Given:
The vertices of a quadrilateral are v(-2,-1) w(-5,-2) x(-8,-7) and y(1,-6).
To find:
The vertices of the image of quadrilateral vwxy after 180° about the origin.
Solution:
If a figure rotated 180° about the origin, then the rule of rotation is
[tex](x,y)\to (-x,-y)[/tex]
Using this rule, we get
[tex]v(-2,-1)\to v'(2,1)[/tex]
[tex]w(-5,-2)\to w'(5,2)[/tex]
[tex]x(-8,-7)\to x'(8,7)[/tex]
[tex]y(1,-6)\to y'(-1,6)[/tex]
Therefore, the vertices of image of quadrilateral vwxy after 180° about the origin are v'(2,1), w'(5,2), x'(8,7), y'(-1,6).

Answer:
198
Step-by-step explanation:
rectangular side (9,3)
9x3=27
27x2= 54 (because there's rectangular sides)
Square end(6,3)
6x3=18
18x2=36(two square sides)
top&bottom sides
6x9=54
54xsquared2=108(two sides)
add all together
54+36+108=198cm(squared)

Find area of the shaded region.
Area of addition and subtraction, trigonometry, and sohcahtoa.
I’ve wasted many pints asking, please I ask kindly that no one puts fake answers, I truly need help with these problems and it is inconsiderate of those who post an answer for points so please respect others.
Answer:
The area of the shaded region is about 38.1 square centimeters.
Step-by-step explanation:
We want to find the area of the shaded region.
To do so, we can first find the area of the sector and then subtract the area of the triangle from the sector.
The given circle has a radius of 6 cm.
And the given sector has a central angle of 150°.
The area for a sector is given by the formula:
[tex]\displaystyle A=\pi r^2\cdot \frac{\theta}{360^\circ}[/tex]
In this case, r = 6 and θ = 150°. Hence, the area of the sector is:
[tex]\displaystyle \begin{aligned}A&=\pi(6)^2\cdot \frac{150}{360}\\ &=36\pi\cdot \frac{5}{12}\\&=3\pi \cdot 5\\&=15\pi \text{ cm}^2\end{aligned}[/tex]
Now, we can find the area of the triangle. We can use an alternative formula:
[tex]\displaystyle A=\frac{1}{2}ab\sin(C)[/tex]
Where a and b are the side lengths, and C is the angle between them.
Both side lengths of the triangle are the radii of the circle. So, both side lengths are 6.
And the angle C is 150°. Hence, the area of the triangle is:
[tex]\displaystyle A=\frac{1}{2}(6)(6)\sin(150)=18\sin(150)[/tex]
The area of the shaded region is equivalent to the sector minus the triangle:
[tex]A_{\text{shaded}}=A_{\text{sector}}-A_{\text{triangle}}[/tex]
Therefore:
[tex]A_{\text{shaded}}=15\pi -18\sin(150)[/tex]
Use a calculator:
[tex]A_{\text{shaded}}=38.1238...\approx 38.1\text{ cm}^2[/tex]
The area of the shaded region is about 38.1 square centimeters.

Can someone please help me with math
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 6 , then
y = 6x + c ← is the partial equation
To find c substitute (2, 19) into the partial equation
19 = 12 + c ⇒ c = 19 - 12 = 7
y = 6x + 7 → B
Answer:
B. y = 6x + 7
Step-by-step explanation:
Since the equation in slope: intercept form, y = mx + b, identify the slope of the line as the coefficient next to the variable x
y = 6x + 7, m = 6
Use the given slope and point to substitute into the point-slope formula
[tex]y - y1 = m (x-x1)[/tex]
Slope: intercept form:
y = 6x + 7
Point-slope form:
y - 19 = 6 (x - 2)

What is the simplified form of √45
Answer:
3√5
Step-by-step explanation:
The largest perfect square of the factors of 45 is 9. We can therefore convert √45 like this:
√9 × 5
Next, we separate the numbers inside the √ as such:
√9 × √5
√9 is a perfect square that equals 3. We can therefore put 3 outside the radical and get the final answer to square root of 45 in simplest radical form as follows:
3√5

Together they ran a total of 30 laps. Runner B ran 6 more than twice as many laps as Runner A. Part A: Write an equation for this situation. Use a variable to represent the number of laps for Runner A. Part B: How many laps did Runner A run? Part C: How many laps did Runner B run?
Answer:
Step-by-step explanation:
Number of laps run by Runner A = x
Number of laps run by Runner B = y
Runner B ran 6 more than twice as many laps as Runner A.
b = 6 + 2a
Together they ran a total of 30 laps.
a + b = 30
Part A: Write an equation for this situation. Use a variable to represent the number of laps for Runner A.
Part B: How many laps did Runner A run?
a + b = 30
b = 6 + 2a
Hence:
a + 6 + 2a = 30
3a = 30 - 6
3a = 27
a = 27/3
a = 9 laps
Part C: How many laps did Runner B run?
a + b = 30
b = 30 -9
b = 21 laps

in a continuous series the average weight of some students Is 45 kg and the sum of their weight is 540 kg find the number of students
Answer:
12.
Step-by-step explanation:
That would be sum of wieghts/average weight
= 540 / 45
= 12.
The number of students having an average of 45 kg will be 12.
What is an average?Average is defined as the ratio of the sum of the number of the data sets to the total number of the data. The average actually determines the middle value of the data.
Given that in a continuous series the average weight of some students Is 45 kg and the sum of their weight is 540 kg.
The average is calculated by the formula below,
Average = (Sum of the data) / Number
Number = ( Sum of the data) / Average
Number = 540 / 45
Number = 12
The total number of students is 12 in number.
