b) GDP is bound within the nucleotide-binding pocket of the GBP

c) the GBP is incapable of hydrolyzing its bound GTP

In terms of decision-making sequences, how would you explain and describe: (a) the 25-year-old, healthy worker who sees the same physician for minor medical needs; (b) the retired individual who calls the state medical society and seeks a second opinion prior to open-heart surgery; and (c) the consumer who searches WebMD to diagnose their condition and then goes to the local pharmacy and speaks to the pharmacist about a possible over-the-counter remedy based on their self-diagnosis.

Opportunity Cost Exercise. Please show how you solved the questions.   

You have been working for your brother (owner of a Down Under Sandwich Shoppe). The franchise company is now offering you a chance to franchise one of their new Big Bird Stick-e-Chicken shops (which sells their honey-roasted chicken-on-a-stick). You estimate your business can gross 45% of Down Under’s $500,000 sales. Shop space is available between Down Under Sandwiches and Little Nero Salads that leases $8,400 a year plus a yearend rent bonus to the property owner of 3% of your gross sales in excess of $200,000.   You intend to invest $20,000 of your own savings (which is presently earning you 6% per annum interest). A bank will loan you $100,000 (annual interest on this loan will be $7000). NOTE: neither the bank loan principle you borrow from the bank nor the $20,000 of your own money you invest is an explicit or implicit cost. However, the interest paid on the bank loan is explicit, and the interest foregone on your savings is implicit. You estimate that hired labor will cost you $70,000 a year, utilities $5,900 a year, and ingredients for the food $100,000 a year. You will have to pay Big Bird, Inc., an annual franchise fee is $3,000 plus 2% of your gross sales for the year. Another 1% of gross sales must be paid for national advertising. You are presently an Assistant Manager at Down Under earning $12,000 a year plus a yearend bonus of 2% of gross (a job you will have to give up), but you do not think you can earn more than this working for yourself, in spite of the extra strain of owning your own business.

1. What is the estimated explicit (accounting) cost of your proposed business? Itemize in detail.
2. What is the accounting profit you project for your business?
3. What is the total implicit cost you estimate for your venture? Itemize in detail.
4. Do you project any economic profit? How much?
5. What is the annual interest rate the bank will charge you for its loan?
6. From the economic profit viewpoint, would this be a viable business to start? Explain:

Please answer all 3 questions and explain . thank you.

(1) Determine the length of the curve y= 3 + 2x^(3/2) for 0 ≤ x ≤ 2. You can use your calculator at the last step (after the integration) to determine the approximate length, or you may keep it exact.

(2) Set up, but do not evaluate an integral for the surface area obtained by rotating the curve y = x^3+ 4, 1 ≤ x ≤ 5 (a) about the x-axis. (b)about the y-axis.

(3)Find the particular solution to the differential equation dy dx = y 2 sin x that satisfies the initial condition y(0) = 3.

2-) The Government observes a significant amount of unemployment in the economy. Some argue that the government should stimulate the economy in order to decrease the unemployment level using monetary policy.

a) Using the theory of liquidity preference, show the effects of expansionary monetary policy. What will happen to the interest rate? What will happen to the aggregate demand as a result? You must explain why we observe this relationship.

b) Draw the new short-run equilibrium of the economy. What happened to the price level, output and the unemployment level in the new short-run equilibrium?

c) How will the economy adjust in the long-run? Explain the transition and show it on a graph. What will happen to the price level, output and unemployment?

d) Show how the same economy will adjust in the short-run and the long-run using a Phillips curve this time. Use the same labels you used for the initial, the short-run and the long-run equilibrium that you used in part c).

e) Would you advise the government to undertake this policy considering your answers to part c) and

d)? Why? What will be happening to the policy options in the long-run? Explain by talking about the trade-off options between unemployment and inflation.

Reflection topic: Netiquette, peer assessment, and feedback

1. We know that using netiquette online is important, but why? What are the consequences of bad netiquette in the classroom? In your response, be sure to reflect on how it feels to be addressed with bad netiquette, and how you think others feel.
   
2. How does netiquette relate to peer assessment? Why is it important to use good manners when leaving feedback?
   
3. How do you feel about the feedback you received this week? What about the feedback you gave?

The Learning Journal entry should be a minimum of 400 words and not more than 750 words. Use APA citations and references if you use ideas from the readings or other sources.
