The reflection across the x-axis changes the y-coordinate to its opposite. Thus, K(1, −1) becomes K(1, 1), N(4, 0) doesn't change, and Q(4, −4) becomes Q(4, 4).
The question's task is a reflection across the x-axis. This change involves flipping the coordinates in the plane over the x-axis. For a given point with coordinates (x, y), its reflection will have coordinates (x, -y). Let's apply this rule to the points given:
K(1, −1) will become K(1, 1)
N(4, 0) will remain N(4, 0) because it lies on the x-axis
Q(4, −4) will become Q(4, 4)
So, the reflected coordinates are K(1, 1), N(4, 0), Q(4, 4).

A square napkin is folded in half on the diagonal and placed on the diameter of a round plate (see diagram below). If the folded napkin spans the plate and the plate has an 18-inch diameter, what is the area of the space on the plate that is NOT covered by the napkin? Leave your answer in terms of .
Answer:
[tex]A=81(\pi-1)\ in^2[/tex]
Step-by-step explanation:
step 1
Find the area of the plate
The area of a circle is given by the formula
[tex]A=\pi r^{2}[/tex]
we have
[tex]r=18/2=9\ in[/tex] ---> the radius is half the diameter
substitute
[tex]A=\pi (9)^{2}\\A=81\pi\ in^2[/tex]
step 2
Find the area of the square napkin folded (is a half of the area of the square napkin)
we know that
The diagonal of the square is the same that the diameter of the plate
Applying Pythagorean theorem
[tex]D^2=2b^2[/tex]
where
b is the length side of the square
we have
[tex]D=18\ in[/tex]
substitute
[tex]18^2=2b^2[/tex]
solve for b^2
[tex]b^2=162\ in^2[/tex] -----> is the area of the square
Divide by 2
[tex]162/2=81\ in^2[/tex]
step 3
Find the area of the space on the plate that is NOT covered by the napkin
we know that
The area of the space on the plate that is NOT covered by the napkin, is equal to subtract the area of the square napkin folded (is a half of the area of the square napkin) from the area of the plate
so
[tex]A=(81\pi-81)\ in^2[/tex]
simplify
[tex]A=81(\pi-1)\ in^2[/tex]

what is the slope of the line that passes through the points (2,4) and (6,12)
Answer:
12
Step-by-step explanation:
because yes
Answer: 2
Explanation: To solve this problem, it's important to understand that we don't need to graph the line but we can use our slope formula. One method you could use is the graphing method which requires you to plot the points but I will be showing you the slope formula.
[tex]m =\frac{ ^{y}2 - ^{y}1 }{x^{2} - x^{1} }[/tex]
We take our second y minus our first y
which in this case is 12 - 4
over our second x minus our first x
which in this case is 6 - 2.
So 12 - 4 over 6 - 2 simplifies to 8/4.
Notice that our slope can
be simplified one step further.
So 8/4 reduces to 2.
So the slope of the line that passes through these points is 2.

Solve for u in terms of r, s, and t.
t= –rsu
u=
Answer:
u = - [tex]\frac{t}{rs}[/tex]
Step-by-step explanation:
Given
t = - rsu ( multiply both sides by - 1 )
- t = rsu ( divide both sides by rs )
- [tex]\frac{t}{rs}[/tex] = u
To find u in terms of r, s, and t given the equation t = -rsu, divide both sides by -rs to get u = -t / (rs).
To solve for u in terms of r, s, and t using the given equation t = -rsu, we need to isolate u. We do this by dividing both sides of the equation by -rs, which gives us u = -t / (rs). This shows that u is inversely proportional to the product of r and s, and directly proportional to -t.
Find the midpoint m of AB
The midpoint m of line segment AB, with a length of 22 units, is located at 11. Assuming A and B are evenly spaced, the midpoint is found using the formula [tex]\( m = \frac{{A + B}}{2} \)[/tex].
To find the midpoint m of line segment AB, where AB has a length of 22 units, we use the midpoint formula: [tex]\( m = \frac{{A + B}}{2} \)[/tex].
Here, A and B are the coordinates of the endpoints of AB.
Since no specific coordinates are provided, let's assume A and B are equally spaced on the line.
If A = 0 and B = 22, the midpoint m would be [tex]\( \frac{{0 + 22}}{2} = 11 \)[/tex].
Therefore, the midpoint of AB is 11.
To find the midpoint of line segment AB, use the midpoint formula by averaging the x-coordinates and y-coordinates of the endpoints A and B.
Explanation:The midpoint of a line segment AB can be found by using the midpoint formula. The formula is:
(x1 + x2) / 2, (y1 + y2) / 2
where (x1, y1) and (x2, y2) are the coordinates of points A and B respectively.
Plug in the values for the coordinates of A and B, and calculate the midpoint coordinates.
The question asks to find the midpoint of a line segment AB. To find this midpoint, one would typically use the midpoint formula, which is derived from the average of the x-coordinates and y-coordinates of the endpoints of the segment. The question seems to be associated with a geometry or physics context, but the process to find the midpoint remains the same. It involves adding the x-coordinates of both endpoints and dividing by 2 to find the x-coordinate of the midpoint, and doing the same with the y-coordinates for the y-coordinate of the midpoint.

