The value of the unknown lengths in these similar triangles is FH is 6.67 units and EG is 27 units.

A triangle is a polygon with three sides and three angles. It is a two-dimensional shape that is commonly studied in mathematics, geometry, and other fields. The sum of the angles in a triangle is always 180 degrees, and the lengths of the sides can vary. Triangles can be classified based on the lengths of their sides and the measures of their angles. Common types of triangles include equilateral, isosceles, scalene, acute, right, and obtuse triangles. Triangles have many important properties and are used in various applications, including construction, engineering, and physics.

Here,

1. Let x be the length of FH. We have:

AB/EF = BD/FH

12/8 = 10/x

Cross-multiplying, we get:

12x = 80

x = 80/12

x ≈ 6.67

Therefore, FH ≈ 6.67.

2. Let y be the length of EG. We have:

AC/BD = FH/EG

15/9 = 5/y

Cross-multiplying, we get:

5y = 135

y = 135/5

y ≈ 27

Therefore, EG ≈ 27.

Referral sampling is the method used to ensure that convenience samples will have the desired proportion of different respondent classes.

Convenience sampling is a non-probability sampling method that involves selecting participants who are readily available and easily accessible. However, convenience samples may not represent the entire population accurately, as they may introduce biases and lack diversity.

To address this limitation, referral sampling is often employed. Referral sampling involves asking participants from the convenience sample to refer other individuals who meet specific criteria or belong to certain respondent classes. By relying on referrals, researchers can increase the chances of obtaining a more diverse sample with the desired proportion of different respondent classes.

Referral sampling allows researchers to tap into the social networks of the initial convenience sample participants, which can help ensure a broader representation of the population. By leveraging the connections and referrals within the sample, researchers can enhance the diversity and representation of different respondent classes in the study, improving the overall quality and validity of the findings. Therefore, referral sampling is used as a means of ensuring that convenience samples will have the desired proportion of different respondent classes.

Answer:

AZ = 12.80

Step-by-step explanation:

There are 2 triangles in the square XARS. Squares are always congruent, all sides are the same. Given that WT is 6, we can assume that RS is also 6 (because of congruency). RA is is the hypotenuse of the triangle ARS. To find AS, we can plug in the pythagorean theorem 6^2+x=^2=10^2. We end up getting square root of 64 which simplifies to 8. AS is now 8. We also know that ST is 6 since the square WRST has all congruent sides. 8+6=14 gives us line AT. TZ is 8 due to triangle XAR and the congruency theorem. Now we plug in pythagorean theorem to find AZ and we get 8^2+10^2=x^2. After simplifying the square root of 164, we see that AZ is equal to 12.80

The scale factor used is 2.

It is one of the simplest polygon shapes and is commonly used in mathematics and geometry. The sum of the internal angles of a triangle is always 180 degrees.

The vertices of a triangle are the three points in a two-dimensional (2D) or three-dimensional (3D) space that define the corners or corners of the triangle. In a 2D plane, the vertices are typically denoted as A, B, and C, and in a 3D space, they can be represented as (x1, y1, z1), (x2, y2, z2), and (x3, y3, z3) where (x, y, z) are the coordinates of each vertex along the x, y, and z axes respectively. The vertices of a triangle are connected by three line segments, known as edges, to form the sides of the triangle. The combination of the three vertices and the edges connecting them determines the shape and size of the triangle.

To find the scale factor used to dilate triangle ABC to A'B'C', we can compare the corresponding side lengths of the two triangles.

The distance between A(-3, -3) and B(3, 3) is √((3-(-3))^2 + (3-(-3))^2) = 6√2.

The distance between A'(-6, -6) and B'(6, 6) is √((6-(-6))^2 + (6-(-6))^2) = 12√2.

So the scale factor used to dilate triangle ABC to A'B'C' is:

scale factor = length of corresponding side in A'B'C' / length of corresponding side in ABC

            = (12√2) / (6√2)

            = 2

Therefore, the scale factor used is 2.

No, there is no commutative property of subtraction for rational numbers. The commutative property, which states that the order of operands does not affect the result of an operation, does not apply to subtraction for rational numbers.

The commutative property states that the order of the operands does not affect the result of an operation. For addition and multiplication, the commutative property holds true. However, for subtraction, the order of the operands does matter, and thus, the commutative property does not apply.

Let's consider an example to demonstrate this:

Take the rational numbers 3/4 and 1/2.

If we subtract 3/4 from 1/2, we have: 1/2 - 3/4 = (2/4) - (3/4)

= -1/4.

If we subtract 1/2 from 3/4, we have: 3/4 - 1/2 = (3/4) - (2/4)

= 1/4.

As you can see, the results are different when the order of subtraction is changed, indicating that subtraction does not follow the commutative property for rational numbers.

The commutative property, which states that the order of operands does not affect the result of an operation, does not apply to subtraction for rational numbers. Changing the order of subtraction changes the result, making subtraction non-commutative for rational numbers.

The commutative property does not apply to the operation of subtraction with rational numbers. This is because changing the order of the numbers in a subtraction operation will give a different result.

In mathematics, the commutative property refers to the idea that the order in which numbers are used in an operation does not change the result of that operation. This property holds true for addition and multiplication but, unfortunately, it does not hold true for subtraction and division. For example, in subtraction, if we take two rational numbers such as 5 and 3, 5 - 3 is equal to 2, but 3 - 5 equals to -2. As you can see, changing the order of the numbers gives us different results, demonstrating that there is no commutative property of subtraction for rational numbers.

The circle can be described by the equation (x + 3)^2 + (y - 4)^2 = 1. This equation represents all the points (x, y) that are 1 unit away from the center (-3, 4, 1). The plane in which the circle lies is parallel to the xy-plane, yz-plane, and xz-plane, and its equation is z = 1.

1. To determine the equation of the circle, we need to find the equation of the plane first.
2. Since the plane is parallel to the xy-plane, the z-coordinate of any point on the plane will be the same as the z-coordinate of the center of the circle, which is 1.
3. The equation of the plane is therefore z = 1.
4. Now, we can find the equation of the circle in this plane. It will have the form (x - a)^2 + (y - b)^2 = r^2, where (a, b) is the center of the circle and r is its radius.
5. Substituting the given center (-3, 4, 1) into the equation, we get (x + 3)^2 + (y - 4)^2 = 1.

Therefore, the equation of the circle of radius 1 centered at (-3, 4, 1) and lying in a plane parallel to the xy-plane, yz-plane, and xz-plane is (x + 3)^2 + (y - 4)^2 = 1.

Because g(x) is (-2, 0 ) and (0, 4 ). So the slope is 4/2 or 2. Then you can figure out the equation for g(x) which is g(x) = 2x + 4.

f(x) is (0, 4 ) and (2, 0 ) so the slope is 0 - 4 / 2 - 0 which is -4/2 or -2. Then figure out the equation for f(x) which is f(x) = -2x + 2.

Now with the two equations, you can just go through the answers so

f(0) = 2   ->   f(0) = -2(0) + 2 which equals 2.
