Answer:Fixed expenses are those that do not change regardless of the level of production or consumption. Variable expenses are those that change in proportion to the level of production or consumption.

Based on the table provided, the following expenses can be considered fixed:

$4,640

$10,304

$2,500

$3,998

These expenses could be considered fixed because they do not appear to be directly related to the level of production or consumption. For example, $4,640 could be tuition fees, which remain the same regardless of how many classes a student takes or how much they use campus facilities.

The following expenses can be considered variable:

$3,000

$700

These expenses could be considered variable because they may be directly related to the level of production or consumption. For example, $3,000 could be the cost of books, which may change depending on the number of classes a student takes. $700 could be spending money for daily needs like food, transportation, or entertainment, which would likely vary depending on how much a student spends.

In conclusion, the distinction between fixed and variable expenses is based on the relationship between expenses and the level of production or consumption. The expenses listed above have been categorized as fixed or variable based on this relationship.

The equation of the circle will be x² +y² +7x +11.

A circle is a two-dimensional object made up of points that are spaced out from a given point (center) on the plane by a fixed or constant distance (radius).

The fixed point is referred to as the circle's origin or center, and the fixed distance between each point and the origin is referred to as the radius.

The general form of the equation of a circle is x² + y² + 2gx + 2fy + c = 0.

The equation can be written as:-

( x - x₁)( x - x₂) + ( y - y₁) ( y - y₂)

( x + 4 ) ( x + 3) + ( y + 1) ( y -1)

x² +7x +12 + y² - 1

x² + 7x + y² +11

Hence, the equation of the circle is x² + 7x + y² +11.

Answer:

To calculate the value of X, we first need to calculate the total amount of money Miss Saver will have saved by the time she retires at age 60.

We know that her first payment is $1000, and that every subsequent payment increases by 5%. Using this information, we can calculate the total payments made during the 30 years:

$1000 x (1 + 0.05)^30 = $1000 x 3.3201 = $3320.1

This is the total amount of money Miss Saver will have saved by the time she retires at age 60.

Next, we need to calculate the value of each annual withdrawal over the 20 years of withdrawals.

We know that the effective annual interest rate is 2% perpetually, so we can use the formula for the future value of an annuity:

FV = X * ((1 + r)^n - 1) / r

where X is the annual withdrawal, r is the interest rate (0.02), and n is the number of years (20).

We can use this formula to solve for X:

3320.1 = X * ((1 + 0.02)^20 - 1) / 0.02

X = 3320.1 * 0.02 / (1.02^20 - 1)

X = 3320.1 * 0.02 / 0.1135 = $292.36

Therefore, Miss Saver needs to withdraw $292.36 each year for 20 years to deplete her savings account.

Rounded to the nearest integer, the value of X is $292.

Let t be the time elapsed in hours, starting at 8:00 A.M. So t = 0 at 8:00 A.M. and t = 3 at 11:00 A.M. The distance traveled by the train can be expressed as the definite integral of its velocity with respect to time:

distance = ∫(87 mph) dt from t = 0 to t = 3

Since mph is a unit of speed, we need to convert it to a unit of velocity (feet per second) in order to evaluate the integral:

87 mph = 87 miles/hour × 5280 feet/mile = 454840 feet/hour

distance = ∫(454840 ft/hr) dt from t = 0 to t = 3

distance = 454840 ft/hr * t from t = 0 to t = 3

distance = 454840 ft/hr * 3 hours

distance = 1364520 feet

So, the train travels a distance of 1364520 feet from 8:00 A.M. to 11:00 A.M.

Draw a line connecting the two perpendicular lines, creating a triangle. Calculate the two remaining unknown sukutes, subtract 62 from 180 to get 118 degrees, and divide this by two to get 59 degrees.

What are perpendicular lines?

Perpendicular lines are described in geometry as line segments that join or overlap at right angles. The word 'perpendicular' comes from the Latin word 'perpendicularis,' which means a plumb line.  If two lines AB and CD are parallel, we may express them as AB and CD. The sign indicates that the lines are perpendicular.

