The ratio is 1:8 and 1:64

Since each tile is one sixth of an inch in width and one fourth of an inch in length.

That is L1= 1/4  in addition to W1= 1/6 inches.

The real tiles are one sixth of a foot long and one tenth of a foot wide.

Since 1 foot equals 12 inches, that is in inches and inches. that is L2=2 and W2= 4/3

So, the length of the tile divided by its real length is equal to L1/L2

=(1/4)/2= 1/8

In addition, the relationship between the area of the tile in the model and the real area is given by:

(1/4 x 1/6)/ 2 x 4/3

= 1/64

Second method

Since there is a 1/8 ratio between the width of the model's tiles and their real width

As a result, there is dilatation with a scale factor of 1/8.

X+1 depicts horizontal linear equation as x = -1 and slope = 0.

Given that the slope is 0, it shows a horizontal linear equation.

Every point on a horizontal line has the same y-coordinate.

If two points have the same y coordinate, b, then the line's equation is y=b.

The y-intercept of the horizontal line y=b is the point (0,b). The line y=0 is the only x-intercept for horizontal lines.

Horizontal lines have zero slope.

As a result, in the slope-intercept equation y = mx + b, m = 0. The equation is Y = b, where b is the y-coordinate of the y-intercept.

A line that is perpendicular to the x-axis is referred to as a horizontal line.

The graph of a relation of the form x = 5 is a line parallel to the origin since the value of x never changes.

The means are the same and the standard deviations are different.

There are two lists given for which the means and the standard deviations need to be compared. So we first find the mean and standard deviation of each list one-by-one using the formulas,

Mean = (1/n)∑x

Variance = [(1/n)∑x²]- mean²

Standard deviation = √variance

List A  

x:  1      2     3      4     5      6

x²: 1      4     9    16    25     36

n = 6

Mean = (1/6)[1+2+3+4+5+6] = 21/6 = 3.5

Variance = 1/6[1+4+9+16+25+36] - 3.5² = 15.167-12.25 = 2.917

Standard deviation = √2.917 = 1.71

List B

x:  2    3    3     4     4    5

x²: 4    9    9    16   16   25

Mean = 1/6(2+3+3+4+4+5) = 21/6 = 3.5

Variance = 1/6(4+9+9+16+16+25)-3.5² = 13.167 - 12.25 = 0.917

Standard deviation = √0.917 = 0.9576

Hence the means are the same and the standard deviations are different.

By definite integrals, we find that the area of the region bounded by the functions f(x) and g(x) described in the statement is equal to 4.5 units.

In this problem we must determine the area between two functions, a quadratic equation f(x) and a linear equation g(x).

First, we need to determine the limits of the interval of x-values with the help of a graphing tool, represented by the points of intersection of the two functions.

The points of intersection of the two functions are (x₁, y₁) = (- 5, 4) and (x₂, y₂) = (- 2, 1), respectively. Then, the area is defined by the following definite integral:

[tex]I = \int\limits^{-2}_{-5} {[g(x) - f(x)]} \, dx[/tex]

[tex]I = \int\limits^{-2}_{- 5} {[(- x - 1) - (x + 3)^{2}]} \, dx[/tex]

[tex]I = - \frac{1}{2} \cdot [(- 2)^{2} - (- 5)^{2}] - [(- 2) - (- 5)] - (1 / 3) \cdot [(- 2 + 3)^{3} - (- 5 + 3)^{3}][/tex]

I = - (1 / 2) · (4 - 25) - 3 - (1 / 3) · (1 + 8)

I = - (1 / 2) · (- 21) - 3 - (1 / 3) · 9

I = 21 / 2 - 3 - 3

I = 21 / 2 - 6

I = 21 / 2 - 12 / 2

I = 9 / 2

I = 4.5

The area of the region represented by the definite integral introduced above is equal to 4.5 units.

The statement leads to a contradiction. Correct form is presented below:

The non real roots of the polynomial x³ – 7x² + 15x – 25 = 0 are; 1 + 2i, 1 – 2i

Non real roots are simply imaginary roots.

We are told that the real roots of the equation  x³ – 7x² + 15x – 25 = 0 is 5.

Now, it means that (x - 5) is a factor of the given polynomial. Thus, we can factorize the polynomial as;

(x - 5)(x² - 2x + 5) = 0

Now, to find the non - real roots, we will use quadratic formula on (x² - 2x + 5) to get;

x = [-(-2) ± √((-2)² - (4 * 1 * 5))]/2(1)

A list of fixed fees for services recorded on the encounter form is called the Superbills.

The purpose of encounter forms, often referred to as super bills, is to "document services performed by recording the diagnostic and procedure codes, which serve as the foundation for billing and receipt of payment for services." Every time a patient or customer receives a service, the provider records that service, often into medical claims software that may automate much of the subsequent procedure.

This technique entails coding (procedure codes and, if necessary, diagnostic codes), billing/invoicing, and/or transmission to the patient's or client's insurance provider. For the client's health and treatment plans as well as for proper billing, it is crucial to make sure that the appropriate information is documented. This is why encounter forms are such a crucial component of healthcare.

Equation of the line passing through the point of (-20, 4) and perpendicular to the line [(2x + 5y) = 10] will be [2y = (5x + 108)].

As per the question statement, a line passes through the point of (-20, 4) and is perpendicular to the line [(2x + 5y) = 10].

We are required to determine the equation of the above-mentioned line.

To solve this question, we need to know about the formula to express the point-slope form of a line, which goes as, [(y - y₁) = m(x - x₁)],

where (x₁, y₁) is a point through which the line passes, and "m" is the slope of the line.

Also, we need to know about the mathematical fact that, the product of the slopes of two perpendicular lines equate to (-1), i.e., if (m₁ and m₂) are the slopes of two perpendicular lines, then [(m₁ * m₂) = (-1)].

Converting [(2x + 5y) = 10] into the point-slope form of line, we get,

(2x + 5y) = 10

or, [5y = {(-2x) + 10}]

or, [y = {(-2/5)x + 2}]

Therefore, Slope of the line [(2x + 5y) = 10] is (-2/5).

Hence, slope of the line perpendicular to [(2x + 5y) = 10] is [-1/(-2/5)], i.e.,

Slope of the line perpendicular to [(2x + 5y) = 10] is (5/2).

Now, using [m = (5/2)] and (x₁, y₁) as (-20, 4), equation of the line will be

[(y - 4) = (5/2){x - (-20)}]

or, [(y - 4) = (5/2)(x + 20)]

or, [(y - 4) = (5/2x) + 50]

or, [2(y - 4) = 5x + 100]

or, [(2y - 8) = (5x + 100)]

or, [2y = (5x + 108)]
