Dilation is a type of transformation in which a shape or geometric figure's size is altered while maintaining its relative proportions and general shape.

Dilation is applied by the rule:

(x, y) → (kx, ky), where k is the scale factor

We have

(x, y) = (-2, 3) and (kx, ky) = (-8, 12)

Substitute and solve for k

-8 = -2k and 12 = 3k  ⇒ k = 4

So the rule is

(x, y) → (4x, 4y)

According to the triangle inequality theorem, the measure for the third side can be GE = 6 units, because: A. 3 + 5 > 6, 5 + 6 > 3, and 6 + 3 > 5.

The triangle inequality theorem states that the set of side measurements that will form a triangle will be the set of side lengths whereby the sum of any two sides will be greater than the third side of the triangle.

For example, if a, b, and c are the side lengths of a triangle, then:

Thus, we have the given lengths:

FE = 3 units

FG = 5 units

Therefore, the third side length would be GE = 6 units based on the triangle inequality theorem because:

3 + 5 > 6

5 + 6 > 3

6 + 3 > 5

The solution for the value w is 13 in the equation 8w+8 = 9w-5.

Two rays, referred to as the angle's sides and vertex, come together to form an angle. Angles created by two rays are located in the plane where the rays are located.

Dihedral angles are formed when two planes intersect. The angle formed by the rays lying perpendicular to the two intersecting curves at their point of intersection can also be used to define an angle between two intersecting curves.

Angle is a term used to describe the size of an angle or of a rotation. This metric represents the proportion of a circular arc's length to radius. In the case of a geometric angle, the arc is centred at the vertex and is bound by the sides.

We know that vertical angles of intersection are equal, so here

⇒ (8w+8) = (9w-5)

⇒ 8w+8 = 9w-5

⇒ 9w - 8w = 8 + 5

⇒ w = 13

Angle measure = 8(13)+8

                          = 112°

The probability of randomly drawing 10 cards from a deck and getting exactly 5 spades is 0.0468

Formula Required:

Given a set of n items, a group of k items can be chosen in any of the 'n' ways, where 'k' is the number of possibilities. The order in which the choices are made is not significant.

A typical deck of cards contains 52 cards in total. Therefore, there exist (52, 10) scenarios in which 10 cards could be chosen (without replacement) that are exhaustive, mutually exclusive, and equally likely.

Again, there are 13 spades in the entire deck of 52 cards. The remaining (10 - 5) = 5 cards can be drawn from the remaining (52 - 13) = 39 cards in the deck in (39, 5) ways, and 5 spades can be drawn from the 13 spades in (13, 5) ways.

As a result, there are (13, 5) * advantageous scenarios for choosing exactly 5 spades (39, 5)

Consequently, the necessary probability:

= Favorable number of cases for the event / Total number of all possible cases.

= (13 , 5) * (39 , 5) / (52 , 10)

(n, k) = n! / k! (n-k)!  

= 0.0468

Therefore, the probability of 5 spades will be 0.0468

The required value of XYZ squared would be 3136 which is determined by substituting x = -2, y = 7, and z = -4.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

We have to evaluate xyz squared if x = -2, y = 7, and z = -4.

⇒ (xyz)²

Substitute the values of x = -2, y = 7, and z = -4 in the above expression

⇒ [(-2) × (7) × (-4)]²

Apply the multiplication operation and we get

⇒ (56)²

⇒ 3136

Therefore, the obtained value of XYZ squared would be 3136 if x = -2, y = 7, and z = -4.

As per the question statement, Jamie wrote the recursive formula

[aₙ = {(aₙ₋₁) * 4}, where (a₁ = 2)] to describe a specific geometric sequence.

We are required to determine the first five terms of this sequence.

To solve this question, first we have to determine the values of "n" which goes as (n = 1, 2, 3, 4, 5, 6...)

Now, for (n = 1), (an = a₁ = 2), given in the question statement itself,

And using the question mentioned formula, for (n = 2),

[a₂ = {(a₍₂₋₁₎ * 4}]

Or, [a₂ = (a₁ * 4)]

Or, [a₂ = (2 * 4)]

Or, (a₂ = 8).

Similarly, for (n = 3), [a₃ = {(a₍₃₋₁₎ * 4}]

Or, [a₃ = (a₂ * 4)]

Or, [a₃ = (8 * 4)]

Or, (a₃ = 32).

