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.

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

Plot two points that represent the distance an object would travel in different amounts of time at that rate.
Select two points on the coordinate grid. A line will connect the points.
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

How far does a wheel travel in 4 rotations with a radius of 36 inches?
Round to the nearest hundredths
The wheel will travel 904.32 inch when it take 4 rotation
How do you calculate distance using radius and revolutions?
Hint: To calculate the wheel's circumference, use the formula 2πr, where r is the radius and π=3.14 , to first determine the distance covered in one revolution. To determine the distance traveled, multiply the distance covered in one revolution by 200. In the end, multiply it by 100 to get the distance in meters.
In mathematics, what is the circumference?
The distance between the center of the sphere and any plane passing through it is known as the circumference. Any large circle that passes through a point known as a pole is called a meridian.
The circle's circumference must be known in order to compute the distance covered during one rotation. C=2πr is the formula for the circumference.
The radius, designated as r, is 36 inches. As a result, C=2π36 = 72π. The distance covered in one rotation is 226.08 inches because (pi) =3.14159, C=226.08 inches. So when we rotate this 4 times the it travels 226.08 * 4 = 904.32 inch

The value of slope for line equation 1 is -5/2. The value of slope for line equation 2 is 5/3.
What is slope?A line's steepness may be determined by looking at its slope. Slope is computed mathematically as "rise over run" (change in y divided by change in x). The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b. M represents the line's slope. B is the b in the location where the y-intercept is located (0, b). For instance, the slope and y-intercept of the equation y = 3x - 7 are 3 and 0, respectively.

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.

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.

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.
