Answer:
10. It is a parallelogram.
11. The parallelogram is a rhombus.
Step-by-step explanation:
10. Use the given sets of congruent segments with congruent vertical angles XNY and WNZ to prove that triangles XNY and ZNW are congruent. Now use CPCTC to show that angles XYN and ZWN are congruent. They are alternate interior angles making sides XY and WZ parallel. Now use CPCTC to show that sides XY and WZ are congruent. Since a quadrilateral has two opposite sides that are both parallel and congruent, the quadrilateral is a parallelogram.
11. A rectangle and a square have 4 right angles. If you add 72 deg and 72 deg, you get 144 deg which is not a right angle. Since one angle of the parallelogram is not a right angle, the parallelogram is not a square or a rectangle.
There are two triangles. Let's look at the upper triangle. The triangle has 2 angles measuring 72 deg each. That means the opposite sides are congruent, and the triangle is isosceles. Since the quadrilateral is a parallelogram, opposite sides are congruent, so all 4 sides are congruent, and the parallelogram is a rhombus.

Kelley ate 3/5 of her brownies on Monday and 6/8 of her brownies Tuesday. If Kelley originally had 2 brownies, what fraction brownie is left over? Simplifty your answer
Answer:
[tex]\frac{13}{20}[/tex]
Step-by-step explanation:
First, we need to add the two fractions together. To do this we need to make the denominator a factor of both 8 and 5. Easy way to do this is to multiply each fraction by the denominator of the other fraction:
[tex]\frac{3}{5} * 8 = \frac{24}{40}[/tex]
[tex]\frac{6}{8} * 5 = \frac{30}{40}[/tex]
[tex]\frac{24}{40} + \frac{30}{40} = \frac{54}{40}[/tex]
We can also show 2 brownies as [tex]\frac{2}{1}[/tex] or [tex]\frac{80}{40}[/tex]
Now we can subtract the two:
[tex]\frac{80}{40} - \frac{54}{40} = \frac{26}{40}[/tex]
Simplify the fraction down by dividing by two:
[tex]\frac{13}{20}[/tex]
Which is the fraction of brownie left!

A polynomial function has -5√3i as a root. Which of the following must also be a root of the function?
-5-√3i
-5+√3i
5-√3i
5+√3i
Answer:
-5+√3i is the given root so -5-√3i must be the other root
Step-by-step explanation:
We know that complex roots must come in pairs. The pairs are complex conjugates. (a+bi) and (a-bi)
You are missing a sign between -5 and the square root
So if - 5+ sqrt(3) i is a root, then -5 - sqrt(3) i must be a root
if -5 - sqrt(3)i is a root, then -5 + sqrt(3)i must be a root.
I will assume you missed a + sign
-5+√3i is the given root so -5-√3i must be the other root

What is the equation of the graph below? A graph shows a parabola that opens up and crosses the x axis at negative two and negative four. y = − (x − 3)2 + 1 y = − (x + 3)2 + 1 y = (x − 3)2 − 1 y = (x + 3)2 − 1
Answer:
[tex]y=(x+3)^{2} -1[/tex]
Step-by-step explanation:
General equation of a parabola that opens up is [tex]y=a(x-h)^{2} +k[/tex] , a>0
So equation becomes [tex]y=(x-h)^{2} +k[/tex] which implies option A and option B can never be true for this parabola.
Also this parabola's vertex lies in 3rd quadrant where coordinates of both x and y will be negative.
So, the equation of parabola will be of the form [tex]y=(x+h)^{2} - k[/tex]
Hence, option 4 that is [tex]y=(x+3)^{2} -1[/tex] is correct.
The correct equation of the graph is: x² + 6x - 35y + 8 = 0.
The equation of the graph shown, which is a parabola that opens upwards and crosses the x-axis at -2 and -4, can be determined by examining its key features.
The fact that the parabola opens upward indicates that the coefficient of the squared term (x²) in the equation must be positive.
The parabola crosses the x-axis at -2 and -4. This means that the two x-intercepts are -2 and -4.
Putting this information together, we can form the equation:
y = a * (x - r1) * (x - r2)
where 'a' is a positive constant (coefficient of x²), and r1 and r2 are the x-intercepts.
Since the x-intercepts are -2 and -4, the equation becomes:
y = a * (x - (-2)) * (x - (-4))
y = a * (x + 2) * (x + 4)
Now, let's find the value of 'a.' We are given that the parabola passes through the point (3, 1). We can substitute these coordinates into the equation to find 'a':
1 = a * (3 + 2) * (3 + 4)
1 = a * 5 * 7
a = 1 / (5 * 7)
a = 1 / 35
Now that we have the value of 'a,' we can finalize the equation:
y = (1/35) * (x + 2) * (x + 4)
Expanding the equation:
y = (1/35) * (x² + 6x + 8)
To put the equation in standard form, we can multiply both sides by 35 to eliminate the fraction:
35y = x^2 + 6x + 8
Finally, rearrange to get the equation in standard form:
x² + 6x - 35y + 8 = 0
So, the correct equation of the graph is: x² + 6x - 35y + 8 = 0.

How many hours did the trip take?
A) 3 hours
B) 6 hours
C) 8 hours
B) 6 hours
Step-by-step explanation:Let h represent the total trip time. Then h/2 is the time spent traveling at each speed. The distance covered is ...
... distance = speed · time
The sum of the distances in each mode is the total distance.
... 1020 = 55·h/2 +285·h/2

Refer to the table of long distance rates. Write an expression that can be used to find the cost of an n-minute long distance call, where n is at least 5 minutes.
Answer:
a(n) = 0.55 + (n -5)0.07
Step-by-step explanation:
The cost goes up $0.07 for each additional minute, so that is the slope of the linear function. In point-slope form the equation can be written ...