Step 1: Draw a line from the center of the windshield to the left side of the windshield. This line should be 90 degrees.

Step 2: Draw another line perpendicular to the first line, going from the center of the windshield to the right side of the windshield. This line should also be 90 degrees.

Step 3: Draw a line connecting the two perpendicular lines, creating a triangle. This line should be 62 degrees.

Step 4: Calculate the two remaining unknown sukutes. To do this, subtract 62 from 180 to get 118 degrees. Then divide this by two to get the two remaining unknown sukutes, which should both be 59 degrees.

Sharon needs to receive a score of 43 on the final to have an average score of 80.

Step-by-step explanation:

First, let's understand what is being told to us. We are being asked to find the score Sharon needs on the final, or x. Since the final is worth 2 tests, the final is equal to twice the score she receives, or 2x. Next, we need the average of all the tests, including the final, to be equal to 80. It's important to also note that we will be taking the average of 6 scores. Now, let's use all of our information to write an equation to solve:

( 77 + 84 + 72 + 65 + 96 + 2x ) / 6 = 80.   [Combine like terms]

( 394 + 2x ) / 6 = 80   [Multiply by 6]

394 + 2x = 480   [Subtract 394 from both sides'

2x = 86   [Divide both sides by 2]

x = 43

tan56° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{3.2}[/tex] ( multiply both sides by 3.2 )

3.2 × tan56° = x , then

x ≈ 4.744

using the cosine ratio in the right triangle on the right

cos67° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{w}[/tex] = [tex]\frac{4.744}{w}[/tex] ( multiply both sides by w )

w × cos67° = 4.744 ( divide both sides by cos67° )

Equation for charges of first plan

C₁ = 24.t

Equation for charges of second plan

C₂ = 9t + 2995

If we talk for _199.7__ minutes the two plans will cost the same.

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

Given,

First plan charges rate of 24 cents per minute

C₁ = 24.t

C₁ is the charge of first plan

t is the number of minutes

Second plan charges $29.95 plus 9 cents per minute.

C₂ = 9t + $29.95

1 dollar = 100 cents

C₂ = 9t + 2995

Where C₂ is the charge of first plan

t is the number of minutes.

Let after x minutes the cost of both plans will be same

C₁ = C₂

24x = 9x + 2995

24x - 9x = 2995

15x = 2995

x = 2995/15

x = 199.667 ≈ 199.7 minutes

Hence, C₁ = 24.t and C₂ = 9t + 2995 are the equations for the charges of first plan and second plan respectively.

After talking 199.7 minutes the cost of two plans will be same.

The inverse Laplace transform of (2/(s+5)) is f(t) = 2 * e^(-5t)u(t).

To find the inverse Laplace transform of F(s) = (2/(s+5)), we can use partial fraction expansion and then use a table of Laplace transforms to identify the inverse transforms.

Step 1: Perform partial fraction expansion on the fraction:

(2/(s+5)) = (2/5) * (1/(1+(s/5))) = (2/5) * (1/1 + (s/5))

Step 2: Recognize the form of the partial fraction as a geometric series, and use the formula for the sum of a geometric series to find the inverse Laplace transform:

The sum of this geometric series is

(2/5) * (1/(1-(-s/5)))

= (2/5) * (1/(1+s/5))

= (2/5) * (5/5+s)

= (2/(5+s))

Step 3: Use the table of Laplace transforms to find the inverse transform of (2/(5+s)):

In a discounted cash flow (DCF) analysis, the interest rate used to calculate the present value of future cash flows is known as the discount rate. This aids in determining if the present-day capital outlay required to fund a project or investment will be greater than the value of the projected future cash flows from that project or investment.

The WACC and adjusted present value are the two main formulas for calculating the discount rate (APV).

WACC = E/V x Ce + D/V x Cd x (1-T) is the formula for the WACC discount, and
