How do you find a prime number multiples?
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A prime number can only be divided evenly by 1 and itself.
To find the multiples of a prime number, you can use the following steps:
Start with the prime number itself. This is the first multiple of the prime number.Multiply the prime number by 2. This will give you the second multiple of the prime number.Multiply the prime number by 3. This will give you the third multiple of the prime number.Repeat step 3 for larger and larger integers (4,5,6,7,8....) until you reach the desired number of multiples.For example, if the prime number is 5, the multiples of 5 are 5, 10, 15, 20, 25, and so on.
It's important to note that a prime number only has two divisors: 1 and itself. This means that a multiple of a prime number will never be a prime number.

which of the following is not the solution of 3x+6y=12?A) (-4,4) B) (0,2)C) (8,-2)D) (3,1)
(3,1) is not the solution of the equation 3x + 6y = 12. So the option D is correct.
In the given question, we have to check which of the following is not the solution of 3x+6y=12.
To check which is not the solution of the given equation, we put the value of x and y from the given point. If for any point the condition is true then that point is the solution of the given equation. If that point doesn't satisfy the condition then that point is not the solution of the given equation.
The given equation is 3x+6y=12.
Firstly we check for the point (-4,4), where x = -4, y = 4
3(-4) + 6(4) = 12
-12 + 24 = 12
12 = 12(True)
Now we check for the point (0,2), where x = 0, y = 2
3(0) + 6(2) = 12
0 + 12 = 12
12 = 12(True)
Now we check for the point (8,-2), where x = 8, y = -2
3(8) + 6(-2) = 12
24 - 12 = 12
12 = 12(True)
Now we check for the point (3,1), where x = 3, y = 1
3(3) + 6(1) = 12
9 + 6 = 12
15 = 12(False)
Hence, (3,1) is not the solution of the equation 3x + 6y = 12. So the option D is correct.

Is it possible to have a triangle with sides 2cm 2cm and 5cm justify your answer?
Answer:
No, it is not possible to have a triangle with sides of 2cm, 2cm, and 5cm. This is because a triangle's sides must adhere to the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In this case, 2cm + 2cm (4cm) is not greater than 5cm, so it is not possible to form a triangle with these side lengths.

Mendel's law of segregation states that gametes only carry one allele for each gene. How much genetic information does a gamete carry, compared to a body cell?.
Gametes carry half the genetic information of an individual, one ploidy of each type, and are created through meiosis, in which a germ cell undergoes two fissions, resulting in the production of four gametes.
About Mendel's Law IMendel's Law I has another name, namely the Law of Segregation. In the Law of Segregation it states that "In the formation of gametes (sex cells) in the two genes which are partners, will be separated in two daughter cells". Mendel's Law I or the Law of Segregation applies to monohybrid crosses, aka crosses with one different trait.
Mendel's First Law also states that two alleles (gene variants) that regulate certain traits will separate in two different gametes (sex cells). Mendel's Law I includes several things, namely:
Alleles (gene variations) for inherited trait variations. For example: the colors of two different flowers, called alleles, will occupy the locus that corresponds to the homologous pair. Two alleles for a character will separate when gametes (sex cells) are produced. Example: the result of a cross containing one allele of the parent flower color (purple or white) Each character in each organism will inherit two alleles, each of which comes from the parent. Example: the result of a cross that is likely to produce 1 white allele and 1 purple allele. If there are two different alleles, one of them will be dominant, while the other will be recessive. Example: there is a marriage of purple flowers with white flowers, it will produce purple offspring.Learn more about Mendel's law https://brainly.com/question/23067535.

Use method of reduction of order to find a second solution y2(x) of the homogeneuos equation and a particular solution of the given nonhomogeneous equation:

