up the factory in year 9, what’s the IRR?

What factors contributed to the stagflation of the 1970s? How did Volker deal with the high inflation? Did high oil prices cause the stagflation or was it something else? Is the Fed independent? If so, how do our leaders ensure they maintain the best interests of the public? How does Milton Friedman establish his view that inflation is a monetary issue? According to Friedman, do trade unions cause inflation by pushing up wages and the cost of production?

RJM Enterprises is a manufacturer of consumer electronics products. The industry is very competitive, and RJM has seen its profits fall in recent years, including an operating loss of $36,159 last year. RJM was able to turn that around this year by aggressively cutting costs. The summarized financial results for RJM are shown below:

Jim Green, the management accountant at RJM, is analyzing the company’s performance for this year in order to explain to management the specific aspects that drove the company to success. Some of the information Jim obtained follows:

Assume that RJM, for efficiency and to reduce cost, maintains little or no direct materials or work-in-process inventory.

Required:

1. Determine the selling price variance for the current year based on sales dollars. Determine the sales volume variance based on contribution margin.

2. Determine the following variable cost variances:

a. The usage and price variances for direct materials.

b. The efficiency and rate variances for direct labor.

Three former college classmates have decided to pool a variety of work experiences by opening a store near campus to sell wireless equipment to students. The business has been incorporated as University Wireless.
Required: Several transactions occurred in March. Each is described separately in this folder. For each transaction, indicate the accounts that are affected, whether they increase or decrease, and the amount of the increase or decrease.
YOU MUST FOLLOW THE INSTRUCTIONS BELOW. IF YOU DON'T, YOU MAY KNOW THE CORRECT ENTRY BUT THE COMPUTER WILL NOT RECOGNIZE IT AND YOU WILL NOT RECEIVE CREDIT.

- After each transaction description, there are several "Account" submission boxes and corresponding "Amount" submission boxes. To indicate the accounts that you think are affected, choose them from the drop-down menu. But you MUST select them in the order that they are listed in the menu. FOR EXAMPLE, if you think that Cash and Inventory are affected by a particular transaction, you must record the Cash impact first and the Inventory impact second because that is the order in which they are listed in the drop-down menu. If you record the Inventory impact first and the Cash impact second, even if they are the correct accounts and even if you have the correct dollar amounts, your answer will be considered incorrect.

- When you record the dollar amounts, be sure to use a minus sign to indicate a decrease in the account. You don't need to use a plus sign to indicate an increase.

- There are always more "Account" and "Amount" submission boxes available than are necessary. When you have indicated all the accounts that are affected by the transaction, you MUST select "Leave Blank" from the drop-down menu for EACH of the remaining "Account" submission boxes (you can leave the "Amount" boxes blank).

- For transactions 3, 4, 5, and 8, you are given additional instructions. Read them carefully.

- You get 5 tries for each transaction (8 tries for transaction #8).

- The entries for each transaction are worth 2 points (4 points for transaction #8).

Transaction 1

An economy has a Cobb–Douglas production function:

Y=K^α(LE)^1-α

The economy has a capital share of 0.35, a saving rate of 43 percent, a depreciation rate of 3.50 percent, a rate of population growth of 3.50 percent, and a rate of labor-augmenting technological change of 2.5 percent. It is in steady state.

a.) Solve for capital per effective worker (k*), output per effective worker (y*), and the marginal product of capital.

K*=?

y*=?

Find Continuous Sub-Array C++

Problem: Given an unsorted array A of size N of non-negative integers, find a continuous sub-array which adds to the given number. Declare dynamic arrays and use only pointers syntax
(no [ ]’s or (ptr+i) stuff.

    Input will be the number of input values to enter followed by the sum to compare with. Print out the continuous sub-array of values that are equal to sum or the message ‘No sum found’. There may be more than one sub-array to be found in a given input.

Example:

Input: 6 10     First number represents 6 values to enter and 10 is the sum.

3 5 8 2 3 5         6 input values for the array.

Output: 8 2   and 2 3 5     these are continuous sub-array values that sum to 10

Your input data sets: I would create an input file for the following.

6 10

a. Find the price of the bond if its yield to maturity falls to 8%. (Do not round intermediate calculations. Round your answers to 2 decimal places.)

b. What price would be predicted by the duration rule? (Do not round intermediate calculations. Round your answers to 2 decimal places.)

c. What price would be predicted by the duration-with-convexity rule? (Do not round intermediate calculations. Round your answers to 2 decimal places.)

d-1. What is the percent error for each rule? (Negative answers should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to 2 decimal places.)

d-2. What do you conclude about the accuracy of the two rules?

• The duration-with-convexity rule provides more accurate approximations to the true change in price.

• The duration rule provides more accurate approximations to the true change in price.

e-1. Find the price of the bond if its yield to maturity increases to 10%. (Do not round intermediate calculations. Round your answers to 2 decimal places.)

e-2. What price would be predicted by the duration rule? (Do not round intermediate calculations. Round your answers to 2 decimal places.)

e-3. What price would be predicted by the duration-with-convexity rule? (Do not round intermediate calculations. Round your answers to 2 decimal places.)

e-4. What is the percent error for each rule? (Negative answers should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to 2 decimal places.)

e-5. Are your conclusions about the accuracy of the two rules consistent with parts (a) – (d)?

• Yes

• No