For (n = 4), [a₄ = {(a₍₄₋₁₎ * 4}]

Or, [a₄ = (a₃ * 4)]

Or, [a₄ = (32 * 4)]

Or, (a₄ = 128).

For (n = 5), [a₅ = {(a₍₅₋₁₎ * 4}]

Or, [a₅ = (a₄ * 4)]

Or, [a₅ = (128 * 4)]

Or, (a₅ = 512)

The value of x that makes ∠U and ∠V a complement of each other is; x = 9

There are different equal angle theorems in math's such as complementary angles, supplementary angles, linear pairs e.t.c

Now, complementary angles are defined as angles that sum up to 90 degrees.

We are given that;

m∠U = 2x°

m∠V = 4m∠U = 4(2x)°

We want to find the value of x that makes ∠U and ∠V a complement of each other.

This means that by the definition of complementary angles, they will sum up to 90 degrees. Thus;

2x + 4(2x) = 90

2x + 8x = 90

10x = 90

x = 90/10

x = 9

The expression when (9x-4) is subtracted from (7x-2) in simplest terms is 2(1-x).

According to the question,

We have the following information:

(9x-4) is subtracted from (7x-2).

(We know that an expression written after the word from should be written first and the expression before it should be written after the sign of subtraction.)

So, we have the following expression:

(7x-2)-(9x-4)

7x-2-9x+4

(We know that the number with the same variables are added or subtracted. For example, 7x is added to -9x.)

-2x+2

Taking 2 as a common factor from these two terms:

2(-x+1)

2(1-x)

Hence, the difference of the two expressions is 2(1-x).

The given function is a graph transformation of the absolute value function.

A function transformation "moves," "resizes," or "reflects" the parent function's graph. Function transformations are classified into three types: Translation, Dilation, and Reflection. Only dilation alters the size of the original shape; the other two transformations change the shape's position but not its size.

Step 1: Parent function y = f₁(x) = |x|

Step 2: f₁(x) is reflected (Reflection) about x-axis to form f₂(x) = -f₁(x) = -|x|

Step 3: f₂(x) is moved to left by 5 units(Horizontal translation) to form f₃(x) = f₂(x + 5) = -|x + 5|

Step 4: f₃(x) is moved up 1 unit (Vertical translation) to form f₄(x) = f₃(x) + 1 = -|x + 5| + 1

The equation of the given graph is:

The graph of the equation y = 2x+1 has been plotted

The equation of the line is

y = 2x+1

The domain is defined as the set of all possible inputs of the function.

The range is defined as the set of all possible outputs of the function

Here the equation is y =2x+1, we have to substitute the different values for the x and find the values of y.

The values of the x will be the domain and the values of the y will be the range

At x= -2

y = 2(-2)+1

= -3

At x= -1

y = 2(-1)+1

= -1

At x= 0

y = 2(0)+1

= 1

At x=1

y = 2(1)+1

= 3

At x=2

y = 2(2)+1

= 5

An arithmetic progression is a sequence in which each number is a fixed amount larger (or smaller) than the one before it. The common difference is the sum in question.

An arithmetic progression is a sequence in which each number is a fixed amount larger (or smaller) than the one before it. The common difference is the sum in question.

By picking two consecutive words in the sequence and deducting the first from the second, we may get the common difference for a particular sequence.

The graph of linear function is a straight line. A function with the formula y=f(x)=ax+by=f(x)=ax+b is said to be linear.

Although not quite the same, arithmetic progressions resemble linear functions.

If the value nn is a full number, then the expression t(n)=2n-4t(n)=2n4 denotes a series, and the graph of this sequence will have distinct points (as shown below).

Answer:

The two equations that passes through (2, -3) and has a slope of five are:

y + 3 = 5(x - 2) and y = 5x - 13

Step-by-step explanation:

For the first equation, you get y equal to itself. To do that, you need to simplify the right side of the equation. For 5(x - 2), you will distribute the 5 to the x and -2, equalling to 5x - 10. Next, we subtract 3 from both sides to cancel out the 3 on the left side. The equation is now y = 5x - 13. The -13 is the y intercept so we start at the point (0, -13). Since the slope goes up by 5 for every one point it moves to the right, it will eventually reach the point (2, -3). In other words, you add 1 to the x value and 5 to the y value. The points will look like this: it starts at (0, -13) and goes to (1, -8) and goes to (2, -3). The second equation is equivalent to the first equation. Hopefully this helps you out!