Lucy and Ethel’s favorite store was having a sale. Lucy bought 10 shirts and 4 pairs of jeans and spent $280. Sabrina bought 12 shirts and 5 pairs of jeans and spent $344.
Assuming that each shirt was the same price, and each pair of jeans was the same price, how much did each shirt and each pair of jeans cost? Write a system of equations to represent this situation. Then solve for the solution using the elimination method.
Final answer:
By defining variables for the prices and setting up a system of equations, we determine that each shirt costs $12 and each pair of jeans costs $40 after solving the system using the elimination method.
Explanation:
The subject of this question is a problem involving systems of equations, which falls under the category of Mathematics. We are given a scenario where Lucy and Ethel are buying clothing at the same prices, but in different quantities and we need to determine the cost of each item. First, let's define variables: let s be the price of a shirt and j be the price of a pair of jeans. We then have two equations based on the purchases:
10s + 4j = $280 (Lucy's purchase)12s + 5j = $344 (Sabrina's purchase)To solve these equations using the elimination method, we will multiply the first equation by 5 and the second by 4 to eliminate the jeans variable:
50s + 20j = $140048s + 20j = $1376Subtract the second equation from the first:
2s = $24Now divide by 2 to find the price of one shirt:
s = $12 (price of a shirt)We can substitute s = $12 into the first original equation to find the price of a pair of jeans:
10(12) + 4j = $280120 + 4j = $2804j = $160j = $40 (price of a pair of jeans)Quadrilateral ABCD is inscribed in this circle.

By which matrix should you multiply vector [1 3] to rotate it 180°?
Answer:
B
Step-by-step explanation:
Rotation 180° is accomplished by negating both the x- and y-coordinates. That is, you multiply each of them by -1. You want the opposite of the identity matrix, so matrix B.
We have that the Rotation of matrix [tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex] will be rotated 180 degree if [tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex] is multiplied by [tex]\begin{pmatrix}-1 & 0\\0 & -1\end{pmatrix}[/tex]
Option D is correct
From the Question we are given
[tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex]
it is important to note that the rotation of the identity matrix [tex]\begin{pmatrix}1 & 0\\0 & 1\end{pmatrix}[/tex] rotating across the Cartesian co-ordinate is a [tex]180 \textdegree[/tex] is going to give a matrix [tex]\begin{pmatrix}-1 & 0\\0 & -1\end{pmatrix}[/tex]
Therefore
The Rotation of matrix [tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex] will be rotated 180 degree if [tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex] is multiplied by [tex]\begin{pmatrix}-1 & 0\\0 & -1\end{pmatrix}[/tex]

A rectangular field is 115 meters long and 70 meters wide. Give the length and width of another rectangular field that has the same perimeter but a larger area
To find a rectangular field with the same perimeter but a larger area than the original field (115m x 70m), we should search for dimensions that sum up to half of the perimeter (185m) and form a shape closer to a square. An example would be a field measuring 92.5m by 92.5m, which has the same 370m perimeter but a larger area.
Explanation:You have asked about the length and width of another rectangular field that has the same perimeter but a larger area than a field measuring 115 meters in length and 70 meters in width. To find the dimensions of such a field, we must first calculate the perimeter of the original field.
The formula for the perimeter (P) of a rectangle is P = 2(length + width). Plugging in the given dimensions, we get P = 2(115m + 70m) = 2(185m) = 370 meters. Now we need to find dimensions that add up to half this perimeter, since length + width = P/2, which is 185 meters, but form a rectangle with a larger area.
Area (A) is calculated by the formula A = length x width. To maximize the area for a given perimeter, the rectangle should be closer to a square because a square has the largest area for a given perimeter. Hence, the dimensions we are looking for should be closer to each other compared to the original dimensions of 115m x 70m.
An example of dimensions that meet these criteria would be 92.5 meters by 92.5 meters. Although this results in a square, it fulfills the condition of having the same perimeter (since 2(92.5m + 92.5m) = 370m) but a larger area (92.5m x 92.5m = 8556.25 square meters) than the original rectangular field (115m x 70m = 8050 square meters).

After m months the height of a plant is 10 + 3m millimeters. How tall is the plant after 8 months? Three years?
Answer:
A. 34 millimeters.
B. 118 millimeters.
Step-by-step explanation:
We have been given that after m months the height of a plant is [tex]10+3m[/tex] millimeters.
To find the height of plant after 8 months we will substitute m=8 in our given expression.
[tex]\text{The height of plant after 8 months}=10+3\times 8[/tex]
[tex]\text{The height of plant after 8 months}=10+24[/tex]
[tex]\text{The height of plant after 8 months}=34[/tex]
Therefore, the height of plant after 8 months will be 34 millimeters.
B. Now let us find height of plant after 3 years.
First of all we will convert 3 years into months by multiplying 3 by 12 as 1 year equals to 12 months.
[tex]\text{3 years}=3*12\text{ months}=36\text{ months}[/tex]
Now let us substitute m=36 in our given expression.
[tex]\text{The height of plant after 36 months}=10+3\times 36[/tex]
[tex]\text{The height of plant after 36 months}=10+108[/tex]
[tex]\text{The height of plant after 36 months}=118[/tex]
Therefore, the height of plant after 3 years (36 months) will be 118 millimeters.
What is an equation of the line that is perpendicular to y=−23x+5 and passes through the point (2, 11) ?
Answer:
The equation would be y = 1/23x - 251/23
Step-by-step explanation:
To start, you need to locate the slope of the first equation. Since the slope is the coefficient of x, we know it to be -23. Now, the perpendicular slope is the opposite and reciprocal of that, which makes the new slope 1/23.
Now that we have this, we can use the point and the slope in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 11 = 1/23(x - 2)
y - 11 = 1/23x - 2/23
