Parallelogram Property 4 The diagonals of a parallelogram bisect each other. Show Mel Given: Parallelogram CURE with diagonals bar (CR) and bar (UE) Prove bar (CR) and bar (UE) bisect each other. Proo
Therefore , the solution of the given problem of parallelograms comes out to be C and R are equally distanced from point N, the midpoint of UE and RN Equals NC.
How do parallelograms function?In Euclidean mathematics, a simple quadrilateral of two sets of equal distances is referred to as a parallelogram. In a specific kind of quadrilateral known as a parallelogram, both set of opposite sides are straight and equal. There are four types of parallelograms, 3 of which are each mutually exclusive. Rhombuses, parallelograms, squares, but also rectangles are the four distinct shapes.
Here,
We must demonstrate that OM = MR in order to establish that O is CR's middle.
=> CO / OU Equals RC / UE
This solution can be rearranged to account for RC:
=> RC Equals UE * (CO / OU)
But we also understand that OU = CO (since they are diagonals of the same parallelogram). Therefore:
=> RC = UE
This indicates that point M, the CR's centre, is equally spaced from C and U. Or put another way, OM Equals MU.
To demonstrate that O is also the midpoint of UE, we can use a similar argument.
Triangles CRU and EUC are comparable to one another (by AA resemblance), so we have:
=> UE/CR equals UC/CR
To solve for UE, rearrange this equation as follows:
=> UE = UC
As a result, C and R are equally distanced from point N, the midpoint of UE. That is to say, RN Equals NC.

which function would be produced by a horizontal stretch of the graph of y = √x followed by a felection in the x-axis
Answer:
\(y=- \sqrt{\dfrac{1}{2}x}\)
Step-by-step explanation:
Parent functions are the simplest form of a given family of functions.
Transformations of graphs (functions) is the process by which a function is moved or resized to produce a variation of the original (parent) function.
Transformations
\(\begin{aligned} y=f(ax) \implies & f(x) \: \textsf{stretched/compressed horizontally by a factor of} \: a \\ & \textsf{If }a > 1 \textsf{ it is compressed by a factor of}\: a \\ & \textsf{If }0 < a < 1 \textsf{ it is stretched by a factor of}\: a \end{aligned}\)
\(y=-f(x) \implies f(x) \: \textsf{reflected in the} \: x \textsf{-axis}\)
Given parent function:
\(y=\sqrt{x}\)
Horizontal stretch:
As this is a horizontal stretch, the x variable should be multiplied by a value between zero and 1:
\(\implies y= \sqrt{\dfrac{1}{2}x}\)
Reflected in the x-axis:
To reflect a function in the x-axis, simply make the function negative:
\(\implies y=- \sqrt{\dfrac{1}{2}x}\)

A. 48/100 = 48%
B. 39/100 = 39%
C. 39/48 = 81%
D. 49/100 = 49%
Answer:
C. 39/48 = 81%
Step-by-step explanation:
To determine the percentage of females who only said they like cats using the given two-way table, we need to find the number of females who selected "cats" only and divide it by the total number of females surveyed. We can then multiply the result by 100 to get the percentage.
According to the provided two-way table:
Number of females who only said they like cats = 39
Total number of females surveyed = 48
To calculate the percentage:
Percentage of females who only said they like cats = (Number of females who only like cats / Total number of females surveyed) * 100
Percentage of females who only said they like cats = (39 / 48) * 100 ≈ 81.25%
Therefore, the correct option is:
C. 39/48 = 81%

1/10 of the M&M's in a bag are red and 1/5
are blue. What fraction of all the m&ms
are red and blue?
Answer:
3/10 of all the M & M's are red and blue.
Step-by-step explanation:
Given that 1/10 of the M & M's in a bag are red and 1/5 are blue, to determine what fraction of all the M & M's are red and blue, the following calculation must be performed:
1/10 = 0.10
1/5 = 2/10 = 0.20
1/10 + 2/10 = X
3/10 = X
Therefore, 3/10 of all the M & M's are red and blue.
write an equation for the horizontal line that passes through
the equation of the horizontal line passing through (-3, 4) is y = 4.
The equation of a horizontal line is of the form y = c, where c represents the y-coordinate of any point on the line. In this case, we are given that the line passes through the point (-3, 4). Since the line is horizontal, the y-coordinate remains constant for all points on the line.
Therefore, the equation of the horizontal line passing through (-3, 4) is y = 4. This means that no matter what x-value we choose, the y-value will always be 4.

