formulas used to calculate the free cash flow to firm (fcff)?

Answers

(OCF): OCF = Net Income + Depreciation & Amortization - Changes in Working Capital, (CapEx): CapEx = Investment in Property, Plant & Equipment + Investment in Intangible Assets. therefore, (FCFF): FCFF = OCF - CapEx

The Free Cash Flow to Firm (FCFF) is a measure of a company’s cash flow available for distribution to shareholders and debt holders. To calculate FCFF, the following three steps are taken:

1. Calculate Operating Cash Flow (OCF): OCF is calculated by taking net income, adding back depreciation and amortization, and subtracting any changes in working capital.

2. Calculate Capital Expenditures (CapEx): CapEx includes investments in property, plant, and equipment, as well as any investments in intangible assets.

3. Calculate Free Cash Flow to Firm (FCFF): FCFF is calculated by subtracting CapEx from OCF. This figure represents the cash flow available for distribution to shareholders and debt holders.

In 2009 the average weekly wage of men exceeded that of a woman by $162. The um of their average wage equaled $1476. Write and olve a ytem of equation to determine the average wage of men and of women in 2009

Answers

The average wage of men is $819 and of women is $657 in 2009

What is an equation?

An equation is the equality between two algebraic expressions, which have at least one unknown or variable.

Information about the problem:

M = W + 162M + W = 1476M = average wage of menW = average wage of woman

To solve this problem we must establish the equations according to the given data and solve the operations:

M = W + 162                    (1)

M + W = 1476                  (2)

We have two equations with two unknowns, substituting the value (M) in the second equation, we have:

M + W = 1476

W + 162 + W = 1476

162 + 2W = 1476

2W = 1476 - 162

2W = 1314

W = 1314/2

W = 657

Substituting (W) into one of the equations (M) we have:

M = W + 162

M = 657 + 162

M = 819

how to show that the real exponetial sequence for f[k]=f[kt] is f[k]b^k

Answers

The real exponential sequence for f[k]=f[kt] is f[k]=b^k.

What is exponential sequence ?

The exponential function is a mathematical function denoted by f(x)=\exp or e^{x}. Unless otherwise specified, the term generally refers to the positive-valued function of a real variable, although it can be extended to the complex numbers.

The real exponential sequence for f[k]=f[kt] can be shown to be f[k]=b^k by using the definition of exponential functions. If f[k]=f[kt], then f[k]=f[k-1]t and f[k-1]=f[k-2]t, and so on. By substitution, we have:

f[k]=f[k-1]t

f[k-1]=f[k-2]t

f[2]=f[1]t

f[1]=f[0]t

So we can write:

f[k]=f[k-1]t=f[k-2]t^2=...=f[1]t^(k-1)=f[0]t^k

Next, we can define b as f[0] and substitute it into the above equation:

f[k]=b^k

Therefore, the real exponential sequence for f[k]=f[kt] is f[k]=b^k.

Answers

The fractions found in the 2/n table in the Rhind Mathematical Papyrus.

2/7 = (m n 2 ) 1 n (m n 2 )

= (2 7 2 ) 1 7 (2 7 2 )

= (14 2 ) 1 7 (14 2 )

= 7 1 7 + 7 1 14

2/35 = (m n 2 ) 1 n (m n 2 )

= (2 35 2 ) 1 35 (2 35 2 )

= (70 2 ) 1 35 (70 2 )

= 35 1 35 + 35 1 70

2/91 = (m n 2 ) 1 n (m n 2 )

= (2 91 2 ) 1 91 (2 91 2 )

= (182 2 ) 1 91 (182 2 )

= 91 1 91 + 91 1 182

Using the identity (m n 2 ) 1 n (m n 2 ) we can decompose the fractions 2/7, 2/35, and 2/91 into unit fractions. For 2/7, we obtain the decomposition 7 1 7 + 7 1 14, for 2/35 the decomposition 35 1 35 + 35 1 70, and for 2/91 the decomposition 91 1 91 + 91 1 182.

After solving the equation the triangle given in question the 63.8°.

What is triangle?

