It should be noted that when the graph of a relationship is a line that passes through the origin, then it is proportional.

A connection is proportional if its graph is a line that goes through the origin. The ratio is not proportionate if it is not a line or ray that doesn't accomplish this. K = y/x is the equation for the proportionality constant. The equation for the slope of a straight line with respect to the origin is the same as this.

A relationship is proportionate if its graph is a line or ray that passes through the origin. It is not proportionate if the line or ray does not go through the origin. Additionally, something is not proportionate if it is not linear.

Answer:

height = x + 6

Step-by-step explanation:

Volume = length x width x height

V = 10x³ + 67x² + 30x − 72

length = 5x - 4 and width = 2x + 3

So length x width =  (5x - 4 ) x (2x + 3)

Using the FOIL method:

= (5x)(2x) + (5x)(3) + (-4)(2x) + (-4)(3)

= 10x² + 15x - 8x - 12

= 10x² + 7x -12

So to find height, divide Volume by (length x width)

10x³ + 67x² + 30x − 72  ÷ 10x² + 7x -12

Use polynomial long division. See image ( I did the best I could to capture the process)

The answer is x + 6

To verify
Multiply (5x-4) (2x + 3) (x + 6) = 10x³ + 67x² + 30x − 72

The student that has the higher standing in the class is Jill

The given parameters are:

Number of students = 200

Jill's position =80th

Nathan's position = Percentile rank  of 80

The above means that

Nathan's position = 80 percentage of the number of students in the class

Substitute the known values in the above equation

So, we have the following equation

Nathan's position = 80 percentage of 200

Rewrite as

Nathan's position = 80 percentage * 200

Express as percentage

Nathan's position = 80% * 200

Express 80% as decimal

Nathan's position = 0.80 * 200

Evaluate the product

Nathan's position = 160

So, we have

Jill's position =80th

Nathan's position = 160th

By comparing the positions, 80th is greater than 160th

Hence, Jill has the higher standing in the class

Answer:

  5/9

Step-by-step explanation:

You want the reduced fraction equivalent to the ratio 40L : 72L.

A ratio is reduced by removing the greatest common factor from all parts of the ratio. Here, that factor is 8L.

  40L : 72L = (8L)(5) : (8L)(9) = 5 : 9 = 5/9

The ratio is 5/9.

__

Additional comment

The greatest common factor can be found several ways. The easiest is for you to make use of your knowledge of multiplication tables:

  40 = 5·8

  72 = 9·8

8 is a common factor. Since 5 and 9 have no common factors, 8 is the greatest common factor of 40 and 72.

The net sales of Shauna's company when she calculated the sales for her company using the figures is $66700.

The total of a company's net sales is its gross sales less any returns, allowances, and discounts. Externally, net sales calculations are not always obvious. They can frequently be taken into account when calculating top-line revenues that are shown on the income statement.

Notice from the graph that data are mostly to the right.

Answer: Option C The distribution is tailed.

In order to rationalize the denominator of the fraction, we need to multiply the fraction by the conjugate of the expression in the denominator.

The conjugate is the same expression but with the signal between the numbers changed.

So we have:

So the new denominator of the fraction is 2, therefore the correct option is D.

3x + 5y = 15 is the equation of the line in standard form that passes through the point (5,0) and (0,3).

The formula for equation of line is expressed as;

y = mx + b

Where m is the slope and b is the y-intercept.

Given the data in the question;

Point 1 ( 5,0 )

Point 2 ( 0,3 )

First, we determine the slope of the line.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Slope m = ( 3 - 0 )/( 0 - 5 )

Slope m = ( 3 )/( -5 )

Slope m = -3/5

Now, we plug the slope and coordinates of one the point into the equation of line to determine the y-intercept b.

y = mx + b

0 = (-3/5)5 + b

Solve for b

0 = -15/5 + b

0 = -3  + b

b = 3

Now that the values of slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.

y = mx + b

y = (-3/5)x + 3

Convert to standard form; Ax + Bx = C

Multiply each term by 5

y = (-3/5)x + 3

5y = 5(-3/5)x + 5(3)

5y = -3x + 15

Reorder the equation

3x + 5y = 15

Therefore, the equation of the line is in standard form is 3x + 5y = 15.

Step-by-step explanation:

equation format: y = mx + b where m is slope and b is the y intercept.

From the points given we find that it is a horizontal line, which means slope or m = 0. So we know so far:

y = 0x + b or y = b

The y-intercept occurs where x = 0. This occurs at y = -7. So the equation for these two points:

By solving the equation, we get the cost of sheet metal =$20 per sq. feet

What is an equation?

An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. The word equation and its cognates in various languages may have somewhat different definitions; for example, in French, an équation is defined as including one or more variables, but in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign. Solving an equation with variables entails finding which variables' values make the equality true. The variables for which the equation must be solved are also known as unknowns, and the values of the unknowns that fulfill the equality are known as equation solutions. Identity equations and conditional equations are the two types of equations.

Given equation 8.2x-3.7x = 90

or, 4.5x = 90

or, x = 90/4.5 = 20

Hence, the cost of sheet metal is $20 per sq. feet

Demonstrating that the limit doesn't exist

What is Limits?

The value that a function approaches when the input approaches a certain value is known as a limit. Calculus and mathematical analysis are not possible without limits, which are used to define continuity, derivatives, and integrals.

The limit exists only if the value of the limit along every direction that leads to (1,1) is same.

So by calculating,

                             lim   xy -x-y + 1 / x^2 + y^2 - 2x - 2y + 2

                             x->1

calculating the limit along the line x = 1

Similarly,

              lim   xy -x-y + 1 / x^2 + y^2 - 2x - 2y + 2

             x->1

calculating the limit along the line y = 1

And the last limit you calculated is along line y=x.

To answer your question, the calculation of the limit along y=1 would not have been necessary. It is sufficient to demonstrate the absence of a limit by giving just two cases in which it appears to vary along several directions.

The definition of the functions implies that the value of x if f(x) = g(x) is 3

The equations of the functions are given as

f(x) = -2x + 4

g(x) = 2x - 8

This means that, we have the following equation

f(x) = g(x)

Substitute the known values in the above equation

So, we have the following equation

-2x + 4 = 2x - 8

Collect the like terms in the above equation

So, we have

2x + 2x = 8 + 4

Evaluate the like terms in the above equation

So, we have

4x = 12

Divide both sides by 4

x = 3

Hence, the value of x such that the equations are equal is 3
