circumference of 22 cm?
Answers
Answer:
The formula for the circumference of a circle is C = 2πr, where r is the radius and C is the circumference. The equation solved for r is r =c/2π .
Step-by-step explanation: hope this helped!
Answer:
The radius of the circle with circumference 22cm is 3.5 cm
Step-by-step explanation:
The circumference of circumference of a circle is the distance of its closed boundary.
The circumference of a circle with radius r is given by the formula:
[tex]C = 2\pi r[/tex]
Given
C = 22cm
Putting the values in the formula
[tex]22 = 2 * \frac{22}{7} * r\\22 = \frac{44}{7} * r\\r = \frac{7}{44} * 22\\r = \frac{7}{2}\\r = 3.5cm[/tex]
Hence,
The radius of the circle with circumference 22cm is 3.5 cm

The trend line passes through points (2,5) and (6,11). What is the slope of the trend line?
What is the y-intercept of the trend line?
Y=___X +___
Answers
Answer:
slope = 3/2
y intercept = 2
y = 3/2x + 2
Step-by-step explanation:
to find the slope you will you (y₂-y₁) ÷ (x₂-x₁)
(11-5) ÷ (6-2) =
6 ÷ 4 = 3/2
slope = 3/2
to find the y intercept you with use the slope intercept formula (y = mx+ b) and use one point given for x and y
for the example im going to use the point (2,5)
5 = 3/2 (2) + b
5 = 3 + b
subtract three from both sides to find b (y-intercept)
b = 2

Rectangle JKLM undergoes a sequence of transformations, resulting in rectangle J’K’L’M’. The length of side K’L’ is 6 units. The coordinates of vertex K’ are (-3, 2), and the coordinates of vertex M’ are (3, -2). Describe a sequence of transformations to rectangle JKLM that would result in rectangle J’K’L’M’.
Answers
Answer:
J,F,K
Step-by-step explanation:
J,F,K
A sequence of transformations to rectangle JKLM that will result in rectangle J'K'L'M' is a translation by 3 units and -4 units, a reflection about the y-axis, and a rotation of 90 degrees counterclockwise about the origin.
What is a rectangle?A rectangle is a quadrilateral with four right angles and four sides of equal length. It is one of the most common shapes in nature and is found in everything from architecture to floor patterns.
Now, In order to transform rectangle JKLM into J'K'L'M', a series of transformations must be applied.
The first transformation is a translation of the rectangle along the x-axis by 3 units and along the y-axis by -4 units.
This will move the original rectangle from its original position, JKLM, to the new position, J'K'L'M'.
Next, a reflection about the y-axis needs to be applied, which will flip the rectangle around the y-axis.
This will result in the length of side K'L' being 6 units.
Finally, a rotation about the origin needs to be applied. The rotation should be 90 degrees counterclockwise in order for the coordinates of vertex K' to be (-3,2) and the coordinates of vertex M' to be (3,-2).
Therefore, a sequence of transformations to rectangle JKLM that will result in rectangle J'K'L'M' is a translation by 3 units and -4 units, a reflection about the y-axis, and a rotation of 90 degrees counterclockwise about the origin.

How do I solve this problem and check all the solutions?
Answers
Answer:
x-5=sqrt(2x+5)
then square both sides
x2-10x+25=2x+5
x2-8x+20=0
rest is trivial
Step-by-step explanation:
Answer:
x = 10
Step-by-step explanation:
Given
x - [tex]\sqrt{2x+5}[/tex] = 5 ( subtract x from both sides )
- [tex]\sqrt{2x+5}[/tex] = 5 - x ( divide all terms by - 1 )
[tex]\sqrt{2x+5}[/tex] = x - 5 ( square both sides )
2x + 5 = (x - 5)²
2x + 5 = x² - 10x + 25 ( subtract 2x + 5 from both sides )
0 = x² - 12x + 20 ← in standard form
0 = (x - 2)(x - 10) ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 10 = 0 ⇒ x = 10
As a check
Substitute these values into the left side of the equation and if equal to the right side then they are the solutions
x = 2
2 - [tex]\sqrt{4+5}[/tex] = 2 - [tex]\sqrt{9}[/tex] = 2 - 3 = - 1 ≠ 5
Thus x = 2 is an extraneous solution
x = 10
10 - [tex]\sqrt{20+5}[/tex] = 10 - [tex]\sqrt{25}[/tex] = 10 - 5 = 5 = right side
Thus x = 10 is the solution

In a bag of coloured jellybeans, the ratio of yellow to orange to red is 6 : 5 : 4. If there are 60 jellybeans in the bag, how many of each colour are there?
Answers
Orange: 20
Red: 16
Explanation:
6 + 5 + 4 = 15
60 / 15 = 4
Y : 6 x 4 = 24
O: 5 x 4 = 20
R: 4 x 4 = 16
Based on the ratio of the jellybeans and the number of jellybeans, the number of each is:
Yellow = 24 jellybeansOrange = 20 jellybeans Red = 16 jellybeansTo find the number of yellow jellybeans:
= Ratio of Yellow/ Sum of ratios x Number of jellybeans in total
= 6 / (6 + 5 + 4) x 60
= 24 yellow jellybeans
Orange jellybeans:
= 5 / 15 x 60
= 20 orange jellybeans
Red jellybeans:
= 4 / 15 x 60
= 16 red jellybeans
In conclusion, there are several colors of jellybeans.

Find the equation of the line through point (10,4) and parallel to 3x+5y=8.
Answers
Find slope of 3x + 5y = 8
Turn into y = mx + b
5y = -3x + 8
Divide by 5
y = -3/5x + 8/5
Slope is -3/5
Y = -3/5x + b, find y intercept
Plug in the point
4 = -3/5(10) + b
4 = -6 + b, b = 10
Final equation: y = -3/5x + 10
[tex]3x+5y=50[/tex] is the equation of the line through point (10,4) and parallel to 3x+5y=8.
How to solve equation of the line through point and parallel to a given line?We can write the equation of a line parallel to a given line if we know a point on the line and an equation of the given line. y=2x+3 . Parallel lines have the same slope. The slope of the line with equation y=2x+3 is 2 .
Given
Equation of the line is 3x + 5y = 8.
Point = (10, 4)
First we find the slope of the line 3x + 5y = 8 by replacing it into slope intercept form:
[tex]3x + 5y = 8[/tex]
⇒ [tex]5y = -3x + 8[/tex]
⇒ [tex]y = \frac{-3}{5} x + \frac{8}{5}[/tex]
Therefore, the slope of the line is m = [tex]\frac{-3}{5}[/tex].
Now since the equation of the line with slope m passing through a point [tex](y-y_{1} )=m(x-x_{1})[/tex]
⇒ [tex]y - 4=\frac{-3}{5} (x-10)[/tex]
⇒ [tex]5(y-4)=-3(x-10)[/tex]
⇒ [tex]5y-20=-3x+30[/tex]
⇒ [tex]3x+5y=30+20[/tex]
⇒ [tex]3x+5y=50[/tex]
Hence, [tex]3x+5y=50[/tex] is the equation of the line through point (10,4) and parallel to 3x+5y=8.
