Spencer took a 9 percent one-year fixed-rate loan to buy a new car. He expected to pay a real interest rate of 5 percent.

Suppose that the demand for steel in Japan is given by the equation Qd S = 1200 – 4PS + PA + PT, where QS is the quantity of ste

timurjin [86]

Answer: See explanation below for answer.

Explanation:

a) In equilibrium the quantity supplied will equal the quantity demanded in all three markets. Algebraically this implies:

Qd S = Qs S

Qd A = Qs A

Qd T = Qs T

Substituting in the given curves implies:

1200 - 4PS + PA + PT = 4PS

1200 - 4PA + PS + PT = 4PA

1200 - 4PT + PS + PA = 4PT

Solving the first equation for PT and substituting into the second equation implies:

1200 - 4PA + PS + (8PS - PA - 1200) = 4PA

9PS = 9PA

Cancel 9 on both sides, we have:

=> PS = PA

Substituting these results into the third equation implies:

1200 - 4(8PA - PA - 1200) + PA + PA = 4(8PA - PA - 1200)

=> 10800 = 54PA

=> PA = 200

At:

PA = 200

PS = 200

PT = 200

The equilibrium quantities are:

QA = 800

QS = 800

QT = 800

b) Substituting the new supply curve for steel into the equilibrium condition, we have:

1200 - 4PS + PA + PT = PS

1200 - 4PA + PS + PT = 4PA

1200 - 4PT + PS + PA = 4PT

Again solving for PT in the first equation and substituting into the second equation, we have:

1200 - 4PA + PS + (5PS - PA - 1200) = 4PA

=> 6PS = 9PA

=> PS = 1.5PA

Substituting these results into the third equation, we have:

1200 - 4(5(1.5PA) - PA - 1200) + 1.5PA + PA = 4(5(1.5PA) - PA - 1200)

=> 10800 = 49.5PA

=> PA = 218.18

At:

PA = 218.18

PS = 327.27

PT = 218.18

At these prices, the equilibrium quantities are:

QA = 872.72

QS = 327.27

QT = 872.72

The shift in the supply of steel raises the equilibrium price for all three goods, lowering the equilibrium quantity of steel and raising the equilibrium quantities of aluminum and titanium. This last effect comes as a result of the demand curves for aluminum and titanium increasing in response to the shift in the steel supply curve.

c) Returning to the original equilibrium, this shift in the demand for aluminum implies:

1200 - 4PS + PA + PT = 4PS

1500 - 4PA + PS + PT = 4PA

1200 - 4PT + PS + PA = 4PT

Solving the first equation for PT and substituting into the second equation, we have:

1500 - 4PA + PS + (8PS - PA - 1200) = 4PA

=> 9PS + 300 = 9PA

=> PS = PA - 33.33

Substituting these results into the third equation, we have:

1200 - 4(8(PA - 33.33) - PA - 1200) + (PA - 33.33) + PA = 4(8(PA - 33.33) - PA - 1200)

=> 12900 = 54PA

=> PA = 238.89

At:

PA = 238.89

PS = 205.56

PT = 205.56

At these prices, the equilibrium quantities are:

QA = 955.56

QS = 822.24

QT = 822.24

An increase in the demand for aluminum will raise the equilibrium prices and quantities in all three markets. The price and quantity in the steel and aluminum industries increase because as the price of aluminum rises, the demand for steel and titanium increases.

Westkost [7]

Voluntary organizations that survive on dues and small contributions from a mass membership often do best when the political climate is worst because citizens want to have faith in something.

SCVO defines voluntary organizations as non-profit pushed, non-statutory, self-sufficient and run through those who do no longer receives a commission for running the enterprise. a few voluntary companies are recognized through the Inland revenue as charities.

The purpose of voluntary organizations is to fulfil their challenge and work in the direction of the greater right in some precise manner, as opposed to to make a profit. This often method they prioritize things differently than a enterprise would do.

Examples of organizations within the voluntary quarter consist of: Charities: global imaginative and prescient, American pink pass, and YWCA. Foundations: David Suzuki Foundation, invoice and Melinda Gates basis. Social Welfare companies: Human Rights Watch, Environmental protection employer (EPA)

How will you close skill gaps between what you feel you possess and what employers perceive you have? Multiple Choice be motivat

Mazyrski [523]

<h2>Be motivated to learn</h2>

Explanation:

be motivated to learn : This would be right choice. The reason is that, the gap is because we need to learn some more to reach the expectation of employer. So learning should be life long.

share diverse experiences: Sharing experience does not fill the gap, only proving fills it.

have a high level of energy and an orientation toward action: This seems to be closer, but learning stands first and then putting into action.

believe in personal control of destiny: Self-belief is always essential, but only learning can fill the gap.

seek high levels of achievement: High level of achievement can be done only through learning.

11. Effective communication with patients and co-workers is an important skill for practice managers. Describe what you will do

kolbaska11 [484]

Answer:

The dos and donts in excersing active listening

Explanation:

Active listening helps someone understand what the party is trying to say, even if the message is unclear or ambiguous. As a practice manager, the following actions will enhance or undermine active listening.

Nod in agreement
Maintain eye contact
Offer positive reinforcement with phrases such as 'yes,' ' great' or 'indeed.'
Positive body posture such as facing the speaker and smiling
Ask relevant questions
Seek clarification

Avoid noise: switch off audio devices such as radio, computers while listening.
Do not interrupt or cut off the speaker.
Avoid receiver biases. Keep an open mind, and don't judge the speaker's message before its communicated.
Avoid listener's appreciation: Don't fear that you might not understand the speaker's message.
Keep off distractions such as picking phone calls and reading.