Plug in 7=
F(7)=3(7)-9
21-9=12
The 7th term is 12
Plug in 8=
F(8)=3(8)-9
24-9=15 8th term is 15

Use Green's Theorem to evaluate: ∫C. F.ñ ds where F = ( √X+ 6y, 2x + 6y) and C is the boundary of the region enclosed by y = x – x^2’ and the x -axis (oriented positively). "
The integral ∫C F · dr using Green's Theorem is equal to the double integral ∬D curl(F) · dA, where the limits of integration are x = 0 to x = 1.
To evaluate the integral ∫C F · dr using Green's Theorem, we need to calculate the double integral of the curl of F over the region R enclosed by the curve C.
Given F = (√x + 6y, 2x + 6y) and C being the boundary of the region enclosed by y = x – x² and the x-axis, we can parametrize the curve C as r(t) = (t, t - t²) for t in the range [0, 1].
We can then compute the partial derivatives of the vector field F:
∂F/∂x = (1/2√x, 2)
∂F/∂y = (6, 6)
Calculating the curl of F:
curl(F) = ∂F/∂x - ∂F/∂y = (1/2√x - 6, 2 - 6) = (1/2√x - 6, -4)
Now, we need to find the area D enclosed by C, which is the region between the curve y = x - x² and the x-axis. To find the limits of integration, we set the curve equal to zero and solve for x:
x - x² = 0
x(1 - x) = 0
This gives us two points: x = 0 and x = 1.
Using Green's Theorem, the integral ∫C F · dr is equal to the double integral of curl(F) over the region D:
∫C F · dr = ∬D curl(F) · dA
Now, we can evaluate this double integral over the region D using appropriate limits of integration.

Use a chain rule to find dz/dt if
z = 3 cos x - sin xy; x = 1/t, y = 4t
The derivative dz/dt can be found using the chain rule. First, we differentiate z with respect to x, and then multiply it by dx/dt. Next, we differentiate z with respect to y, and multiply it by dy/dt.
The partial derivative of z with respect to x is obtained by differentiating each term of z with respect to x, giving us dz/dx = -sin(x) - ycos(xy). The partial derivative of z with respect to y is obtained by differentiating each term of z with respect to y, giving us dz/dy = -xcos(xy).
To find dx/dt and dy/dt, we differentiate x = 1/t and y = 4t with respect to t, giving us dx/dt = -1/t^2 and dy/dt = 4.
Now, we can substitute these derivatives into the chain rule formula:
dz/dt = dz/dx * dx/dt + dz/dy * dy/dt
= (-sin(x) - ycos(xy)) * (-1/t^2) + (-xcos(xy)) * 4
= sin(x)/t^2 + 4xcos(xy) - 4ycos(xy).
Therefore, dz/dt = sin(x)/t^2 + 4xcos(xy) - 4ycos(xy).

Let f (x) = 6(x²-3x + 2). Find the area below y = f(x) and above the x-axis, between x = 0 and x = 3.
The area below the curve y = f(x) and above the x-axis, between x = 0 and x = 3, is equal to 4.5 square units.
To find the area below the curve y = f(x) and above the x-axis between x = 0 and x = 3, we need to integrate the function f(x) over this interval. The integral represents the signed area between the curve and the x-axis.
Given f(x) = 6(x²-3x + 2), we can rewrite it as f(x) = 6x² - 18x + 12. To find the area, we integrate this function with respect to x from 0 to 3:
A = ∫[0,3] (6x² - 18x + 12) dx
Evaluating this integral, we get:
A = [2x³ - 9x² + 12x] from 0 to 3
Substituting the upper limit into the expression and subtracting the result for the lower limit, we have:
A = (2(3)³ - 9(3)² + 12(3)) - (2(0)³ - 9(0)² + 12(0))
= (54 - 81 + 36) - (0 - 0 + 0)
= 9 - 0
= 9 square units.
Therefore, the area below the curve y = f(x) and above the x-axis, between x = 0 and x = 3, is equal to 9 square units.

The triangle below is equilateral. Find the length of side x in simplest radical form with a rational denominator.
Answer:
x = √30
Step-by-step explanation:
For an equilateral triangle, the measure of the angle at each vertex is 60 degrees
Thus, the angle 60 faces the side measure x
Also, the given length is adjacent to the angle 60 measure
Mathematically, the trigonometric ratio that links the adjacent and the opposite is the tan
The tan is the ratio of the opposite to the adjacent
Thus;
Tan 60 = x/ root 10
x = root 10 * tan 60
x √(10 * √(3
x = √30
The length of \(x\) is required.
The length of \(x\) is \(\sqrt{30}\ \text{units}\)
In an equilateral triangle the altitude divides the side into halves.
So, the hypotenuse will be \(\sqrt{10}+\sqrt{10}=2\sqrt{10}\)
From the Pythagoras theorem we have
\(x^2+(\sqrt{10})^2=(2\sqrt{10})^2\\\Rightarrow x=\sqrt{(2\sqrt{10})^2-(\sqrt{10})^2}\\\Rightarrow x=\sqrt{30}\)
The length of \(x\) is \(\sqrt{30}\ \text{units}\)
