Write an application (including algorithm) that uses a “void” function (CalculateHypotenuse) to calculate the hypotenuse of a right triangle.The function uses three formal parameters (i.e., side1 [pass by value], side2 [pass by value], hypotenuse [pass by reference]).The function calculates the hypotenuse using the “Pythagorean theorem”.

The application requires a sentinel controlled loop where program prompts for continuing and expects an entry of ‘Y’ or ‘y’ using the variable “cont”.Within the loop, the application provides for allowing the user to enter the length of the sides of the triangle, calls the function and displays the value of the hypotenuse.

Note: Keep in mind the 3 requirements for functions

## BUSI 3004 WU Wk 3 Relationships in Marketing & Financial Plans Discussion Business Finance Assignment Help

Discussion – Week 3

It is important that entrepreneurs investigate all the components of the business plan as they begin planning for a new venture. This requires studying the relationship among the marketing, operational, and financial plans and how they will be affected by this new product or service.

What is the relationship among the marketing, operational, and financial plans? How can you ensure that they are accurately aligned?

With these thoughts in mind: No less than 200 words:

Write a 3 – 4 paragraph that explains the relationship among the marketing, operational, and financial plans emphasizing their accurate alignment.

Please read and view this week’s Learning Resources before you complete the Discussion.

• Course Text: Hisrich, R.D., Peters, M.P., & Shepherd, D.A. (2020). Entrepreneurship (11th ed.). New York: McGraw-Hill Irwin.

Chapter 8, “The Marketing Plan”

In this chapter, you will be introduced to the concept of developing a marketing plan. You will investigate the necessity of conducting research through industry and competitive analysis to effectively market the product being produced. You will follow the steps to preparing the marketing plan and generate ideas for creatively marketing a product.

Focus on the definitions provided throughout the chapter. Review and think about the examples and anecdotes provided in the chapter that illustrate the major ideas being conveyed. Think about clever marketing strategies that have caught your attention in the past. What makes them stand out in your mind, and how could you generate this creativity for another venture?

Chapter 9, “The Organizational Plan”

In this chapter, you will learn about the importance of a strong management team when developing a new venture. Although the idea for a new venture may be held by one individual, preparing a team to launch the venture is necessary to its success. You will learn how the informal organizational plan is as important as the formal one. Finally, you will see how a board of directors or advisors can lend an objective eye and support a management team.

Focus on the definitions provided throughout the chapter. Review and think about the examples and anecdotes provided in the chapter that illustrate the major ideas being conveyed. Consider your past experiences in working or playing with a team. Generally, are you more successful when working as a part of a team or individually?

Chapter 10, “The Financial Plan”

Balanced budgets can either make or break an organization. You will learn how positive profits can lead to negative cash flow as you investigate solutions to this type of situation. When studying the financial viability of an organization, you must look at the break-even point to decide cost values for the product. Lastly, you will look at software packages that can ease the stress of creating the necessary financial documents.

Focus on the definitions provided throughout the chapter. Review and think about the examples and anecdotes provided in the chapter that illustrate the major ideas being conveyed. Consider your own financial budget or need for one. How does this budget drive your spending and saving habits?

## Mediating Role of Psychological Mechanisms Linked to Mindfulness Group Proposal Humanities Assignment Help

1. Follow the rubric on pages 17-18 of your syllabus. Use course notes and your group textbook to guide you.
2. You DO NOT have to do this group for real. Conceptualize it as…I am going to give my field instructor a group proposal idea to see if they may want to do this group sometime in the future (it does not have to be you doing the group, it could be any social worker in the agency). I would like you to give this paper to your field instructor when completed. This could be a helpful resource for you down the road, for example, you can then say at job interviews or graduate school applications that you “developed a group proposal for……..” and would like to continue researching options to develop this group. Even if the group never runs, you still developed a proposal and that is noteworthy.
3. You should look for 3 scholarly articles on your group topic. For example, under the “purpose” section, I may discuss three different articles I found about why foster care support groups are helpful for children. Be sure to use APA style.
4. Review the social work theories handouts in the learning modules section of BB to give you some ideas. For example, I might choose a psychoanalytic theory background due to long term childhood trauma issues.
5. Look under the “course information” section on BB for the sample paper I attached. The minimum requirement is 5 pages plus a reference page, however it can be as long as you want it to be.

## SOCW 6204 Walden University WK 7 DB Medical Social Work Discussion Humanities Assignment Help

Religion and spirituality are complex constructs that have the capacity to influence patients’ illnesses, courses of treatment, and experiences. Medical social workers may feel unsure of how to address patients’ religious beliefs. Despite knowledge about the benefits of medications and treatment in illness management, social workers may hear patient comments such as, “I don’t need medicine. God is going to heal me.” In situations of conflicting ideas, it is important for medical social workers to consider the standards and tenets that govern the profession. Medical social workers must listen, not judge, and promote a patient’s self-determination. In addition, they must accept that they may not be able to address a patient’s religious or spiritual needs and call upon colleagues such as pastors, priests, imams, and rabbis who are more qualified in these areas.

To prepare for this Discussion, review this week’s resources. Focus on the religious and spiritual standards set by the National Association of Social Workers. Then, consider your own religious and spiritual bias and worldviews. Think how these might influence your effectiveness as a medical social worker.

Post an explanation of the impact religion or spirituality can have on patients’ perceptions of health and health outcomes. Then, explain how religion and spirituality might influence patients’ experiences of illness, healing, resilience, and death. Explain the potential impact of your personal views about religion or spirituality on providing services to a patient. Finally, explain ways you might improve your understanding of your patients’ views about religion and spirituality. Justify your response by citing scholarly resources. Be specific and use examples to illustrate your points.
