Answer:
20: Pattern 8.
21: n * n = 64
Step-by-step explanation:
8*8=64, so assuming that n is the missing variable, if we use 8 in place of n, we have 64, the "equals (=)" value will always change depending on n's value. So assuming n is equal to 8, 8*8=64

Find the equation of a line that passes through the points (-1,-3) and (1,-5).
Answers
The equation of the line is (y + x = 0).
What exactly do you understand by slope?The slope of a line indicates its steepness in addition to its direction.
A line's slope is defined as the change in y coordinate in regards to a change in x coordinate.The total increase in y coordinates is Δy, while it is x in Δx coordinates.As a result, the y coordinate shift in relation to the x coordinate shift could be written as,m = Δy/Δx
where, m is the slope
And, tan θ = Δy/Δx
The above tan is also known as the line's slope.
The slope of a line can also be calculated just using two straight line points. The slope of line formula could then be used with two point coordinates.
Now, in response to the question;
P₁ = (x₁, y₁)
P₂ = (x₂, y₂)
Then slope will be;
Slope = m = tan θ = (y₂ - y₁)/(x₂ - x₁)
Consider the values given in the question;
(x₁, y₁) = (-1,-3) and,
(x₂, y₂) = (1,-5).
Put the values in the formula of the slope;
Slope = m = (-5 + 3)/(1 + 1)
m = -2/2
m = -1
Thus, the slope of the line is -4.
Now, the formula for finding the equation of line using the two points system.
(y - y₁) = m(x - x₁)
(y + 3) = (-1)(x + 1)
y + 3 = -x - 1
y + x + 4 = 0.
Therefore, the equation of the line using two point system is calculated as (y + x = 0).

The correct option is C. (0, 1, 2); function. The domain of the function is (0, 1, 2).
What is defined as the function and its domain?Functions are used to allocate outputs to inputs. A function's domain is the set of possible inputs to the function. The domain of f(x)=x² is all real numbers, for example, and the domain of g(x)=1/x has been all real numbers except x=0. We can also characterize special functions with more limited domains.For the given question;
The relation is;
(x, y) = {(0, 0), (1, 1), (2, 0)}
Take out the values for x.
x = {0, 1, 2}
The above set indicates that the x-values begin at 0 and end at 2.
As a result, the domain is {0, 1, 2}.
To be a function, all of the relation's y-values must refer to different x-values.
Since all y-values possess unique x values, we can say that the provided relation is a function.
Therefore, the given relation defines a function with domain of {0, 1, 2}.

According to the given data the non - degenerated closed interval in r is calculated as [tex]\int\limits^t_s[/tex]f(t) - f(s).
What is the degenerated interval?Any set that only contains one real number is known as a degenerate interval (i.e., an interval of the form [a,a]). an interval is measured in terms of numbers. An interval is any integer that falls between two specific numbers. This range encompasses all real numbers between those two. Real numbers can be any number anyone can think of. A degenerate interval is any set that contains only one real number (i.e., an interval of the form [a, a]). The empty set is included in this definition by some authors. A suitable interval is one that is either empty or degenerate and has an infinite number of elements.
According to the given data:f(x[tex]_r[/tex]) - f(x[tex]_r[/tex]₋₁) = F' (e[tex]_r[/tex])(x[tex]_r[/tex] - x[tex]_r[/tex]₋₁)

Answers
The slope of the line represented by the equation -5x + 2y = 10 is slope = -5/2 and y intercept= -5
In order to answer the question, we must first simplify the given linear equation so that it may be expressed as a regular linear equation with slope and intercept. A linear equation's slope intercept form is y=mx+b , where "m" denotes the line's slope and "b" its y-intercept. The value of y = 0 must then be entered for the x-intercept, and the value of "x" must then be determined. We will obtain all necessary values in this manner.
By slope-intercept form equation of the line:
y=mx+b
The advantage of the equation in this form is that m and b can be derived 'easily'
Rearrange -5x-2y = 10 in this form.
-2y=5x+10
y=-5/2x+-10/2

Translate △XYZ 9 units to the right and then 11 units down to get △JLK.
We need to map △XYZ to △JLK.
From the figure, △XYZ is in the 2nd quadrant and △JLK is in the 4th quadrant.
Also it is clear that side XY is mapped to JK, YZ to KL and XZ to JL.
To find the distance translated to the right we need to find the distance between the x- coordinates of the corresponding points of the two triangles as they are congruent.
Consider Y and K. The x- distance between Y and K = 6 - - 3 = 9 units.
So first 9 units translation to right.
Similarly, To find the translation downwards, we need to find the distance between the y-coordinates of Y and K.
y-Distance between Y and K = 1- -10 = 11 units.
So next 11 units translation to down.
This will give the △JLK from △XYZ .

Answers
The length of the arc of the partial circle is 18.84 units.
As per the question statement, we are supposed to find out the length of the arc of the partial circle as given in the figure provided.
Before solving this question, we need to know the formula for calculating the arc length of the circle i.e.,
Arc Length = [tex]2\pi r(\frac{\alpha }{360} )[/tex]
where [tex]\alpha[/tex] is the angle provided between the arc end in degrees
[tex]r[/tex] is the radius of the given circle in given units and
[tex]\pi =3.14[/tex]
In the given circle, the angle subtended by the arc is complete angle minus 90 degrees i.e.,
[tex]\alpha =360 - 90 = 270 degrees[/tex]
radius [tex]r[/tex] = 4 units (given)
Therefore Arc Length = [tex]2\pi r(\frac{\alpha }{360} )[/tex]
[tex]= 2*3.14*4*(\frac{270}{360})\\ =25.12(0.75)\\=18.84 units[/tex]

Answers
Slack of a3 is 6 weeks.
What is slack?
Slack variables are variables that are introduced to an inequality constraint in an optimization problem to change it into an equality. An inequality constraint is replaced by an equality requirement and a non-negativity constraint on the slack variable when a slack variable is introduced. In particular, slack variables are employed in linear programming. The slack variable, like the other variables in the augmented constraints, can only have positive or zero values because of the simplex method. A constraint is binding at a certain candidate solution if its associated slack variable is zero because it limits the modifications that can occur after that.