If f(1)=9 and f(n)=f(n-1)+2 then find the value of f(5)
Answer:
Step-by-step explanation:
hello :
f(n)=f(n-1)+2
means : f(n)-f(n-1)=2
this is the arithmetic seq when the common dif is d= 2 and the first term is : 9
the n-ieme term is : f(n) = f(1) +(n-1)d
f(n) =9+2(n-1)
f(n) = 2n+7
so : f(5) = 2(5)+7 = 17
Final answer:
The value of f(5) is determined by consecutively applying the given recursive relation, f(n) = f(n-1) + 2, starting from the initial condition f(1) = 9. After applying this process four times, we find that f(5) is 17.
Explanation:
f(1) = 9
f(n) = f(n-1) + 2
To find the value of f(5), we can use the recursive formula provided:
f(2) = f(1) + 2 = 9 + 2 = 11
f(3) = f(2) + 2 = 11 + 2 = 13
f(4) = f(3) + 2 = 13 + 2 = 15
f(5) = f(4) + 2 = 15 + 2 = 17

Which of the following is not a property for all parallelograms?
A. Opposite sides are parallel.
B. All sides have the same length.
C. Opposite angles are congruent.
D. The diagonals bisect each other.
Answer:
B. All sides have that same length, would be the correct answer.
Step-by-step explanation:
Answers A,C, and D are all properties for all parallelograms.
Option B, which states that all sides have the same length, is not a property for all parallelograms. It is only true for rhombuses, which are a special type of parallelogram.
Explanation:Among the options given, the one that is not a property for all parallelograms is:
B. All sides have the same length.This statement is not true for all parallelograms; it is a specific property of a subset of parallelograms known as rhombi (singular: rhombus), where all four sides are congruent. However, a general parallelogram only requires opposite sides to be of equal length, not all four sides. To clarify further:
Opposite sides are parallel - True for all parallelograms.Opposite angles are congruent - True for all parallelograms.The diagonals bisect each other - True for all parallelograms.The key distinction here is understanding that while rhombi share all the properties of parallelograms, not all parallelograms are rhombi.

How many solutions does -103x-6=-6x-103
Answer:
one solution
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
Since this is a linear system, there can be 1, 0, or infinite solutions. In order to determine this, we need to solve this equation.
First, isolate the variables to one side:
0 = 97x -97
97x = 97
x = 1.
Thus there is one solution.
If we had gotten a statement such as 1 = 1, there would have been infinite.
If we had gotten a statement such as 1 = 0, there would have been no solution.

If the domain is restricted to the portion of the graph with a positive slope, how are the domain and range of the function and
its inverse related?
Since the domain of the original function is limited to x 6, the range of the inverse function is y s6.
Since the domain of the original function is limited to x> 4. the range of the inverse function is ys 1.
Since the range of the original function is limited to y > 6, the domain of the inverse function is x 26
Since the range of the original function is limited to y 4, the domain of the inverse function is x 1.
Answer:
Since the range of the original function is limited to y 6, the domain of the inverse function is x ≥ 6.
Step-by-step explanation:
The answer is the statement Since the range of the original function is limited to y > 6, the domain of the inverse function is x ≥ 6.
What is the domain of an inverse function?The domain of the inverse of a relation is the same as the range of the original relation. In other words, the y-values of the relation are the x-values of the inverse.
What is a positive slope?The positive slope definition tells us that a line with a positive slope is one where the right side of the line is higher than the left side of the line.
So, by the definition given above, we see that
if the range of the original function is limited to y > 6, the domain of the inverse function is x >= 6.
