  1. A bird species in danger of extinction has a population that is decreasing exponentially (A = A0ekt). Five years ago, the population was at 1400 and today only 1000 of the birds are alive. Once the population drops below 100, he situation will be irreversible. When will this happen?

  2. According to the U. S. Bureau of the Census, in 2000 there were 35.3 million residents of Hispanic origin living in the United States. By 2010, the number had increased to 50.5 million. The exponential growth function A = 35.3ekt describes the U.S. Hispanic population, A, in millions, t years after 2000.

a. Find k, correct to three decimals places.

b. Use the resulting model to project the Hispanic resident in population in 2015.

c. In which year will the Hispanic resident population reach 70 million?

An investor is considering purchasing one of three stocks. Stock A is regarded as conservative, stock B as speculative, and stock C as highly risky. If the economic growth during the coming year is strong, then stock A should increase in value by $3000, stock B by $6000, and stock C by $15,000. If the economic growth during the next year is average, then stock A should increase in value by $2000, stock B by $2000, and stock C by $1000. If the economic growth is weak, then stock A should increase in value by $1000 and stocks B and C decrease in value by $3000 and $10,000, respectively.

(a) Give the pay off matrix for this problem and decide if the game is strictly determined or not.

(b) What is the optimal strategy for the investor?

(c) What is the value or expected value of the game?

Exercise 4–Timing Sorting AlgorithmCollect the run times for either selection sort or insertion sort (use random values for an array and sorted values; sorted the same list twice and collect time each time) for the following array sizes: 1000, 2000, and 10000. You should be able to confirm that the runtime is n^2 for unsorted list (i.e., going from 1000 to 2000 should be about 4 times slower and going from 1000 to 10000 should be about 100times slower).

Question 1: Does your sorting algorithm in exercise4run faster for a sorted listthan an unsorted list?Explain why or why not.

Question 2: What are some reasons for doing algorithm analysis and expressing running time in O notation?

  1. Assuming standard 1500 byte Ethernet max payloads: how many IPv4 fragments will be needed to transfer 2000 bytes of user data with a single UDP send? And, how do the 2000 bytes get split over the frags?
  2. Despite its conceptual elegance, RPC (Remote Procedure Call) has a few problems. Discuss any 3 of those in brief.
  3. Why is timestamping needed in real-time applications? This is in the context of Real-time Transport Protocol (RTP).
  4. Why does UDP exist? Would it not have been enough to just let user processes send raw IP packets?
  5. Explain how QUIC eliminates a couple of RTTs usually needed at the start of a secure web connection.

On January 1, 2018, Bishop Company issued 10% bonds dated January 1, 2018, with a face amount of $20 million. The bonds mature in 2027 (10 years). For bonds of similar risk and maturity, the market yield is 12%. Interest is paid semiannually on June 30 and December 31.

Required:

1. Determine the price of the bonds at January 1, 2018.

2. Prepare the journal entry to record the bond issuance by Bishop on January 1, 2018.

3. Prepare the journal entry to record interest on June 30, 2018, using the effective interest method.

4. Prepare the journal entry to record interest on December 31, 2018, using the effective interest method.

On January 1, 2018, Essence Communications issued $900,000 of its 10-year, 6% bonds for $777,687. The bonds were priced to yield 8%. Interest is payable semiannually on June 30 and December 31. Essence Communications records interest at the effective rate and elected the option to report these bonds at their fair value. On December 31, 2018, the market interest rate for bonds of similar risk and maturity was 7%. The bonds are not traded on an active exchange. The decrease in the market interest rate was due to a 1% decrease in general (risk-free)interest rates. (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of $1 and PVAD of $1)

Required:
1. Using the information provided, estimate the fair value of the bonds at December 31, 2018.
2. to 4. Prepare the journal entry to record interest on June 30, 2018 (the first interest payment), on December 31, 2018 (the second interest payment) and to adjust the bonds to their fair value for presentation in the December 31, 2018, balance sheet.

1.

Present Value of the bonds ?

2. Record the interest expense on June 30, 2018
3. Record the interest expense on December 31, 2018
4. Record the fair value adjustment December 31, 2018
