Exercise 20.4 Computing the Break-Even Point (LO20-4, LO20-5, LO20-6)

Signs and Symptoms of Pregnancy

Provide the implications of the given disorder as well as the nursing actions or interventions

1. Water potential is the

(a)difference between pressure potential and osmotic potential.

(b)summation of pressure potential and solute potential.

(c)difference between pressure potential and solute potential.

(d)product of pressure potential and osmotic potential.

(e)combination of turgor pressure and pressure potential.

2. Which of the following are plant secondary metabolites that defense against herbivores? (can choose more than one answers)

(1) Lectins

(2) Cytokinin

(3) Cyanide

(4) Phospholipids

(5) Protease Inhibitors

3. Which of the following is a function mediated by Herbivore-induced plant volatiles (HIPVs)? (can choose more than one answers)

(1) Intoxicate the herbivorous insects

(2) Attract carnivorous insects

(3) Communicate with the neighboring trees

(4) Stimulate insects to lay eggs

Suppose a firm ”moves” from one point on a production isoquant to another point on the same isoquant. For each of the following, briefly explain why it is always true, always false, or uncertain without further information:

1) A change in the level of output

2) A change in the ratio in which the inputs are combined

3) A change in the marginal products of the inputs

4) A change in the rate of technical substitution

5) A change in profitability

The correct answers are always false for 1, and uncertain for 2-5 but I can’t figure out why? (Professor's answers)

Edit: 1 is definition of isoquants; 2-cobb douglas makes true, negative input (diagonal line from origin) allows a constant ratio; 3-cobb true, perfect subs false; 4-same as 3; 5-need cost function to tell

Question 4.

GHI is considering two investment proposals. Estimated cash flows are below. Each will require an initial cash outlay, followed by several years of positive cash flows. Each project will terminate and all assets will be liquidated in year 6. GHI’s WACC is 9%.

1. Calculate NPV, IRR, MIRR, PI, and payback period for each project.
2. These projects are substitutes, so GHI will choose at most one of them. What is your recommendation? Should they go with Project 1, Project 2, or neither? Explain your reasoning.

Exercise 8-9A Computing and recording straight-line versus double-declining-balance depreciation LO 8-2, 8-3

At the beginning of Year 1, Copland Drugstore purchased a new computer system for 85,000. It is expected to have a five-year life and a $15,000 salvage value.

Required
a. Compute the depreciation for each of the five years, assuming that the company uses

(1) Straight-line depreciation. (I had 7000 as the answer but it is incorrect)

2) Double-declining-balance depreciation. (Year 4 and 5 I have incorrect)

Suddy limited is considering investing in one of three potential projects.The details of the three projects being considered are summerized above

Present value factors based on 10% cost of capital for project duration:

year 1 = 0.909

year 2 = 0.826

year 3 = 0.751

year 4 = 0.683

Required :

1- Determine which of the above projects has the shortest payback period

2- Determine which of the above projects has the highest net present value. Assume the cost of capital to be 10%

3- Briefly discuss the merits of the NPV Methods

1. Why was it considered a disaster?

2. What made this flu case different than most flu cases?

3. What actions did public health departments take to make things better?

4. What control measures were used during the influenza pandemic of 1918?

Part 2: Assess the potential of H5N1 avian influenza to become a pandemic strain in humans. Your response must include the following:

1. Where did the disease come from?

2. What causes avian influenza?

3. Can the virus infect humans?

4. What can public health officials do to minimize exposure
