rotation in the direction of 90°: (x,y) becomes (y,-x) rotation of (x,y) at 90 degrees counterclockwise results in (-y,x) Rotating (x, y) 180 degrees both clockwise and counterclockwise results in (-x,-y) Rotating (x,y) in a 270° clockwise direction (-y,x).Upon 360-degree rotation, a point with the coordinates (x, y) is produced.
How is rotation calculated?
The number of central angles multiplied by the size of each central angle gives the angle of rotation between the two points or vertices: rotational angle =m = m
The term "order of rotation" refers to how many times a figure appears the same after a full 360-degree rotation. The angle of rotation can also be used to compute the order of rotation. A figure's rotational order can be determined using the angle of rotation (360°). A line segment rotates at a 180° angle.
Precession, nutation, and intrinsic rotation are the names of these rotations.

Define integer give me an example of a number that is an integer and a number that is not an integer
Step-by-step explanation:
An integer (pronounced IN-tuh-jer) is a whole number (not a fractional number) that can be positive, negative, or zero. Examples of integers are: -5, 1, 5, 8, 97, and 3,043. Examples of numbers that are not integers are: -1.43, 1 3/4, 3.14, . 09, and 5,643.1.
Two sides of an isosceles triangle have lengths of 3 and 6. What is the length of the third side?A. 6B. 9C. 3D. 5
It is given that the triangle is isosceles and the sides are 3 and 6.
Since the triangle is isosceles so third side will be either 3 or 6 .
If third side is 3 then we have
[tex]3+3=6[/tex]which is a contradiction to the fact that sum of two sides of a triangle is greater than the third side.
So the third side will be 6.
Hence the correct option is (A).

Find the value of the test statistic z.The claim is that the proportion of peas with yellow pods is equal to 0.25 (or 25%). The sample statistics from one experiment include 430 peas with 126 of them having yellow pods.
You have to calculate the z-value or value of the test statistic z, for the proportion of yellow pods. The form of the z-statistic used to study the population proportion is:
[tex]Z=\frac{\hat{p}-p}{\sqrt[]{\frac{p(1-p)}{n}}}\approx N(0,1)[/tex]The population proportion of the yellow pods is p=0.25.
From a sample of 430 peas, 126 of them had yellow pods, using this information you have to calculate the sample proportion p-hat (^p)
The sample proportion is equal to the quotient between the number of successful outcomes "x" (number of yellow pods) and the total number of outcomes "n" (number of peas sampled)
[tex]\begin{gathered} \hat{p}=\frac{x}{n} \\ \hat{p}=\frac{126}{430} \\ \hat{p}=0.29 \end{gathered}[/tex]Once determined the sample proportion, you can calculate the z-value as follows:
[tex]\begin{gathered} Z=\frac{0.29-0.25}{\sqrt[]{\frac{0.25(1-0.25)}{430}}} \\ Z=\frac{0.04}{\sqrt[]{\frac{0.25\cdot0.75}{430}}} \\ Z=\frac{0.04}{\sqrt[]{\frac{0.1875}{430}}} \\ Z=1.915\approx1.92 \end{gathered}[/tex]The value of the test statistic is 1.92.
*-*-*-*-*
The standard deviation of the distribution of the sample proportion:
To simplify the calculations you can calculate the standard deviation separately, the formula for this measure is the denominator of the formula of the Z-statistic:
[tex]\sigma=\sqrt[]{\frac{p(1-p)}{n}}[/tex]Using p=0.25
[tex]\begin{gathered} \sigma=\sqrt[]{\frac{0.25(1-0.27)}{430}} \\ \sigma=\sqrt[]{\frac{0.25\cdot0.75}{430}} \\ \sigma=\sqrt[]{\frac{0.1875}{430}} \\ \sigma=\sqrt[]{\frac{3}{6880}} \\ \sigma=0.0208 \end{gathered}[/tex]Then you can replace the result in the denominator of the formula to determine the Z-value:
[tex]\begin{gathered} Z=\frac{\hat{p}-p}{\sqrt[]{\frac{p(1-p)}{n}}} \\ Z=\frac{0.29-0.25}{0.0208} \\ Z=\frac{0.04}{0.0208}\approx1.92 \end{gathered}[/tex]482 + 51.8 =

