Follow a public traded stock and analyze the changes in stock price. Write a presentation and an executive memo of your findings. Choose one of the following companies:

1. Amazon
2. Alphabet
3. Microsoft
4. Facebook
5. Apple

In your presentation you should:

1. Describe graphically the trend of the stock prices during the last 2 months and, in more detail, during the last 3 weeks.
2. Explain the observed trends
3. Compare the trends with relevant indexes
4. Relate these trends to relevant contextual information (example: Covid crisis).
5. Is the development of the prices positive? Do you consider that an investment done two months ago is good? Explain.
6. Regarding this context, briefly forecast the changes in prices for the next month.

Monash College is purchasing a new telephone system that will last for 4 years. It can purchase the system using one of the following two options

• Option A: An up-front payment of $178,000
• Option B: Monthly payment of $4000 with the first payment to be made now and the last payment to be made 47 months from now.

Question

1. If Monash College can borrow at an annual percentage rate of 5% with monthly compounding, calculate and identify which option the Monash College should choose?
2. In option B, if the monthly payments were made at the end of each month, without calculation briefly explain if your answer to part 2 a) would be different.

Im trying to derive Cp - Cv = R where Cp and Cv are the molar specific heats at constant pressure and volume respectively. (R = 8.314 J/(mol*K)). So I'm only having problems with the last step.

I get that for a process at constant pressure we have:

∆E(internal) = Q + W = nCp∆T - P∆V

And I get that for a process at constant volume we have:

∆E(internal) = Q + W = Q + 0 => ∆E(internal) = Q

The last step is setting these two equations equal to one another, but I don't understand how we know that the internal energy of both processes are the same.

1. Sheridan Service has a line of credit loan with the bank. The initial loan balance was ​$8000.00. Payments of ​$3000.00 and ​$4000.00 were made after three months and eight months respectively. At the end of one​ year, Sheridan Service borrowed an additional ​$4500.00. Seven months​ later, the line of credit loan was converted into a collateral mortgage loan. What was the amount of the mortgage loan if the line of credit interest was 7​% compounded monthly?

2. A variable rate demand loan showed an initial balance of ​$8000.00​, payments of ​$3500.00 after six​ months, ​$3500.00 after 21​ months, and a final payment after six years. Interest was 7​% compounded quarterly for the first 21 months and 7.2​% compounded monthly for the remaining time. What was the size of the final​ payment?

Charles Lackey operates a bakery in Idaho​ Falls, Idaho. Because of its excellent product and excellent​ location, demand has increased by 25​% in the last year. On far too many​ occasions, customers have not been able to purchase the bread of their choice. Because of the size of the​ store, no new ovens can be added. At a staff​ meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be baked at one time. This new process will require that the ovens be loaded by​ hand, requiring additional manpower. This is the only thing to be changed.  The bakery currently makes 1800 loaves per month. The pay will be ​$8 per hour for employees and each employee works 160 hours per month.

Charles Lackey can also improve the yield by purchasing a new blender. The new blender will mean an increase in his investment. This new blender will mean an increase in his costs of ​$100 per​ month, but he will achieve the same new output​ (an increase to 2250.00 ​) as the change in labor hours. ​

a) Current productivity for 640 work hours​ = nothing ​loaves/dollar ​(round your response to three decimal​ places). If Charles chooses to increase the number of work hours to 800 in order to employ the new oven loading​ technique, then the productivity is​ = nothing ​loaves/dollar ​(round your response to three decimal​ places). ​

b) If Charles instead chooses to purchase a new blender​ (while holding labor constant at 640 hours at ​$8 per ​hour)​, then the productivity is​ = nothing ​loaves/dollar ​(round your response to three decimal​ places).

​c) By adding​ manpower, the percentage increase in productivity is nothing​% ​(enter your response as a percentage rounded to two decimal places and include a minus sign if​ necessary). By purchasing a new blender​ (while holding labor constant at 640 hours at ​$8 per ​hour)​, the percentage increase in productivity is nothing​% ​(enter your response as a percentage rounded to two decimal places and include a minus sign if​ necessary).

Taylor and Michael are agents working for Juarez Real Estate Brokers last September 2018 when one of Jessica’s clients became interested in Michael’s listing. The two write up an option agreement and purchase contract per the terms of their respective clients with the option expiring December 31st, 2020. Due to a wildfire, real estate prices have risen substantially. Describe this arrangement for Juarez’s agency? What is likely to be Taylor’s client’s action?

Write a python programA3) Lambda Expressions. Use lambda expression to sort the list ["democratic", "republican", "equal", "python", "break", "two", "ruby"] by: a) the last 2 characters of each list item in reverse order b) create new list from list above where each item has only 3 characters and first one is capitalized. For example, the list item = "democratic" will transform into "Dem". Apply alphabetically sorting to the new list.
