Answer:
12) y = 2x + 8
13) ( -4, 3)
14) y + 3 = 1(x + 2) ; y = x - 1
Step-by-step explanation:
12) ( -2, 4) and (1, 10)
m=(y2-y1)/(x2-x1)
m= (10-4)/(1+2)
m=6/3
m = 2
y - y1 = m(x - x1)
y - 4 = 2(x + 2)
y - 4 = 2x + 4
y = 2x + 8
13)
y - y1 = m(x - x1)
y - 3 = 2(x +4)
( -4, 3)
14) ( -2, -3) and (4, 3)
m=(y2-y1)/(x2-x1)
m=(3+3)/(4+2)
m=6/6
m=1
y - y1 = m(x - x1)
y + 3 = 1(x + 2)
y + 3 = x + 2
y = x - 1

Which of the following best describes the relationship between Angle a and angle b in the image below ( Choose all that apply)
Answers
You are correct in selecting "linear pairs" since they form a straight line.
The angles are also adjacent because they're next to each other like that. In fact, "linear pair" means "adjacent and supplementary".
The angles are not complementary because they don't add to 90 degrees. Instead, they add to 180 degrees so that's what makes them supplementary.
The angles are also not vertical angles. They would need to be opposite one another in an X configuration for this to happen. This means vertical angles cannot be adjacent, and vice versa.
2 Answers: Choice B and Choice CAngle a and angle b within the image are the linear pairs of angle within the image below.
What is the angle?It is a direction from which an individual observe something.
How to determine relationship between angles?From the figure we are able to find that angle a and angle b are the linear pair because these are formed when two lines intersect one another at one point. The angles are said to be linear if they're adjacent to every other after the intersection of the 2 lines. The sum of angles of a linear pair is often adequate to 180 degrees.
Hence the angle a and angle b are linear pairs.

how many solutions does 3 ( x + 2 ) =3x + 1 have
Answers
Answer:
There are 0 solutions
Answer:
Zero
Step-by-step explanation:
Let's solve the equation first.
For now, I will focus on the LHS and simplify that:
3(x + 2) = 3x + 1
3x + 6 = 3x + 1
Rearrange
3x - 3x = 1 - 6
Simplify
0x = -5
0 = -5 which isn't true
So 3(x + 2) = 3x + 1 has 0 solutions.

Find two unit vectors orthogonal to both (8, 7, 1) and (-1, 1, 0). (smaller i-value) (larger i-value)
Answers
Two unit vectors orthogonal to both (8, 7, 1) and (-1, 1, 0) are (-1, -1, 15)/sqrt(227) and (-1, -1, 15)/sqrt(227).
To find two unit vectors orthogonal (perpendicular) to both (8, 7, 1) and (-1, 1, 0), we can use the cross product of the two given vectors. The cross product of two vectors will yield a vector that is orthogonal to both of them.
Let's calculate the cross product:
(8, 7, 1) × (-1, 1, 0) = [(7 * 0) - (1 * 1), (1 * -1) - (0 * 8), (8 * 1) - (7 * -1)]
= [-1, -1, 15]
Now, to obtain unit vectors, we divide this vector by its magnitude:
Magnitude of [-1, -1, 15] = sqrt((-1)^2 + (-1)^2 + 15^2) = sqrt(1 + 1 + 225) = sqrt(227)
Unit vector 1: (-1, -1, 15) / sqrt(227)
Unit vector 2: (-1, -1, 15) / sqrt(227)
Both of these unit vectors are orthogonal to both (8, 7, 1) and (-1, 1, 0).