In order to divide a mixed number by a fraction we have to take into account:
- It is easier to convert the mixed number into an equivalent fraction.
- Dividing by a fraction is equivalent to multiplying by the reciprocal of that fraction.
In this case, we have to divide the number 2 1/4 by 1/2.
We start by converting it to a fraction:
[tex]2+\frac{1}{4}=\frac{2\cdot4+1}{4}=\frac{8+1}{4}=\frac{9}{4}[/tex]Then, we have to divide it by 1/2. As we state before, this is the same as multiply by the reciprocal: 2/1, so we have:
[tex]\frac{\frac{9}{4}}{\frac{1}{2}}=\frac{9}{4}\cdot\frac{2}{1}=\frac{18}{4}=\frac{16+2}{4}=\frac{16}{4}+\frac{2}{4}=4+\frac{1}{2}[/tex]Answer: 4 1/2
find the probability that a family with 12 children will have at least one boy 
The probability that a family with 12 children will have at least one boy is 99.97%.
What is probability?The study of random events is the focus of the mathematical field known as probability theory. A random event's outcome can take any of a number of possible forms; it cannot be predicted before it happens. The outcome as it occurs is thought to have been determined by chance.
In everyday language, the word "probability" can mean a number of things. In order to develop and apply the mathematical theory of probability, two of these are particularly crucial. One is the interpretation of probabilities as relative frequencies; simple games involving coins, cards, dice, and roulette wheels serve as examples for this.
Assuming that the outcome of child born as a bopy or girl is 50% then each boy has a probability of 1/2
The odds of having all girls is = 1/2¹² = 1/4096 ≈ 0.000244
The odds of have at least 1 boy = 1 - 1/4096
= 0.999756
Converting to percentage = 99.97%
Thus, the probability that a family with 12 children will have at least one boy is 99.97%.

It is stated in the problem that ΔGEO is congruent with ΔFUN. On the first triangle, the measurement of angle E and angle G is given but the measurement of angle O is not given. Using the congruence relation of the two triangles, it is true that
[tex]m\angle O\cong m\angle N[/tex]The measurement of angle N is provided in the problem, which is equal to 40 degrees. Hence, we can say that angle O has also an angle measurement of 40 degrees base on the statement above.
The sum of the interior angles of the triangle is equal to 180 degrees. This means that if we add up the interior angles of the triangle GEO, we have the following equation
[tex]m\angle G+m\angle E+m\angle O=180[/tex]Substitute the measurement of each angle on the equation above and compute, we get
[tex]\begin{gathered} 60+4x+40=180 \\ 4x+100=180 \\ 4x=180-100 \\ \frac{4x}{4}=\frac{80}{4} \\ x=20 \end{gathered}[/tex]Therefore, the value of x is equal to 20 degrees.

Determine which set of side measurements could be used to form a triangle.
12, 23, 7
10, 7, 2
8, 3, 11
5, 11, 8
Answer:
Among the given, the set of side measurements (5, 11, 8) could be used to form a triangle.
Step-by-step explanation:
As we know,
For forming a triangle, "The sum of the length of any two sides of a triangle is greater than the length of the third side."
The side opposite the largest angle of a triangle is the largest side. Any exterior angle of the triangle is equal to the sum of its interior opposite angles.
Now taking the value given in the option:
We have the first set of values: 12, 23, 7
As here, let us assume that, a = 12, b = 23, c = 7
So, for the formation of triangle a + b > c
So, 12 + 7 = 19 < 23
Hence, this set of values can't form a triangle.
We have the second set of values: 10, 7, 2
As here, let us assume that, a = 7, b = 2, c = 10
So, for the formation of triangle a + b > c
So, 7 + 2 = 9 < 10
Hence, this set of values can't form a triangle.
We have the third set of values: 8, 3, 11
As here, let us assume that, a = 8, b = 3, c = 11
So, for the formation of triangle a + b > c
So, 8 + 3 = 11 < 11
Hence, this set of values can't form a triangle.
We have the fourth set of values: 5, 11, 8
As here, let us assume that, a = 5, b = 8, c = 11
So, for the formation of triangle a + b > c
So, 5 + 8 = 13 > 11
Hence, this set of values can form a triangle.
