What's the process of each one and result? A singer quartet consisting of Angel, Betty, Carlos and Diana wants to practice their singing. However due to the pandemic they decide to do so at a baseball park to keep social distancing. Angel stands on the home plate, Betty goes to third base, Carlos to second base and Diana to first base. While they are getting ready a bird flies along the line joining third base and home, Betty says “That bird is singing at a frequency of 350 hertz”, but Angel says “No, it is singing at 340 hertz.” Soon after the bird leaves the park Diana sings a 440 hertz note, Carlos hears it 0.1 second later and sings a 261 hertz note. Part a Make a drawing of the bird’s flight path along the line joining third base and home, with an arrow indicating the direction of flight, towards home or away from home. Part b Explain why you chose that direction, include any equations that support your explanation. Part c How far is Carlos from Diana? Show your calculations. Part d What is the period of Carlos’ note at 261 Hertz. Include your calculations

1. On Friday March 10th 2017, around 11pm your instructor Mr. Tamba Yaradouno was at O'Hare International Airport in Chicago picking up a relative. At the passengers arrival what they call "Vestibule" or numbered gates, he could not park and waited for long. The area was packed, airport security cars flashing lights everywhere not allowing anyone to park but just enough time to pick up people.

On Friday October 12th 2018 at about same time your instructor was at the same spot of that airport to surprisingly notice that the area was completely empty and sat there for almost two hours.

Explain in your words in two pages including graphs (hand written or typed, Microsoft office word, times new roman, 12 fonds, double spaced):

a. What has happened to the demand curve of tourists visiting Chicago and the USA in general.

b. What could happened to both demand and supply curves of airport jobs, to the international flights into the USA if this trend of tourists decline continue.

Note: Do not include COVID- 19 here, this is the change of the world view of the USA from the Obama administration compared to President Trump and thus the changes of the number of tourists visiting USA

ABC company is considering producing a new range of smartphones that will require it to build a

new factory. Feasibility studies have been done on the factory which cost $5 million. The studies

have found the following:

1. The factory will cost $25 million and will have a useful life of 20 years.

2. The land where the factory will go is currently used as a carpark for workers and it is assumed that the company will have to pay $200000 per year for their workers to park in a nearby carpark.

3. The factory will be depreciated on a straight line basis and will have a salvage value of $0 but it is believed that most of it can be sold for scrap after 20 years for $50000.

4. Due to the nature of the business they are in, they will have to perform some environmental tests to make sure that some of the chemicals they are using are not entering the ground water around the factory. These tests will be performed every 5 years and cost $625000.

5. Through the building of this factory and the selling of the phones it produces, it’s revenue will increase by $5 million in year 1 and remain at this level for the operational life of the factory.

6. The extra costs that the company accrues per year due to the project are $435000 for labour, $50000 for overhead like power and water bills and marketing costs for the new line of phones will be $500000 per year but will decrease by $15000 per year as the phone gains greater penetration.

7. The company’s current cost of capital is 8% per year.

8. The tax rate is 30%.

9. The project requires an initial investment in working capital of $1000000 that is returned

   in year 20.

Use the above information to answer the following.

A. Calculate the free cash flows that come from this project for the 20 years it is operational. ​
