We can use breadth-first search to find the length of longest simple path in the BFS tree
starting at s by the simple method of checking each v.d value at the end of the algorithm. BFS is
Θ(|V | + |E| and this adds only Θ(|V |) work.
Find an even easier approach that adds only constant time (Θ(1)) work via a simple modification to
the BFS algorithm.

1. a Explain circumstances in which it is responsible to improve maintainability to counteract poor reliability and identify circumstances where this approach is unrewarding.

b the expression for steady-state availability of a single element is:

A(t) = µ/(λ+µ)

Explain what is meant by a steady state. State the meaning of meanings of the symbols µ and λ, and the assumptions inherent in the expression.

Bank of America got bailed out, but Lehman Brothers was allowed to fail. The insurance company American International Group (AIG) was rescued, but in July federal authorities refused to bail out a significant lender to small and medium-sized businesses, the CIT Group (not to be confused with Citigroup, which did get bailed out). What is the logic behind these decisions? Who is being bailed out—and who should be? Was the AIG bailout necessary in your view?

QUESTION ONE

Mila, a travel consultant, was doing her shopping at the local supermarket, Buckleys. When walking in the milk and dairy section in Buckleys, Mila slipped on the floor and hit her knees on a trolley.

While on the floor, Mila looked at the bottom of her shoes and found some squashed cheese which had fallen from the refrigerated display shelves.

Ben, an employee of Buckleys, came to help Mila. Ben told Mila that he was on his tea break and didn’t have the time to clean up the cheese that had fallen onto the floor.

Mila admitted that she was not looking at the floor as she walked, and told Ben, “I was looking around for items to purchase”.

Due to her falling and hitting her knees on the supermarket trolley, Mila suffers from soft tissue injuries and is not able to sit or walk for a long time. Mila’s injuries have become worse due to her taking up binge eating as a means of dealing with her symptoms. Mila is claiming compensation for medical expenses, economic loss and domestic assistance.

REQUIRED:

Advise Mila as to whether she would be successful in negligence against Buckleys supermarket. Please explain fully, using relevant legal authority.

QUESTION TWO

On the 2^nd of March, Jack offers to sell his collection of Persian rugs to his friend Liam for $30,000 by telephone. This was considerably less than the $50,000 that Jack had advertised his collection for in the local newspaper. Liam asked for a little time to think it over and was told by Jack: “Sure, I will leave the offer open until Tuesday the 5^th of March”.

On Monday the 4^th of March, Liam sends Jack an email agreeing to buy the Persian rugs at the specified price subject to Jack’s assurance that the rugs were genuine, hand-made rugs.

Later that same Monday, Jack was approached by Zoe who offered to purchase Jack’s Persian rugs for $50,000 as advertised in the newspaper. Jack immediately accepted Zoe’s offer and then sent Liam a text message withdrawing his offer to sell the rugs to Liam.

Jack read Liam’s “agreement” email on Tuesday the 5^th of March and Liam read Jack’s withdrawal text message on Wednesday the 6^th of March.

REQUIRED:

Advise Jack whether he has an enforceable contract with either Liam or Zoe.

Again, Inc. bonds have a par value of $1,000, a 29 year maturity, and an annual coupon rate of 12.0% with annual coupon payments. The bonds are currently selling for $1,177.

The 2017 balance sheet of Kerber's Tennis Shop, Inc., showed $3 million in long-term debt, $700,000 in the common stock account, and $6.1 million in the additional paid-in surplus account. The 2018 balance sheet showed $3.55 million, $915,000, and $8 million in the same three accounts, respectively. The 2018 income statement showed an interest expense of $380,000. The company paid out $600,000 in cash dividends during 2018. If the firm's net capital spending for 2018 was $750,000 and the firm reduced its net working capital investment by $185,000, what was the firm's 2018 operating cash flow, or OCF?

A. $-1,685,000

B. $-3,450,000

C. $-1,120,000

D. $-2,320,000

E. $2,055,000

Compared to a job, a career:

a. Celsius and Fahrenheit scales have zero values. Why are they not ratio scales?

b. Provide an example of an interval scale not mentioned in the text that is not a ratio scale. If you scale has a zero element, briefly explain why the zero element does not make it a ratio scale.

c. Provide an example of a ratio scale not mentioned in the text. Briefly explain why the zero element of your scale makes it a ratio scale.

What is a proper Christian response to poverty? Is giving money the answer? What would you suggest American Christians do?

This rubric element wants you to look at the policies in place at the start of your chosen decade.

•You will need to provide details on the policies and examine how they were related to macroeconomic issues at the time. Your slide(s) on this will highlight the key points and your speaker notes will add the explanatory detail needed.

•You may need to take a peak at what was happening in the years leading up to the start of your decade.

I need an explanation on the above for the period of 1990-2000. Any help would be appreciated. Thank you!

Consider a modification to the DFS procedure such that it returns for an undirected graph
G, the connected components of G. To do this, you will modify the DFS procedure to
• maintain a counter i, initially set in 1, that counts how many connected components we found so
far; and
• on each vertex v ∈ G.V maintain an attribute component indicating to which connected component
number v belong to. That is, when DFS terminates, v.component indicates the component number
1, 2, . . . i that v belongs to.
Answer the following questions:
(a) Write the pseudocode for this slightly modified version of the DFS algorithm
(b) Explain why your algorithm is correct and its running time. You do not need to provide a formal
argument for correctness, but be sure to explain in clear terms.
