1. Consider Consumers A, B, and C with the following preferences over two goods.

U_A (x₁,x₂) = x₁²x₂³

U_B (x₁,x₂) = 2x₁+3x₂

U_C (x₁,x₂) = min{2x₁,3x₂)

The prices given are p1, p2 and income for each consumer is m.

Solve for the Engel curves for each consumer.

please be very detailed, thank you!

Consider two solutions, the first being 50.0 mL of 1.00 M CuSO4 and the second 50.0 mL of 2.00 M KOH . When the two solutions are mixed in a constant-pressure calorimeter, a precipitate forms and the temperature of the mixture rises from 21.5 ∘C to 27.7 ∘C .

From the calorimetric data, calculate ΔH for the reaction that occurs on mixing. Assume that the calorimeter absorbs only a negligible quantity of heat, that the total volume of the solution is 100.0 mL , and that the specific heat and density of the solution after mixing are the same as that of pure water.

1. Add the function int getNodeLevel (T value) to the Binary Search Tree class provided below. The function should return the level of the node value in the Binary Search Tree.

Hint:

Set currentNode to root

Initialize level = 0

while currentNode != Null

         if currentNode element = value return level

         else move to either the right child or the left child of the currentNode, update the loop, and repeat the loop

Function should return -1 if value is not in the tree

1. Rwanda is an example of how colonialism can be good sometimes. The social structure supported by colonial powers was important in maintaining peace after Rawanda’s independence.

2. The reason some countries are developed, while others are not, is straightforward.

3. Imagine that I am looking-up values in the A column using values on a table E3:F10. VLOOKUP(A1, $E$3:$F$10,2,TRUE) MAY NOT work in practice.

4. Under the False-Paradigm model, development can be achieved by having students from poor countries earn their education in the developed world.

Most government interventions are designed to modify market outcomes, and the aim is usually to improve economic welfare. However, some interventions are specifically motivated purely by political considerations. For this task, we will consider political intervention in the labour market in Venezuela. This case study comes from the article by: Chang-Tai Hsieh, Edward Miguel, Daniel Ortega, and Francisco Rodriguez. 2011. The Price of Political Opposition: Evidence from Venezuela’s Maisanta, American Economic Journal: Applied Economics 3: 196–214.

Note that the analysis in this reference is advanced and you do NOT have to read the entire study to complete the assignment. You should, however, read pages 196-198.

1. Figure 1 on page 197 of the Hsieh et al. (2011) article shows that over one million voters who signed a petition to remove President Hugo Chávez from office were discriminated against and experienced a drop in their wages and employment. Use demand and supply analysis to illustrate this situation.

2. With the aid of a diagram, discuss the impact this political event is likely to have had on Venezuela’s production possibilities and economic welfare.

Western State University (WSU) is preparing its master budget for the upcoming academic year. Currently, 12,000 students are enrolled on campus; however, the admissions office is forecasting a 7 percent growth in the student body despite a tuition hike to $80 per credit hour. The following additional information has been gathered from an examination of university records and conversations with university officials:

• WSU is planning to award 160 tuition-free scholarships.
• The average class has 20 students, and the typical student takes 20 credit hours each semester. Each class is four credit hours.
• WSU’s faculty members are evaluated on the basis of teaching, research, and university and community service. Each faculty member teaches five classes during the academic year.

Required:
1. Prepare a tuition revenue budget for the upcoming academic year.
2. Determine the number of faculty members needed to cover classes.
3. Assume there is a shortage of full-time faculty members. Select at least five actions that WSU might take to accommodate the growing student body by selecting an "X" next to the action.
4. You have been requested by the university’s administrative vice president (AVP) to construct budgets for other areas of operation (e.g., the library, grounds, dormitories, and maintenance). The AVP noted: “The most important resource of the university is its faculty. Now that you know the number of faculty needed, you can prepare the other budgets. Faculty members are indeed the key driver—without them we don’t operate.” Are faculty members a key driver in preparing budgets?

quick and easy to answer!
1. suppose you are working in a busy lab with multiple people sharing a given analytical balance. if you are weighing something which you will only have to weigh once, such as weighing out a reagent onto some weigh paper, which you immediately use to make a solution. is it OK to use the balance ' tare or zero function to set the vessel tare to zero? why or why not? if not what should be done instead?
2. now suppose you are weighing something thay you will have to weigh again later. for example suppose you are weighing out some sample into a crucible. later in the procedure you will heat the sample in the crucible to partially decompose it and you will need to know the mass of the material thay remains. is it OK to use the balance's zero fun tin to set the tare to zero? why or why not. if not what should you do instead.

luStar Company has two service departments, Administration and Accounting, and two operating departments, Domestic and International. Administration costs are allocated on the basis of employees, and Accounting costs are allocated on the basis of number of transactions. A summary of BluStar operations follows:

BluStar estimates that the cost structure in its operations is as follows:

Required:

a. If BluStar outsources the Administration Department, what is the maximum it can pay an outside vendor without increasing total costs? (Do not round intermediate calculations.)

b. If BluStar outsources the Accounting Department, what is the maximum it can pay an outside vendor without increasing total costs? (Do not round intermediate calculations.)

c. If BluStar outsources both the Administration and the Accounting Departments, what is the maximum it can pay an outside vendor without increasing total costs?

A 765-kg two-stage rocket is traveling at a speed of 6.10×103 m/s away from Earth when a predesigned explosion separates the rocket into two sections of equal mass that then move with a speed of 2.30×103 m/s relative to each other along the original line of motion.

Part A

What is the speed of each section (relative to Earth) after the explosion?

Part B

How much energy was supplied by the explosion? [Hint: What is the change in kinetic energy as a result of the explosion?]
