What is the connection between transformations and similar figures?When the sides of two figures are proportionate and the accompanying angles are congruent, the figures are said to be comparable.
Get the two triangles to face in the same direction, or in the same orientation, to check if they resemble one another. You accomplish this by turning one shape so that it is in alignment with the other. A rotation is the name given to such a change.
Similarity refers to two figures that share the same shape but differ in size. A rigid motion and a rescaling make up a similarity transformation. To put it another way, a similarity transformation may change both location and size while maintaining shape.
Let the given points be G(-2, 3), H(4, 3), I(4, 0) and J(1, 0), K(6.-2), L(1, -2).

Answer:
not similar
Step-by-step explanation:
You want to know if ∆GHI ~ ∆JKL when they are defined by coordinates G(-2, 3), H(4, 3), I(4, 0) and J(1, 0), K(6.-2), L(1, -2).
Similar trianglesCorresponding angles of similar triangles are congruent, and corresponding sides are proportional.
Here, angle G is an acute angle less than 45°, while corresponding angle J is an acute angle greater than 45°. These corresponding angles in the similarity statement are not congruent, so the similarity statement is false.
__
Additional comment
Side ratios in ∆GHI are 3 : 6 : 3√5 = 1 : 2 : √5.
Side ratios in ∆JKL are 2 : 5 : √29.
For comparison purposes, we like to list them shortest to longest.
These ratios are different, so even if the order of the vertices were straightened out, the triangles still would not be similar. If the triangles had the same side length ratios, the vertex order for a proper similarity statement would be ∆GHI ~ ∆KLJ.

The quadrilateral ABCD is a parallelogram if pairs of consecutive angles are supplementary. Given the angle measures, prove that quadrilateral ABCD is a parallelogram by finding the value of x. ∠A = 120 − 2x ∠B = 70 + x ∠C = 105 − x2 ∠D = 40 + 4x
The value of x from the parallelogram ABCD is 10.
What is parallelogram?A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent.
Given that, ∠A=120-2x, ∠B=70+x, ∠C=105-x² and ∠D=40+4x.
The quadrilateral ABCD is a parallelogram if pairs of consecutive angles are supplementary.
Here, ∠A and ∠D are consecutive angles
Now, 120-2x+40+4x=180
⇒ 160+2x=180
⇒ 2x=20
⇒ x=10
So, ∠A=120-2x=100, ∠B=70+x=80, ∠C=160-6x=100 and ∠D=40+4x=80
Therefore, the value of x is 10.

This season, the probability that the Yankees will win a game a is 0.53 and the
probability that the Yankees will

and score 5 or more runs is 0.42. What is the
probability that the Yankees will lose when they score 5 or more runs? Round
your answer to the nearest thousandth.
The probability that the Yankees will lose when they score 5 or more runs is equal to 0.2766.
What is Conditional Probability?
Conditional probability, or P(A/B), denotes the likelihood of event A that is dependent on event B.The chance of an event occurring given that another event has already occurred (via assumption, supposition, assertion, or evidence) is known as conditional probability in the field of probability theory.This particular approach assumes that event B occurs in some way related to event A. A conditional probability analysis with respect to event B in this scenario can be performed.The conditional probability formula is given as, [tex]P(M/N)=\frac{P(M\cap N)}{P(N)}[/tex]From the question, we know that the probability that the Yankees will win a game is 0.53.
[tex]\implies P(W)=0.53[/tex]
Also, then the probability that the Yankees will lose a game is given as,
[tex]P(L)=1-P(W)\\\implies P(L)=1-0.53\\\implies P(L)=0.47[/tex]
It is also given that, the probability that the Yankees will score 5 or more runs is 0.48.
[tex]\implies P(A)=0.48[/tex] -----(1)
So, the probability that the Yankees will score less than 5 runs is,
[tex]P(S)=1-P(A)\\\implies P(S)=1-0.5\\\implies P(S)=0.5[/tex]------(2)
We also know the probability that the Yankees will win and score 5 or more runs is 0.42.
[tex]\implies P(B)=0.42[/tex]
Also, then the probability that the Yankees will lose or score less than 5 runs is given as,
[tex]P(C)=1-P(B)\\\implies P(C)=1-0.42\\\implies P(C)=0.58[/tex]
Next, the probability that the Yankees will lose and score less than 5 runs is,
[tex]P(D)=0.42+0.5-0.58\\\implies P(D)=0.34[/tex]
Now, the required probability is the probability that the Yankees will lose and score 5 or more runs.
It can be calculated using the conditional probability formula, [tex]P(M/N)=\frac{P(M\cap N)}{P(N)}[/tex]
So, the required probability that the Yankees will lose and score 5 or more runs is given as,
P(they score 5 or more runs / probability that they lose game) = P(they lose and score 5 or more runs) / P(they lose the game)
[tex]\implies P(E)=\frac{0.47-0.38}{0.47} \\\implies P(E)=0.2766[/tex]
Therefore, the probability that the Yankees will lose when they score 5 or more runs is equal to 0.2766.

