Discussion:
Your first patient this week has a problem of the genitourinary tract that has plagued him since birth. He has had many hospitalizations due to this problem and suffers repeatedly with difficulties of the genitourinary tract. Describe the problem using terms built from the genitourinary medical word elements in your text. Mention 3 tests or procedures that would help you understand or treat your patient.
The second patient for you this week is a woman with a problem involving the reproductive area. Describe the problem she has with words built from some of the reproductive medical word elements in your text. You need to include at least 3 tests or procedures needed to address her issue as well.

1A. Which equilibrium phase on the Fe-Fe
phase diagram changes to Martensite when cooled quickly enough?
A. Austenite B. Ferrite C. Bainite D. Cementite
1B. For a tapered cross section metal bar that contracts when cooled, what is the stress status when the part is quenched to room temperatures (25 pts)?
A. The edge is in compression and the heavier section is in tension B. The edge is in tension and the heavier section is in compression C. No residual stresses will be built in the component
1C. A cylindrial carbon steel ingot is cooled from austenite temperatures to room temperatures, what is the stress status in the ingot (25 pts)?
A. The surface of the ingot is incompression and the center of theingot is in tension B. The surface of the ingot is in tension and the center is in compression C. No residual stresses will be built in the component

The class Contact, shown below, which hold first names, last names, and mobile numbers.
Using the built-in Java ArrayList<Contact> contacts
Write a method
public static boolean contains(ArrayList<Contact> list, String firstOrLastName)
public class Contact {
private int mobileNumber;
private String firstName;
private String lastName;
public int getMobileNumber() {
return mobileNumber;
}
public String getFirstName() {
return firstName;
}
public String getLastName() {
return lastName;
}
public Contact(int mobile, String first, String last)
{
mobileNumber = mobile;
firstName = first;
lastName = last;
}
}
which returns a boolean indicating whether the list has a entry in which firstOrLastName is in a Contact as either name. Do not use the built-in ArrayList contains method.

Scenario: Kim Weathers, CEO of Southwest Idaho Bank and Trust, has decided to retain the bank’s corporate jet at a time most of the bank’s competitors have sold theirs. The bank has built a reputation for being an expert in taking care of the needs of a diverse, specialized segment of customers such as cattle ranchers in Montana and western Texas as well as almond growers in California. Ms. Weathers has determined that the bank’s executives, including her, need to be able to travel to meet with her clients on short notice, and the only way to be able to do this is to retain the corporate jet.
Stock analysts, wary of the bank’s decision to retain the jet, estimated that the bank generated an additional $26,000,000 in revenue in 2019 that the bank otherwise would not have made if it hadn’t kept the jet. External accountants were able to compute the all-in cost of the jet to the company in 2019 as being $20,000,000. There is no evidence the jet was used on non-official bank business.

Tiger Towers, Inc. is considering an expansion of their existing business, student apartments. The new project will be built on some vacant land that the firm has just contracted to buy. The land cost $1,000,000 and the payment is due today. Construction of a 20-unit office building will cost $3 million; this expense will be depreciated straight-line over 30 years to zero salvage value; the pretax value of the land and building in year 30 will be $18,000,000. The $3,000,000 construction cost is to be paid today. The project will not change the risk level of the firm. The firm will lease 20 office suites at $20,000 per suite per year; payment is due at the start of the year; occupancy will begin in one year. Variable cost is $3,500 per suite. Fixed costs, excluding depreciation, are $75,000 per year. The project will require a $10,000 investment in net working capital. = 10.0% = 11.20% = 15.0% tax rate = 34% = 3 = 24.9% = 2% Assume that the firm will partially finance the project with a $3,000,000 interest-only 30-year loan at 10.0 percent APR with annual payments. What is the levered after-tax incremental cash flow for year 1? What is the levered after-tax incremental cash flow for year 30?

The owner of Brooklyn Restaurant is disappointed because the restaurant has been averaging 7,500 pizza sales per month, but the restaurant and wait staff can make and serve 10,000 pizzas per month. The variable cost (for example, ingredients) of each pizza is$1.55.Monthly fixed costs (for example, depreciation, property taxes, business license, and manager's salary) are $12,000 per month. The owner wants cost information about different volumes so that some operating decisions can be made.

The owner has been considering ways to increase the sales
volume. The owner thinks that 10,000 pizzas could be sold per month
by cutting the selling price per pizza from$6.25 a pizza to
$5.75. How much extra profit (above the current level) would be generated if the selling price were to be decreased? (Hint: Find the restaurant's current monthly profit and compare it to the restaurant's projected monthly profit at the new sales price and volume.) |

Requirement 2. From a cost standpoint, why do companies such as
Brooklyn
Restaurant want to operate near or at full capacity?
Companies want to run at full capacity to better utilize the resources they spend on ▼(average, fixed ,variable costs.) The more units they produce, the▼( higher, lower )the▼( average fixed ,average variable, fixed, variable) cost per unit.
Requirement 3. The owner has been considering ways to increase the sales volume. The owner thinks that 10,000 pizzas could be sold per month by cutting the selling price per pizza from $6.25 a pizza to $5.75.
How much extra profit (above the current level) would be generated if the selling price were to be decreased? (Hint: Find the restaurant's current monthly profit and compare it to the restaurant's projected monthly profit at the new sales price and volume.)
Identify the profit formula and compute the monthly profit at the current and the new volume.