The homogeneous equation and a particular solution of the given nonhomogeneous equation is [tex]& y=c_1 e^{-2 x}+c_2 e^{2 x}-\frac{1}{2}[/tex].
The given nonhomogeneous equation is y" - 4y = 2
We are given [tex]$y_1=e^{-2 x}$[/tex]
Let [tex]$y_2=u y_1$[/tex]
A linear differential equation is homogeneous if it is a homogeneous linear equation in the unknown function and its derivatives.Non-homogeneous differential equations are simply differential equations that do not satisfy the conditions for homogeneous equations. In the past, we’ve learned that homogeneous equations are equations that have zero on the right-hand side of the equation.
The two most common methods when finding the particular solution of a non-homogeneous differential equation are:
The method of undetermined coefficients. The method of variation of parameters.[tex]$$\begin{aligned}& y_2=u e^{-2 x} \\& y_2^{\prime}=u^{\prime} e^{-2 x}-2 u e^{-2 x} \\& y_2^{\prime \prime}=u^{\prime \prime} e^{-2 x}-2 u^{\prime} e^{-2 x}-2 u^{\prime} e^{-2 x}+4 u e^{-2 x} \\& y_2^{\prime \prime}=u^{\prime \prime} e^{-2 x}-4 u^{\prime} e^{-2 x}+4 u e^{-2 x}\end{aligned}$$[/tex]
Substitute in [tex]$y^{\prime \prime}-4 y=0$[/tex], we get
[tex]$$\begin{aligned}& u^{\prime \prime} e^{-2 x}-4 u^{\prime} e^{-2 x}+4 u e^{-2 x}-4 u e^{-2 x}=0 \\& u^{\prime \prime} e^{-2 x}-4 u^{\prime} e^{-2 x}=0 \\& e^{-2 x}\left(u^{\prime \prime}-4 u^{\prime}\right)=0 \\& u^{\prime \prime}-4 u^{\prime}=0 \\& u^{\prime \prime}=4 u^{\prime}\end{aligned}$$[/tex]
Substitute [tex]$$u^{\prime}=v$ and $u^{\prime \prime}=v^{\prime}$[/tex], we get
[tex]$$\begin{aligned}& v^{\prime}=4 v \\& \frac{d v}{d x}=4 v \\& \frac{1}{v} d v=4 d x\end{aligned}$$[/tex]
Integrate both sides, we get
[tex]$u=\frac{1}{4} C_1 e^{4 x}+C_2$$[/tex]
put in [tex]$y_2=u y_1$[/tex]
[tex]$$y_2=\left(\frac{1}{4} C_1 e^{4 x}+C_2\right) e^{-2 x}$$[/tex]
Choose [tex]$$C_1=4$ and $C_2=0$[/tex], we get
[tex]$$y_2=e^{2 x}$$[/tex]
[tex]$$\begin{aligned}& y_c=c_1 y_1+c_2 y_2 \\& y_c=c_1 e^{-2 x}+c_2 e^{2 x}\end{aligned}$$[/tex]
Particular Solution
[tex]$$\begin{aligned}& y_y=A \\& y_y{ }^{\prime}=0 \\& y_y{ }^{\prime \prime}=0\end{aligned}$$[/tex]
Substitute in [tex]$y^{\prime \prime}-4 y=2$[/tex], we get
[tex]$$\begin{aligned}& 0-4 A=2 \\& -4 A=2 \\& A=-\frac{1}{2} \\& \therefore y_y=-\frac{1}{2}\end{aligned}$$[/tex]
General Solution

Two angle measures of this triangle are 60°. Which type of triangle is it?
A.
obtuse
B.
scalene
C.
equilateral
D.
right
Answer: C. Equilateral
Step-by-step explanation:
Answer: option C is correct. two angle measures of an equilateral triangle is 60°
Step-by-step explanation: All the sides of an equilateral triangle are of equal lengths—each interior angle of this triangle measures 60°.
One angle of a triangle measures 70°. The other two angles are in a ratio of 4:7. What are the measures of those two angles?
The measure of the other two angles are 88 degrees and 22 degrees.
Let's call the two unknown angles x and y. Since the sum of all angles in a triangle is 180 degrees, we have:
x + y + 70 = 180
We also know that the ratio of the two angles is 4:7. We can set up a proportion to express this relationship:
x/y = 4/7
We can cross-multiply to get:
7x = 4y
We can substitute this equation into the first equation to eliminate one of the variables.
7x + y + 70 = 180
Now we have:
7x + y = 110
We can use the second equation to eliminate x:
7(4y/7) + y = 110
4y + y = 110
5y = 110
y = 22
Now that we know one of the angles is 22 we can substitute it back in the first equation
x+22+70 = 180
x = 88
Therefore, the measures of the other two angles are 88 and 22 degrees

Function or not a function?
In a dividing competition, scores range from 0 to 10. When three judges, the number of points awarded is calculated by multiplying the sum of the scores by the degree of difficulty. Your opponent earns 40.8 points on a dive. You perform a dive with a degree of difficulty of 2.4. Two of your scores are shown. What scores from the third judge will give you more points than your opponent?
Answer:
1.5 or greater than 1.5
Step-by-step explanation:
First, we need to determine the total score of your opponent's dive:
40.8 points / 2.4 (degree of difficulty) = 17 (total score)
Now, we know that your total score needs to be greater than 17, and the scores awarded by the three judges are added together.
To calculate the scores from the third judge, we can use the following equation:
(Total score) - (score from judge 1) - (score from judge 2) = (score from judge 3)
Let's assume that you received scores of 8 and 7.5 from the first two judges.
We can plug in the values into the equation:
(Total score) - (8) - (7.5) = (score from judge 3)
We know that your total score needs to be greater than 17, so we have to find the score from the third judge, that when added to the scores 8 and 7.5, gives a total score greater than 17
17 - 8 - 7.5 = 1.5
The score from the third judge should be 1.5 or greater than 1.5 in order to give you more points than your opponent.

Answer:
"A) 12n + 14m + 4" would be the standard form.
Step-by-step explanation:
the expression written correctly in standard form would be "A) 12n + 14m + 4"
10m + 3(n + 8) + 4(m - 5) + 9n you need to first clear the parenthesis by applying distributive property:
10m + 3(n + 8) + 4(m - 5) + 9n = 10m + 3n + 24 + 4m - 20 + 9n
After that you combine like terms
= 10m + 4m + 3n + 9n + 24 - 20 = 14m + 12n + 4
"A) 12n + 14m + 4" would be the standard form.
