Equate the slopes of the opposite lines with (x,y) as the coordinates of the missing vertex.
How to find vertex of a parallelogram?
we know that in parallelogram, opposite sides are parallel and are of equal lengths. So, we can say that line joining vertices ( 5, -2 ) and ( 6, 2 ) and line joining vertices ( x, y ) and ( 0, 2 ) will be parallel, that is line AB and DC will be parallel and equal to each other in length.We know that interior angles on the same side of a transversal are supplementary. Similarly, ∠B + ∠C = 180°, ∠C + ∠D = 180° and ∠A + ∠B = 180°. Therefore, the sum of any two adjacent angles of a parallelogram is equal to 180°.The distance formula enables us to calculate the distance between two points on a coordinate grid. If those points have coordinates one, one and two, two, then the distance between them is the square root of two minus one all squared plus two minus one all squared.To learn more about parallelogram refers to:

Equate the slopes of the opposite lines with (x,y) as the coordinates of the missing vertex.
How to find vertex of a parallelogram?We are aware that a parallelogram has two opposed sides that are equally long and parallel. As a result, we may infer that the lines connecting the vertices (5, -2) and (6, 2) as well as the lines connecting the vertices (x, y) and (0, 2) will be parallel, making lines AB and DC parallel and of identical length. Interior angles on the same side of a transversal are understood to be supplementary. Similarly, B + C, C + D, and A + B all add up to 180 degrees. As a result, the sum of any two adjacent parallelogram angles equals 180°.The distance formula enables us to calculate the distance between two points on a coordinate grid.

g suppose that w(t) is a real-valued signal. prove that its fourier transform magnitude is symmetric around f
Answers
Since the Fourier transform of a real value signal is the product of the even cosine transform and the odd sine transform, it is conjugate symmetric and consequently symmetric about the frequency 0.
A real-valued signal's Fourier transform is a conjugate symmetric function, which means it is symmetric about frequency 0. This is demonstrated by the fact that a real-valued signal's Fourier transform may be expressed as the product of its cosine and sine transforms:
F(w) = Fc(w) plus Fs (w)
Where the cosine and sine transforms, respectively, are denoted by Fc(w) and Fs(w). Both the sine and cosine transforms are symmetric about the frequency zero because the sine transform is an odd function and the cosine is an even function. As a result, a real-valued signal's Fourier transform also exhibits symmetry near frequency 0.

The three interior angles of a triangle measure x°, (x-4)°, and (x+16)°. Which is the measure of one of the three angles?
OA) 48°
O B) 52°
O C) 60°
OD) 70°
Answers
=======================================================
Explanation:
Every triangle has the rule where the inside angles add to 180.
(angle1)+(angle2)+(angle3) = 180
x + (x-4) + (x+16) = 180
3x+12 = 180
3x = 180-12
3x = 168
x = 168/3
x = 56
Then we can determine each angle.
angle1 = x = 56 degreesangle2 = x-4 = 56-4 = 52 degrees (choice B)angle3 = x+16 = 56+16 = 72 degreesAs a check:
angle1+angle2+angle3 = 56+52+72 = 180
This confirms the answer is correct.

A parabola can be drawn given a focus of ((7,6) and a directrix of y=-8y=−8. What can be said about the parabola?
Answers
The parabola has a vertex at (7 , -1) has a p-value of -0.5 and it opens downwards.
How to interpret the equation of a parabola?The axis of symmetry of a parabola is basically perpendicular to the directrix and contains the focus and vertex.
Thus, the axis of symmetry is the vertical line x = 7.
The vertex lies halfway between the focus and directrix. Thus, we can say that the vertex is (7, (6 - 8)/2) = (7, -1)
Due to the fact that the vertex lies above the focus and the directrix is horizontal, then it means that the parabola opens downward.
Therefore, the focus is (7 - 8)/2 = -0.5 units below the vertex, so, p = -0.5

Write your answer as an inequality solved for c.

Answer:
Maria is able to spend less than $12.
C < 12
Step-by-step explanation:
If Maria has already spent 17 dollars, that means she has 12 dollars left. C cannot be greater than 12. It has to be less.
So think of this C < $12
So if we do the total on one side and the $17 and C on the other side of inequality we get
C + 17 < 29
It cannot be equal to 29 so that's why we don't use a less than or equal to symbol.

A logarithm is an operation used to determine the exponent of a given base number.
What is logarithm?
A logarithm is a mathematical function that describes the relationship between the power to which a number (called the base) must be raised, and the resulting value. The logarithm of a number is the power to which the base must be raised to produce that number.
Start by moving the logarithm to the left-hand side of the equation: log(x²-15) = log(2x)
Next, use the property of logarithms that log(a/b) = log(a) - log(b) to get x²-15 = 2x
then you can simplify the equation by subtracting 2x from both sides x²-2x-15=0
then factor the equation to get (x - 5)(x + 3) = 0
Finally, use the Zero Product Property to solve for x. The solutions will be x = 5 or x = -3

question content area top part 1 express the following angular speed in radians per second. 14 revolutions per second
Answers
The angular speed of 14 revolutions per second is equal to 87.96 radians per second.
Angular speed is a measure of how fast an object is rotating or revolving around an axis. It is typically measured in units of angular displacement per unit of time, such as degrees per second, revolutions per minute (RPM), or radians per second.
To convert angular speed from revolutions per second (RPS) to radians per second (RAD/s), we can use the following formula:
Angular speed (RAD/s) = 2π x Revolutions per second (RPS)
Given that the angular speed is 14 revolutions per second, we can substitute this value into the formula:
Angular speed (RAD/s) = 2π x 14 RPS
Angular speed (RAD/s) = 87.96 RAD/s
So, 14 revolutions per second is equivalent to 87.96 radians per second.

The value of side BD of the kite is 12 units
How to find the value of side BD of the kite?
In mathematics, kite is a quadrilateral which has two pairs of congruent adjacent sides.
A kite is a geometric shape which is symmetrical. It has two pairs of congruent adjacent sides, and two pairs of congruent opposite angles. The diagonals of a kite are perpendicular bisectors of each other.
Using Pythagoras theorem:
BC² = CE² + BE²
BE = √(BC² - CE²)
BE = √(10² - 8²) = 6 units
Since ΔCDE is identical to ΔBCE.
Thus, DE = BE
DE = 6 units
Since BD = BE + DE
Thus, BD = 6 + 6 = 12 units

IfIf Ryan claims that the cost of Plan A and Plan B differ a lot. The statement that best explains why Ryan was misled by the graph is: b.) The scale of intervals on the horizontal axis of both graphs is inconsistent.
The reason Ryan was misled by the graph?Based on the graph we can see that the graph is inconsistent based on the fact that the scale of intervals on the horizontal axis of Plan A graph and Plan B graph are inconsistent.
The reasons why the both graphs are inconsistent was because the lines did not intersect or are not on the same line which means that they are parallel lines.
Therefore the correct option is B.
