O R.1800 or
OrRc¹.180°
Answers
Option-4 is correct, r m 0 Rc180° because the figure A'B'C'D'E' is obtained by rotating it by 180 degrees.
Given that,
We have to find which rule best explains the arrangement of transformations that converts figure ABCDE into figure A"B"C"D"E.
The diagram is given in the image.
Figure ABCDE is changed to Figure A"B"C"D"E in the provided figure.
The reflected image of a figure travelling along a line is situated at the same angle from the line as the original figure.
To create the figure A'B'C'D'E', the figure ABCDE must first be mirrored through the line m. The x and y coordinates of a figure change position and the y sign is inverted when it is rotated by 180 degrees.
The figure A'B'C'D'E' is obtained by rotating it by 180 degrees.
The final option, r m 0 Rc180°, is the correct one among all the others.
Therefore, Option-4 is correct, r m 0 Rc180° because the figure A'B'C'D'E' is obtained by rotating it by 180 degrees.

Answers
Applying the exterior angle theorem, the measure of the exterior angle to angle X is: B 112.55°.
How to Apply the Exterior Angle Theorem?In other to find the measure of the exterior angle to angle X, we have to recall the theorem known as the exterior angle theorem, which states that the measure of an exterior angle is equal to the two interior remote angles that are opposite to it.
In triangle XYZ, angle Y and Z are the remote interior angles. We are given the following:
Measure of angle Y = 38.25°
Measure of angle Z = 74.3°
Therefore:
The measure of the exterior angle to angle X = measure of angle Y + measure of angle Z
Substitute
The measure of the exterior angle to angle X = 38.25° + 74.3°
The measure of the exterior angle to angle X = 112.55°

Answer:
The sample mean = 1.8
Step-by-step explanation:
I just completed the test and this was the correct answer
The sample mean for the data is 1.8 if the first 10 people to check out books lived out of 20 population.
What are population and sample?It is defined as the group of data having the same entity which is related to some problems. The sample is a subset of the population, it is a part of the population.
We have:
Total number of population = 20
To calculate the sample mean:
Total number of samples N = 10
Sum of the sample values ∑x = 0.5+1.8+0.8+1.8+3.5+4.8+ 0.6+ 2+1.5+0.5
∑x = 17.8
Now the mean of the sample data = ∑x/N = 17.8/10 = 1.78 ≈ 1.8
Thus, the sample mean for the data is 1.8 if the first 10 people to check out books lived out of 20 population.

Find the negation of the following statements and then determine the truth value if the universe of discourse is the set of all integers. (a) ∀x(2x−1<0) (b) ∃x(x 2 =9)
Answers
(a) The negation of the statement "∀x(2x−1<0)" is "∃x(¬(2x−1<0))", which can be read as "There exists an integer x such that 2x−1 is not less than 0."
(b) The negation of the statement "∃x(x^2≠9)" is "∀x(¬(x^2≠9))", which can be read as "For all integers x, x^2 is equal to 9."
(a) The negation of the statement "∀x(2x−1<0)" is "∃x(¬(2x−1<0))", which can be read as "There exists an integer x such that 2x−1 is not less than 0."
To determine the truth value of this negated statement when the universe of discourse is the set of all integers, we need to find a counterexample that makes the statement false. In other words, we need to find an integer x for which 2x−1 is not less than 0. Solving the inequality 2x−1≥0, we get x≥1/2.
However, since the universe of discourse is the set of all integers, there is no integer x that satisfies this condition. Therefore, the negated statement is false.
(b) The negation of the statement "∃x(x^2≠9)" is "∀x(¬(x^2≠9))", which can be read as "For all integers x, x^2 is equal to 9."
To determine the truth value of this negated statement when the universe of discourse is the set of all integers, we need to check if all integers satisfy the condition that x^2 is equal to 9. By examining all possible integer values, we find that both x=3 and x=-3 satisfy this condition, as 3^2=9 and (-3)^2=9. Therefore, the statement is true for at least one integer, and thus, the negated statement is false.

