The value of n  is 4, and the regular n-sided polygon becomes a square.

When a square tile, a regular hexagon tile, and an equilateral triangle tile share a common vertex, the total interior angle between them is 360°.

We can represent the interior angle between the sides of the regular n-sided polygon as 360°/n.

In the given problem, the square tile has an interior angle = 90°

The regular hexagon tile has an interior angle = 120°

The equilateral triangle tile has an interior angle = 60°.

The sum of all these interior angles = 270°.

Now equal the sum of interior angles = 360°

360° - 270° = 90° to the total interior angle.

This can be obtained by considering n=4 for the regular n-sided polygon, as the interior angle between sides of a regular 4-sided polygon is 360°/4 = 90°.

Therefore, the value of n  is 4, and the regular n-sided polygon becomes a square.

Did you mean, A square tile, a regular hexagon tile, an equilateral triangle tile, and a regular n-sided polygon tile share a common vertex? There are no gaps or overlaps between the tiles. What is n?

y = x + 2 is the  other equation if its graph has a slope of 1.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

If the y-coordinate of the intersection point of the two equations is 2, and one of the equations is y = 3x + 5,

The other equation must be of the form y = mx + b, where m is the slope of the line and b is the y-intercept.

m=1 is the slope of the other equation.

y = mx + b

2 = 1x + b

b = 2 - 1x

b = 2 - x

So the other equation is y = x + 2.

Hence,  y = x + 2 is the  other equation if its graph has a slope of 1.

The volume of the cylinder is 6.18 [tex]cm^3[/tex].

The volume of a cylinder—which corresponds to how much material can be transported inside of it or immersed in it—determines its density. The volume of a cylinder is calculated using the formula [tex]r^2h[/tex], where r is the radius of the circular base and h is the height of the cylinder. The material might be any substance that can regularly fill the cylinder with liquid or another substance.

Use the following formula to determine a cylinder's volume:

V = π[tex]r^2h[/tex]

where r is the radius of the cylinder (diameter / 2), h is the height of the cylinder, and π is approximately equal to 3.14.

First, find the radius:

r =[tex]\frac{ 1.26}{ 2}[/tex]

r = 0.63 cm

Next, find the volume:

V = π[tex]r^2h[/tex]

V = π[tex](0.63)^2(5.0)[/tex]

V= π * 0.3969 * 5.0

V= 3.14 * 0.3969 * 5.0

V = 6.18 [tex]cm^3[/tex] (rounded to 2 decimal places).

So, the volume of the cylinder is 6.18 [tex]cm^3[/tex].

Answer:

X = -2

Step-by-step explanation:

To find slope, it's

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

You're given two points

First one being (-9, -4) and second one being (x, 7). Both are these are in (x,y) form.

Let's plug it in.

[tex] \frac{11}{7} = \frac{7 - ( - 4)}{x - ( - 9)} [/tex]

^ Solving that, we get...

[tex] \frac{11}{7} = \frac{11}{x + 9} [/tex]

And that's because 7 minus a negative 4 means 7 + 4. Two negatives make a positive.

Now the top is good. 11 = 11.

The bottom says 7 = x + 9

If we were to subtract 9 from both sides... 7-9= -2, so

-2 = x

The equations of the asymptotes of the graph of f(x) = 4/(x + 1) + 11 are;

horizontal asymptote:  y = 11      

vertical asymptote: x = - 1

In analytic geometry, an asymptote of a curve is a line such that the distance between the curve and the line approaches zero as one or both of the x or y coordinates tends to infinity.

In projective geometry and related contexts, an asymptote of a curve is a line which is tangent to the curve at a point at infinity.

The function we are given is expressed as;

f(x) = 4/(x + 1) + 11

The value of y of a quadrilateral is 3.

A rectangle is a quadrilateral with four right angles, meaning that all of its angles measure 90 degrees. Given the information provided, the lengths of the left and right sides of the rectangle are equal to 10 and 2y + 4, respectively.

We also have the lengths of the top and bottom sides equal to 18 and 10 + 2x, respectively. However, we don't need to use the information about x as it does not affect the calculation for y.

To find the value of y, we can use the fact that the length and width of a rectangle must be equal. Therefore, we can set the length equal to the width:

10 = 2y + 4

Now that we have an equation, we can solve for y by subtracting 4 from both sides:

2y + 4 - 4 = 10 - 4

2y = 6

Finally, to find y, we can divide both sides of the equation by 2:

2y / 2 = 6 / 2

y = 3

Elisabeth needs 253 hours and 64/100 of an hour to read 34 books, which is stated as a mixed number in the simplest form as 253 3/5 hours.

In order to calculate the amount of time it takes Elisabeth to read 34 books, we need to calculate the amount of time it takes her to read 1 book first.

Since she reads 15 books in 112 hours, we can divide 112 by 15 to find the amount of time it takes her to read 1 book.

112 / 15 = 7.46

This means that it takes Elisabeth 7.46 hours to read 1 book.

Now we can multiply 7.46 by 34 to find the amount of time it takes her to read 34 books.

7.46 x 34 = 253.64

This means it takes Elisabeth 253.64 hours to read 34 books. Since this is a mixed number, we can convert it to its simplest form by subtracting the whole number from the decimal number and expressing it as a fraction.

253.64 - 253 = 0.64

Therefore, it takes Elisabeth 253 hours and 64/100 of an hour to read 34 books, which can be expressed as a mixed number in simplest form as 253 3/5 hours.

A test sample or the group that undergoes an experimental method is referred to as an experimental group. This group is exposed to modifications in the test's independent variable. The independent variable's values and its effects on the dependent variable are noted. Multiple experimental groups may be present at once during an experiment.

A control group is a subset of the experiment that is kept apart from the other groups so that the independent variable under test cannot affect the outcomes.

The base function before the transformation is f ( x ) = x³

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the base function be represented as f ( x )

Now , the equation will be

The transformed function is represented as p ( x )

The value of p ( x ) = ( x + 2 )³

So , we can see that the function p ( x ) has been shifted horizontally by a factor of 2 units to the left
