Explain how to use the figure below and a sequence of similarity transformations to prove that all circles are similar.
Answer:
Since every circle is 360.
so we know that their angles are congruent.
Answers
Based on similarity transformation, Since every circle is 360 degrees, so we know that their angles are congruent.
What is similarity transformations?
When a figure is transformed by a similarity transformation, an image is created that is similar to the original figure.
The total angle in every circle is 360 degrees, hence all circles are similar.
Thus, we can conclude the following based on similarity transformation, Since every circle is 360 degrees, so we know that their angles are congruent.

258 cm PLZ GIVE ME BRAINLIEST
Step-by-step explanation:
Since the chord is given as 80cm, we know from the definition of a chord that it is equidistant to both sides of the circle. Therefore, half the chord is 40. The extension of the center to the chord is perpendicular to the chord(definition of a chord). Therefore, if we connect the center of the circle to the edge of the chord, it's a right triangle. Also the center of the chord is the radius of the circle. Pytharogean theorem: 40^2 + 9^2=r^2 : 1681=r^2: r=41. The radius is 41. Curcumference of circle: pi*2*r : pi*2*41 : pi*82= 258 cm.

Answer: 55 Square inches
Step-by-step explanation:
You should find the area of the square and rectangle separately
To find the area you multiply length times width, so the area of the square is 4×4 which equals 16
Then you do the same to the rectangle, 13×3=39
To find the area of the whole figure you add the area of the two shapes together 16+39 which should give you 55

Lines RS, TV, and SW are shown. On a coordinate plane, 3 lines are shown. Line R S goes through (negative 8, 6) and (2, 6). Line T V goes through (negative 6, negative 4) and (8, negative 4). Line S W goes through (2, 6) and (2, negative 8). Which statements are true about these lines? Select three options. Line RS has a slope of 6. Line SW has an undefined slope. Line TV has a slope of 0. Lines RS and TV are parallel. Line SW is perpendicular to line RS, but not to line
Answers
Answer:
b, c, d.
Step-by-step explanation:
Statements 2) Line SW has an undefined slope, 3)Line TV has a slope of 0, and 4) Lines RS and TV are parallel are correct.
It is given that there are three lines RS, TV, and SW.
Line RS goes through (-8, 6) and (2, 6).
Line TV goes through (-6, -4) and (8, -4).
Line SW goes through (2, 6) and (2,-8).
It is required to find true statements.
Statements are:
Line RS has a slope of 6.Line SW has an undefined slope.Line TV has a slope of 0.Lines RS and TV are parallel.Line SW is perpendicular to line RS, but not to line TV.What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]m=\frac{y_{2}-y_{1}}{{x_{2}-x_{1}}}[/tex]
Where [tex](x_{1}, y_{1}) and (x_{2}, y_{2})[/tex] are points lie on the line.
1. Finding line RS slope by using the above formula:
[tex]m=\frac{6-6}{2-(-8)}[/tex]
[tex]m=0[/tex]
2. similarly finding line SW slope:
[tex]m=[/tex] ∞
3. similarly finding line TV slope:
[tex]m=0[/tex]
4. If the two lines are parallel then their slope will be equal.
The slope of RS = The slope of TV.
Hence RS and TV are parallel.
5. If two lines are perpendicular then their product of slope will be -1.
Here we can see the product of the slope of SW and RS is not defined.
Hence these two lines aren't perpendicular.
Therefore, statements 2, 3, and 4 are correct.

Notice that x^2 - 7x + 12 factors as follows: (x - 3)(x - 4), and so the original division problem
x^2 - 7x + 12 (x - 3)(x - 4)

television is regularly priced at $855. What is the total price of the television, including sales tax,
if it was purchased on sale?
Answers
Answer:
$812.25
Step-by-step explanation:
Given data
Cost of TV= $855
Discount= 10%
Tax= 5%
Let us find the amount of the Discount
=10/100*855
=0.1*855
=$85.5
Let us find the amount of the Tax
=5100*855
=0.05*855
=$42.75
Hence the cost of the TV is
=855+42.75-85.5
=897.75-85.5
=$812.25

You bought an item for $25 on Ebay and plan on marking it up 65%. What price will you sell your item for to the nearest dollar?
Answers
Answer:
$41.25
Step-by-step explanation:
The original price is $25. You want to sell it for 65% more. To find this amount, we need to find 65% of 25.
Let's make an equation.
65/100 • 25 = x
Multiply.
x = 16.25
Now we know how much you want to mark it up by.
Add this to your base of $25.
25 + 16.25
= 41.25
You want to sell it for $41.25.

V = (4, 4 )
Step-by-step explanation:
Use the midpoint formula, the equation corresponding coordinates to the coordinates of the midpoint M
let V = (x, y ) , W = (8, 6 ) , then
[tex]\frac{x+8}{2}[/tex] = 6 ( multiply both sides by 2 )
x + 8 = 12 ( subtract 8 from both sides )
x = 4
and
[tex]\frac{y+6}{2}[/tex] = 5 ( multiply both sides by 2 )
y + 6 = 10 ( subtract 6 from both sides )
y = 4
coordinates of V = (4, 4 )

The list that represents the values of x for which the function has a discontinuity is 0 and 1
How to determine the list of values?The function is given as:
[tex]f(x)=\dfrac{1}{x(x-1)}[/tex]
Start by setting the denominator to 0
x(x -1) = 0
Split the equation
x = 0 and x -1 = 0
Solve for x
x = 0 and x = 1
Hence, the list that represents the values of x for which the function has a discontinuity is 0 and 1.