Asx approaches negative infinity, for which of the following functions does f(x) approach positive infinity? Select all that apply. Select all that apply: f(x) =2x5 Ofx)9x +100 f(x)= 6x8 +9x6+32 f(x)=-8x3 + 11 f(x)=-10x +5x+ 26 f(x)=-x +8x4 + 248
Answers
Among the provided functions, the ones that approach positive infinity as x approaches negative infinity are:
- f(x) = 2x^5
- f(x) = 6x^8 + 9x^6 + 32
- f(x) = -x + 8x^4 + 248
To determine which functions approach positive infinity as x approaches negative infinity, we need to analyze the leading terms of the functions. The leading term dominates the behavior of the function as x becomes very large or very small.
Let's examine each function and identify their leading terms:
1. f(x) = 2x^5
The leading term is 2x^5, which has a positive coefficient and the highest power of x.
As x approaches negative infinity, this term becomes very large and positive, indicating that f(x) approaches positive infinity.
2. f(x) = 9x + 100
The leading term is 9x, which has a positive coefficient but a lower power of x compared to the constant term 100.
As x approaches negative infinity, the leading term becomes very large and negative, indicating that f(x) approaches negative infinity, not positive infinity.
3. f(x) = 6x^8 + 9x^6 + 32
The leading term is 6x^8, which has a positive coefficient and the highest power of x.
As x approaches negative infinity, this term becomes very large and positive, indicating that f(x) approaches positive infinity.
4. f(x) = -8x^3 + 11
The leading term is -8x^3, which has a negative coefficient and the highest power of x.
As x approaches negative infinity, this term becomes very large and negative, indicating that f(x) approaches negative infinity, not positive infinity.
5. f(x) = -10x + 5x + 26
Combining like terms, we have f(x) = -5x + 26.
The leading term is -5x, which has a negative coefficient but a lower power of x compared to the constant term 26.
As x approaches negative infinity, the leading term becomes very large and positive, indicating that f(x) approaches negative infinity, not positive infinity.
6. f(x) = -x + 8x^4 + 248
The leading term is 8x^4, which has a positive coefficient and the highest power of x.
As x approaches negative infinity, this term becomes very large and positive, indicating that f(x) approaches positive infinity.
Therefore, the correct choices are:
- f(x) = 2x^5
- f(x) = 6x^8 + 9x^6 + 32
- f(x) = -x + 8x^4 + 248

Is the outcome random if we know the possible values it can have?Randomness refers to the property of a process or system where the outcome is uncertain, unpredictable, and not predetermined. In a random process, we know the set of possible outcomes.
But we cannot determine which particular outcome will occur until it actually happens. For example, when flipping a fair coin, the possible outcomes are heads or tails.

Write the equation of the ellipse 36x² + 4y² + 216x − 16y + 196 = 0 in standard form.
Answers
The equation of the ellipse 36x² + 4y² + 216x - 16y + 196 = 0 can be written in standard form as ((x + 3)²)/16 + ((y - 1)²)/9 = 1.
To express the equation of the ellipse in standard form, we need to rewrite it in a specific format: ((x - h)²)/(a²) + ((y - k)²)/(b²) = 1, where (h, k) represents the center of the ellipse, and a and b represent the lengths of the semi-major and semi-minor axes, respectively.
To begin, we'll group the terms involving x and y, completing the squares to create perfect squares. Rearranging the terms, we have:
36x² + 4y² + 216x - 16y + 196 = 0
(36x² + 216x) + (4y² - 16y) + 196 = 0
36(x² + 6x) + 4(y² - 4y) + 196 = 0.
Next, we'll complete the squares within the parentheses:
36(x² + 6x + 9) + 4(y² - 4y + 4) + 196 = 36(9) + 4(4)
36(x + 3)² + 4(y - 2)² + 196 = 324 + 16
36(x + 3)² + 4(y - 2)² = 340
((x + 3)²)/16 + ((y - 2)²)/85 = 1.
The equation is now in standard form. The center of the ellipse is (-3, 2), the semi-major axis is 4, and the semi-minor axis is √85. Therefore, the equation of the ellipse in standard form is ((x + 3)²)/16 + ((y - 2)²)/85 = 1.

C. 3x • 2x2 + (–2) • 2x2 + 2x2 • 5 + (–2) • 5
Answers
The correct expansion of (3x – 2)(2\(x^2\) + 5) is 3x • 2\(x^2\) + 3x • 5 + (–2) • 2\(x^2\) + (–2) • 5. Thus, option A is the right answer to the given question.
To expand an expression of multiplication of two variables to two variables is done as follows:
1. We take the first term of the first expression which in this case is 3x
2. We multiply it by the first term of the second expression. In this case, we get 3x • 2\(x^2\).
3. Subsequently we multiply the first term with further terms and add them. In the given case, the expression we get is 3x • 2\(x^2\) + 3x • 5
4. Then we take the second term of the first expression and repeat the above steps and add it to the existing equation.
We get x • 2\(x^2\) + 3x • 5 + (–2) • 2\(x^2\) + (–2) • 5 as the answer.