A triangle is a three-sided polygon with three angles. It is one of the basic shapes in geometry and is very versatile as it can be used to create many other shapes and structures. Triangles are generally classified by the length of their sides, which can be equal (an equilateral triangle), longer in one side than the other two sides (an isosceles triangle) or different in length on all three sides (a scalene triangle). They can also be classified by their angles, which can be acute (the angles are all less than 90 degrees), right (one angle is exactly 90 degrees) or obtuse (one angle is greater than 90 degrees).

x = 63.8°
Using the Law of Cosines, we can calculate the value of x:
x² = 17² + 9² - 2(17)(9)cos(90°)
x² = 289 + 81 - 306
x² = 64
x = √64

an octahedron consists of two square-based pyramids glued together along their square bases to form a polyhedron with eight faces. imagine an ant that begins at the top vertex and walks to one of the four adjacent vertices that he randomly selects and calls vertex a. from vertex a, he will then walk to one of the four adjacent vertices that he randomly selects and calls vertex b. what is the probability that vertex b will be the bottom vertex? express your answer as a common fraction.

Answers

The probability that vertex b will be the bottom vertex will be 1/16

The ant has four equally likely possibilities for his initial step from the top vertex, each heading to one of the four vertices close to the top vertex.

When the ant reaches vertex A, he has four equally likely next steps, each heading to one of the vertices next to vertex A.

Only one of these possibilities, however, will send him to the bottom vertex: the one that brings him straight to the bottom vertex.

As a result, the ant's chance of reaching the bottom vertex after two steps is 1/4 * 1/4 = 1/16.

suppose winston's loud music externalizes a cost onto his neighbor, chloe. suppose winston and chloe decide to solve this problem using the coase theorem. if they are successful, what is a possible result of the execution of this theorem?

Answers

The Coase theorem states that if property rights are well-defined and transaction costs are low, then the allocation of resources will be efficient, regardless of the initial allocation of property rights.

If Winston and Chloe successfully apply the Coase theorem to solve the problem of Winston's loud music externalizing a cost onto Chloe, they may reach a mutually beneficial agreement. This could result in either Winston reducing the volume of his music or compensating Chloe for the cost of the externalization, or a combination of both.

The goal is to reach a solution where the costs and benefits are more efficiently allocated between the two parties.

Suppose that 15 inches of wire costs 75 cents.
At the same rate, how much (in cents) will 9 inches of wire cost?

Answers

Answer: 45 cents.

Step-by-step explanation: We can find the cost per inch of wire by dividing the total cost by the total length of wire:

75 cents / 15 inches = 5 cents/inch

Now that we know the cost per inch, we can find the cost of 9 inches of wire by multiplying the cost per inch by 9:

5 cents/inch * 9 inches = 45 cents.

Answer:45 cents for 9 inches of wire

Step-by-step explanation:

Per every 5 incheses is 0.25 cents 0.75/15=$0.25 and then taking 0.25/5=$0.05 cents. So 1 inch costs 0.05 cents. So multiply 0.05×9=$0.45 cents. 45 cents

Geometry Dilation

Please help!!!!

Answers

Answer:

C' (-2, -2)

D' (-2, 2)

E' (2, 0)

F' (0, -2)

Step-by-step explanation:

A dilation of factor k about the origin is a transformation that enlarges a figure by a factor of k, while keeping the origin fixed.

It means that each point (x, y) on the pre-image is transformed to a new point (kx, ky) in the dilated figure.

Therefore, the rule for a dilation of 2 about the origin is:

(x, y) → (2x, 2y)

From inspection of the given diagram, the vertices of the pre-image are:

C = (-1, -1)D = (-1, 1)E = (1, 0)F = (0, -1)

Applying the dilation rule (x, y) → (2x, 2y):

C' = (2 · -1, 2 · -1) = (-2, -2)D' = (2 · -1, 2 · 1) = (-2, 2)E' = (2 · 1, 2 · 0) = (2, 0)F' = (2 · 0, 2 · -1) = (0, -2)

Answers

Answer:3/2

Step-by-step explanation: just did the test

As all sides have grown by 2/3 times, The scale factor is  2/3. Thus, option A is correct.

What is scale factor?

In its simplest form, a scale factor is the proportion between the model measurement and the actual measurement. The scale factor, as opposed to a scale ratio, does not contrast various measurement units. A model car that is scaled at one-twentieth of its real-world counterpart is said to be that size. The car is also 20 times bigger than the model, according to this statement.

16 feet is the length of a fence. The fence is depicted as being 4 inches tall on a map. Write a ratio comparing the two quantities before attempting to calculate the scale factor of the drawing to the actual fence.

Given triangle side are 6, 6, 8 and scaled triangle is 9,9,12

The corresponding sides are

6/9, 6/9, 8/12

When you simply, we get

2/3, 2/3, 2/3

As all sides have grown by 2/3 times, The scale factor is  2/3. Thus, option A is correct.
