irina [24]3 years ago
3 0

Responder:

Por favor, consulte la explicación.

Explicación:

La fórmula general para una ecuación cuadrática viene dada por:

Ax² + Bx + C = 0

Una ecuación cuadrática generalmente un polinomio de grado 2; A, B son valores de coeficiente y C es un valor constante en la ecuación.

Dada la ecuación cuadrática:

x² - 2x - 15 = 0

Dado que, A, B, C se pueden identificar y el polinomio es de grado 2, entonces es una ecuación cuadrática.

Encuentra 2 números cuya suma da - 2 y producto da - 15

Los números son - 5 y +3

x² - 5x + 3x - 15 = 0

x (x - 5) +3 (x - 5) = 0

(x - 5) = 0

(x + 3) = 0

x = 5

O

x = - 3

England has a relatively cool and cloudy climate that is ill suited for grape growing. It can produce 200 units of wine for ever
tresset_1 [31]

Answer:

The Portugal has higher opportunity cost of producing cloth

Explanation:

Data provided in the question:

For England :

Opportunity cost of producing cloth

= (Units of cloth that can be produced) ÷ (Units of wine that can be produced )

= 200 ÷ 400

= 0.5 cloth per wine

For Portugal :

Opportunity cost of producing cloth

= (Units of cloth that can be produced) ÷ (Units of wine that can be produced )

= 200 ÷ 100

= 2 cloth per wine

Hence,

The Portugal has higher opportunity cost of producing cloth

How Country Risk Affects NPV. Hoosier, Inc., is planning a project in the United Kingdom. It would lease space for one year in a
Murrr4er [49]

Answer:

NPV = $11,525.6

Probability the project has negative NPV: 30%

Explanation:

1. When there is no risk:

It is given that the initial British corporate tax rate on income earned by US firms is 40%.

The initial investment: $200,000

<em>The cash flow of Hoosier can be described as following: </em>

+) The addition to the cash flow includes:

  • Pretax earnings: £300,000

+) The subtraction to the cash flow includes:

  • Tax on income (40%): £300,000 x 40% = £120,000

=> The cash flow = 300,000 - 120,000 = £180,000 = 180,000 x $1,6 = $288,000

=> The Present value of the project after one year is:

<em>PV = Cash flow/ [(1 + required rate of return)^ 1 year]</em>

<em>= 288,000/ (1+0.18) = $244,068</em>

=> The Net Project Value is:

<em>NPV1 = ∑PV - Initial investment = 244,068 - 200,000 = $44,068</em>

2. Case 2: The British economy may weaken

The initial British corporate tax rate on income earned by US firms is 40%.

The initial investment: $200,000

<em>The cash flow of Hoosier can be described as following: </em>

+) The addition to the cash flow includes:

  • Pretax earnings: £200,000

+) The subtraction to the cash flow includes:

  • Tax on income (40%): £200,000 x 40% = £80,000

=> The cash flow = 200,000 - 80,000 = £120,000 = 120,000 x $1,6 = $192,000

=> The Present value of the project after one year is:

<em>PV = Cash flow/ [(1 + required rate of return)^ 1 year]</em>

<em>= 192,000/ (1+0.18) = $162,712</em>

=> The Net Project Value is:

<em>NPV 2= ∑PV - Initial investment = 162,712 - 200,000 = -$37,288</em>

<em />

3. Case 3: The British corporate tax rate on income earned by U.S. firms may increase from 40 to 50 percent

British corporate tax rate on income earned by US firms is 50%.

The initial investment: $200,000

<em>The cash flow of Hoosier can be described as following: </em>

+) The addition to the cash flow includes:

  • Pretax earnings: £300,000

+) The subtraction to the cash flow includes:

  • Tax on income (50%): £300,000 x 50% = £150,000

=> The cash flow = 300,000 - 150,000 = £150,000 = 150,000 x $1,6 = $240,000

=> The Present value of the project after one year is:

<em>PV = Cash flow/ [(1 + required rate of return)^ 1 year]</em>

<em>=  240,000/ (1+0.18) = $203,390</em>

=> The Net Project Value is:

<em>NPV3= ∑PV - Initial investment = 203,390 - 200,000 = $3,390</em>

The probability of the case there is no risk = 100% - probability of Case 2 - probability of case 3 = 100% - 30% - 20% = 50%

The expected value of the project’s net present value is:

<em>NPV = probability Case 1 x NPV1 + probability Case 2 x NPV2 + probabilityCase 3 x NPV3 </em>

= 50% x 44,068 + 30% x (-37,288) + 20% x 3,390= $11,525.6

<em>As only the NPV of case 2 are negative, so that the probability that the project will have a negative NPV = probability case 2 = 30%</em>

Assume that interest rates on 20-year Treasury and corporate bonds with different ratings, all of which are noncallable, are as
Elina [12.6K]

Answer:

The question is missing the options which are below:

A Real risk-free rate differences.  

B Tax effects.  

C Default risk differences.  

D Maturity risk differences.  

E Inflation differences.  

The correct answer is option C,default risk differences.

Explanation:

Default risk is the increase in return given to an investor to compensate the investor for the likely losses that may arise due to the inability of the borrower to make funds available to the investor on the maturity date or even in required amount.

Different debt instruments have different default risk depending on their credit rating as rated by international rating agencies.Such rating is a function of many factors,which includes:

Balance sheet position

Profitability

Liquidity strength of the company

Macro-economic factors and some others.

Liquidity refers to the ability of the company to settle obligations such as repayment of bonds and interest  when due.

Invariably,liquidity has a higher impact in determining credit rating as well as default risk of an instrument.