Determine a series of transformations that would map polygon ABCD onto poly
A'B'C'D'?
The polygon ABCD is transformed 4 units to the left after being reflected across the x-axis.
How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
Reflect the polygon ABCD across the x-axis as;
A(x, y) → A'(x, -y) (x, -y) (x, -y)
According to this rule, A's coordinates are
A(1, -5) → A'(1, 5) (1, 5) (1, 5)
ABCD is shifted 4 units further to the left.
Now apply to the translation:
A"(x - 4, y) = A'(x, y) (x - 4, y)
A'(1, 5) → A"(1 - 4, 5) (1 - 4, 5) (1 - 4, 5)
→ A"(-3, 5) (-3, 5) (-3, 5)
Thus Polygon ABCD will eventually overlap Polygon A'B'C'D' through a series of transformations.

A graph of the two (2) points (-0.5, 0) and (9, 0) that represent the distance which this object would travel in different amounts of time at that rate is shown in the image attached below.
How to write a linear function for the distance and time?Mathematically, a linear function is sometimes referred to as the slope-intercept form of a straight line and it can be modeled (represented) by this mathematical expression;
d = mt + b
Where:
d represents the distance.t represents the rate of change (slope).b represents the y-intercept.Therefore, the required linear function that relates the distance (d) and speed (s) at time (t) seconds is given by this mathematical expression;
d(t) = 18t + 9
For instance when time (t) = -0.5 seconds, the distance traveled by this object placed on a conveyor belt is given by;
d(t) = 18t + 9
d(-0.5) = 18(-0.5) + 9
d(-0.5) = -9 + 9

I AM ON A TEST HELP WHAT IS THE MAXIMUM OR MINIMUM VALUE AND WHAT ARE THE COORDINATES OF THE VERTEX y=2x^2+12x+5
The parabola's vertex is (-3/2, -22). Because this is the lowest point on the parabola, the function's minimum value is -22.
To determine the maximum or minimum value of the quadratic function y = 2x² + 12x + 5, you need to find the vertex of the parabola formed by this function.
To find the vertex of the parabola, you can use the formula x = -b / (2a), where x is the x-coordinate of the vertex, a is the coefficient of the x² term, and b is the coefficient of the x term.
In this case, the coefficient of the x² term is 2, and the coefficient of the x term is 12. Therefore, the x-coordinate of the vertex is x = -12 / (2×2) = -6 / 4 = -3/2.
To find the y-coordinate of the vertex, you can substitute the x-coordinate back into the original equation:
y = 2(-3/2)² + 12(-3/2) + 5 = 2(-9/4) + (-18) + 5 = -9 + (-18) + 5 = -22.
Therefore, the vertex of the parabola is (-3/2, -22). This is the lowest point on the parabola, so the minimum value of the function is -22.

Principal: $225, Interest Rate: 6%, Time: 2 years.
What is simple interest? I know it is something related to PxRxT or something like that.
Answer:
$27
Step-by-step explanation:
Simple interest is a way of calculating the interest charge on a loan or investment. It is calculated by multiplying the principal amount by the interest rate and the time period. In your example, the simple interest calculation would be $225 * 6% * 2 years = $27.
Answer:
Simple interest is a type of interest that is calculated only on the principal amount of a loan or investment, without taking into account any additional interest that has been earned on the principal. To calculate simple interest, you multiply the principal amount by the interest rate and the length of time the interest is being applied. For example, if you have a principal of $225, an interest rate of 6%, and a time of 2 years, the simple interest would be calculated as follows:
$225 x 6% x 2 years = $27.
In this case, the simple interest on the $225 principal would be $27. This means that after 2 years, you would owe $252 in total, including the original principal and the interest that has been earned on it. Simple interest is typically used for short-term loans or investments, where the interest is paid or earned at regular intervals, such as monthly or annually.