If x is an eigenvector of an n×n matrix A with eigenvalue λ, then 4x is also an eigenvector of A, and it is has the same eigenvalue λ. True False
Answers
True. 4x is a re-scaled version of x, which is itself an eigenvector of A with associated eigenvalue λ. Multiplying every element in vector x by positive scalar, say 4, does not affect the direction of vector x, and thus 4x is also an eigenvector of A, which is still associated with the same eigenvalue λ.
From eigenvector-eigenvalue relationship, the eigenvectors of A can be determined by solving the following system of equations: (A - λI)x = 0. Where I is n×n identity matrix to our n×n matrix A. For4x, this is equivalent to (A - λI)4x = 0. That is, (4(A-λI)x) = 0. Since (A-λI)x = 0, then 4(A-λI)x = 0. Hence, 4x is still an eigenvector of A associated with the same eigenvalue λ.
Therefore, rescaling an eigenvector does not change the eigenvalue associated with it. That being said, 4x is also an eigenvector of A, and the associated eigenvalue is λ.

What does it mean when you use a 0. 05 level of significance (alpha level) to evaluate statistical results
Answers
The significance level, also denoted as alpha or α, is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference.
What is significance level?In statistical hypothesis testing, a result has statistical significance when a result that is at least as "extreme" as the null hypothesis would be extremely rare if the null hypothesis were true. The significance level of an event (for example, a statistical test) is the likelihood that the event occurred by chance. We call an occurrence important if the level is relatively low, that is, the likelihood of occurring by chance is quite minimal. When the null hypothesis is true, the significance level is the chance of rejecting it. A significance level of 0.05, for example, represents a 5% chance of finding that a difference exists when there is none.

Find the particular solution of the differential equation y ‘ −y=9 given the initial condition y(0)=5. Solve your answer for y. Y=
Answers
To find the particular solution of the given differential equation y' - y = 9 with the initial condition y(0) = 5, we can use the method of integrating factors.
First, rearrange the equation to get y' - y = 9 as y' - y - 9 = 0.
Now, notice that the coefficient of y' is 1 and the coefficient of y is -1. To make the equation exact, we need to multiply both sides by an integrating factor. In this case, the integrating factor is e^(-x).
Multiply both sides of the equation by
e^(-x) to get e^(-x)y' - e^(-x)y - 9e^(-x) = 0.
Now, the left side of the equation can be rewritten as
(e^(-x)y)' - 9e^(-x) = 0.
Integrate both sides with respect to x to get
e^(-x)y - 9∫e^(-x)dx = C,
where C is the constant of integration.
Simplifying further, we have
e^(-x)y + 9e^(-x) = C.
Since we are given the initial condition y(0) = 5, we can substitute x = 0 and y = 5 into the equation to find the value of C.
Plugging in the values, we have
e^(0)(5) + 9e^(0) = C,
which gives us 5 + 9 = C. Thus, C = 14.
Substituting C = 14 back into the equation, we have e^(-x)y + 9e^(-x) = 14.
Now, solve this equation for y to find the particular solution.
Rearranging the equation, we have e^(-x)y = 14 - 9e^(-x).
Divide both sides by e^(-x) to get y = (14 - 9e^(-x))e ^x.
Simplifying further, we have y = 14e^x - 9.
Therefore, the particular solution of the given differential equation is y = 14e^x - 9.

To form a five-letter code with no repeated letters, we need to select 5 different letters from the available options.
How many different security codes are possible with a person's first and last initials and 4 digits? (b) How many ways can a five-letter code be formed without repeating any letters?The number of different security codes possible can be calculated by multiplying the number of options for each component.
Assuming 26 letters in the alphabet and 10 digits, the number of different security codes is 26 (options for the first initial) * 26 (options for the last initial) * 10 (options for each digit) * 10 (options for each digit) * 10 (options for each digit) * 10 (options for each digit). Resulting in a total of 26^2 * 10^4 = 676,000 different security codes.Assuming 26 letters in the alphabet, the number of ways to form such a code is given by the combination formula, which is C(26, 5) = 26! / (5! * (26-5)!) = 26! / (5! * 21!) = (26 * 25 * 24 * 23 * 22) / (5 * 4 * 3 * 2 * 1) = 65,780 ways.
