Write a recursive program in C++ to compute the determinant of an NxN matrix, A. Your program should ask the user to enter the value of N, followed by the path of a file where the entries of the matrix could be found. It should then read the file, compute the determinant and return its value. Compile and run your program.

1. Recall a work task, hobby, or other activity that you perform regularly.

2. name the activity and list sequentially the actions you do to complete the activity

3. Describe the main differences between doing your activity as you perform it regularly and any variations to those steps you would make to improve your activity.

4. Reflect on the complexity of your list and the number of steps needed to complete the activity:

• Did variation affect your activity?
• If so, did the variation cause your activity to be easier or more difficult?

Case Study

This case study is about the nuclear disaster of Chernobyl in 1984. It covers all the ethical mistakes and aspects involved in the occurring of the disaster. The ethical dilemmas, responsibilities, whistle blowing & cultural norms of engineers are discussed in it.

The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April, 1986 at 1:23:45 AM at the No. 4 nuclear reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR. It is one of only two nuclear disasters rated as INES 7, the maximum severity classification.

The accident started during a safety test on a common Soviet reactor, the RBMK type.

A very large amount of energy was suddenly released vaporizing superheated cooling water and rupturing the reactor pressure vessel in a highly destructive steam explosion. This was immediately followed by an open-air reactor core fire. The core fire released considerable airborne radioactive contamination for about nine days which precipitated onto parts of the USSR and Western Europe, before being finally contained on 4 May 1986. The radioactive contamination dispersed over this period was approximately the same amount as that released during the initial explosion. Thirty-six hours after the accident, a 10-kilometre exclusion zone was created, with the rapid evacuation of 49,000 people, primarily from Pripyat, and this was increased from 10 to 30 km shortly after when a further 68,000 persons were evacuated, including from the town of Chernobyl itself.

From years of research we know what technically went wrong in Chernobyl disaster. Write few things, what “Ethically” went wrong while keeping in mind following points.

Question number 1:

1. Discuss awareness of professional, social and ethical responsibility of engineers in the disaster [CLO1,PLO6]                                                                                                                                          5                                                                               
2. Should the engineers have blown the Whistle? [CLO2, PLO8]                                                              5                                                                 

Question Number 2:

1. Choose different dilemmas in engineering practice of Chernobyl disaster according to ethical behavior? [CLO3,PLO7]                                                                                                                                       5
2. Explain the impact of personality and cultural norms on engineer’s responsibilities in the Chernobyl scenario? [CLO4, PLO6]                                                                                                                         5

3. The partnership has four partners A 2% partner, individual calendar year. B 51% partner, corporation, 6/30 fiscal year. C 30% partner, corporation, 6/30 fiscal; D 17% corporation, 6/30 fiscal. What taxable years may the partnership use under the following alternative situations?
(a) What taxable year(s) may the partnership use?
(b) Suppose C and D use the 4/30 fiscal year instead.
(c) Suppose A is 22%, B is 31%, and C and D use the 4/30 fiscal year.

please please PLEASE show all steps and write out all the work I have been stuck on this problem and I can't figure out where I'm going wrong.

Do all objects in free fall reach terminal velocity because I thought objects in free fall always accelerate with 9.8 m/s/s so why is there a point where they stop accelerating

Consider the titration of a 100mL of 0.100 M HCN by .100M NaOH. (Ka for HCN is 6.2x10^-10) Calculate the pH after 50.0 mL of .100M NaOH has been added

Title: At the 99% confidence level, what is the proportion of teenagers who play tennis?

____ 3.- Out of a sample of 120 teenagers, 14 of them responded YES to the question “Do you play tennis?” To answer the question in the title:

We would calculate a confidence interval centered at p_hat with a margin of error of 2.576*sqrt(0.12*(1-0.12)/120).

We would calculate a confidence interval centered at p with a margin of error of 2.576*sqrt(0.12*(1-0.12)/120).

We would calculate a significance test with z=sqrt(0.12*(1-0.12)/120).

We would calculate a significance test with Ho: p_hat=0.12.

15.  Patients with Clostridium difficile infections have diarrhea and can have severe infections in their peritoneal cavities (peritonitis) and blood (sepsis). The diarrhea and widespread infections result, at least in part, from altered cell adhesions in cells lining the colon.

A.  [2 pts] What type of cells line the colon, and what type of adhesion linking these cells is likely altered in difficile infection?

B.  [4 pts] How could changes to the cell adhesions you listed in part A promote infections in the blood and peritoneal cavity?  Explain your reasoning.
