Proving That All Circles Are Similar give: cicrcle x with radius r and circile y with radius s prove: circle x is similar to circle y
Answers
Answer:
Two shapes are similar when they have the same shape while their sizes may be the same or different
Therefore, two similar shapes are shapes that have a relationship such that the dimensions of one of the shapes can be obtained from the dimensions of the other shape by multiplying by a scale factor
All circles have the same shape and are defined by their center and radius
Given circle with center at 'x' and radius 'r' and circle with center 'y' and radius 's', then there exist a scale factor a = s/r such that we have;
r × a = s
Where a = s/r, we get;
r × s/r = s
We can therefore, obtain a circle with with the same size as the circle with center 'y' and radius 's' by multiplying the radius of the circle with center at 'x' and radius 'r' by a
Therefore the circle with center at 'x' and radius 'r' is similar to the circle with center 'y' and radius 's'

Answer:
Circumference = 62.8
Step-by-step explanation:
The equation for discovering a circle's circumference is simple:
-------------------------------------------------------
C = 2πr
C is the circumference (how long is the circle around)
R is the radius (half of the width of the circle)
--------------------------------------------------------
So, instead of giving us the radius, they gave us the diameter. (the full width of the circle) So, we divide that by 2 to get the radius.
20/2=10
Now, time to fill in the equation.
C = 2π10
C = 20π
C = 62.8

What is the slope
Will the line be solid or dotted
Answers
Given:
The inequality is:
[tex]y>5x+3[/tex]
To find:
The y-intercept, slope and type of line (solid or dotted).
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is the y-intercept.
We have,
[tex]y>5x+3[/tex]
The relation equation is:
[tex]y=5x+3[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=5[/tex]
[tex]b=3[/tex]
It means the slope is 5 and the y-intercept is 3.
The sign of the inequality in the given inequality is ">". It means the boundary line is not included in the solution set. So, the boundary line is a dotted line.
Therefore, the slope is 5, the y-intercept is 3 and the line is a dotted line.

Answers
Answer:
-3 and -2
Step-by-step explanation:
7x² + 19x + 21 = 4x² + 4x + 3
combine like terms:
3x² + 15x + 18 = 0
3(x² + 5x + 6) = 0
(x + 3)(x + 2) = 0

YZ = 6.93
Step-by-step explanation:
Find the complete question attached
From the diagram, we are to look for YZ
Given the following
XY = adjacent = 6
measure of m<Y = 30degrees
Required
YZ = hypotenuse
Using the SOH CAH TOA identity
Cos theta = adjacent/hypotenuse
Cos 30 = XY/YZ
Cos 30 = 6/x
x = 6/cos30
x = 6/0.8660
x = 6.93
Hence the length of YZ is 6.93

The area of a rectangle is 8w + 18 square feet. The length of the rectangle is 2 feet. Use factoring to write an expression to represent the width of the rectangle.
Answers
Answer:
The expression that represents the width of the rectangle is 4w + 9
Step-by-step explanation:
The formula of the area of the rectangle is A= length x width
The area of a rectangle is 8w+18 square feet.
A= 8w+18
The HCF of 8 and 18 is 2
Divide each term of the area by 2 to get 2 as a common factor
8 /2 =4 and 18 /2 = 9
A=2(4w+9)
The length of the rectangle is 2 feet
Substitute it in the formula of the area above
A=2 x width
A=2 width
Equate the two right sides of the area
2 width =2(4w+9)
Divide both sides by 2
The width = 4w+9

Answer/Step-by-step explanation:
1. x*21 = 24*14 (intersecting chords theorem)
21x = 336
x = 336/21
x = 16
2. 27*x = 45² (secant-tangent rule)
27x = 2,025
x = 2,025/27
x = 75
3. (x + 5)*5 = (4 + 6)*6 (Intersecting secants theorem)
5x + 25 = (10)*6
5x + 25 = 60
5x = 60 - 25
5x = 35
x = 35/5
x = 7
4. (4x + 2)*8 = (5x + 1)*7
32x + 16 = 35x + 7
Collect like terms
32x - 35x = -16 + 7
-3x = -9
x = -9/-3
x = 3

Which study appears to look for an association between two variables without actively manipulating either one. What are those variables ?
Solution :
The second study in the context is involved in asking for a random sample of the students at an university to provide a report the average hours of sleep that everybody get each night and also the grade point of their college appears for association between these two variables without actively changing either of one.
These variables are the grade point average of the students and the numbers of hours of sleep.

34
explanation:
First of all, put the numbers in order
30, 31, 31, 32, 33, 35, 35, 35, 36, 36
Then, find the middle number.
In this case, there is an even amount of numbers so, we have to pick the 2 middle numbers which is 33 and 35.
Now all you have to do is add these two numbers together then divide by 2 which will give you 34.
or, in simpler questions like this one, you can just say 34 as you know it is between 33 and 35.
In other questions, it might have and odd amount of numbers, for example:
3, 3, 5, 8, 10
so all you would do here is pick the middle number which would be 5. (it has 2 numbers on each side of it)

The interior angles of a triangle a add up to 180. We can find x by subtracting everything from 180, and then divide for x.
180 = x + 4 + 68 + x
Simplify.
180 = 2x + 72
Subtract 72 from both sides of the equation.
108 = 2x
Divide each side by 2.
x = 54
The angles of the triangle are:
Angle S = 54
Angle U = 58
Angle T = 68
