Answer: A line segment connecting two points on the circle and going through the center is called a diameter of the circle. ... Use the Distance Formula to find the equation of the circle. √(x2−x1)2+(y2−y1)2=d. Substitute (x1,y1)=(h,k),(x2,y2)=(x,y) and d=r .
How long is the arc intersected by a central angle of StartFraction pi Over 2 EndFraction radians in a circle with a radius of 4. 5 cm? Round your answer to the nearest tenth. Use 3. 14 for Pi.
The arc is the product of the angle and radius of the circle. Then the arc length is 7.065 cm.
What is a circle?It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The central angle of π/2 radians in a circle with a radius of 4.5 cm.
The arc is given as the product of the angle and radius of the circle.
[tex]\rm Arc \ length = Angle * Radius\\\\\\Arc \ length = \dfrac{\pi}{2} * 4.5\\\\\\Arc \ length = \dfrac{3.14}{2} * 4.5\\\\\\Arc \ length = 7.065[/tex]
The arc length is 7.065 cm.

What is the slope
So technically this is the graph I picked a random answer but I dibt get how the slope is 4 can you guys please explain
the answer I got was 4
Answer:
4
Step-by-step explanation:
We can use the y-y/x-x formula.
We need to find two points that are a whole number.
(0,10) -- 0 is the x coordinate, 10 is the y coordinate.
(20,90) -- 20 is the x coordinate, 90 is the y coordinate.
10-90 = -80
0-20 = -20
-80/-20 as a whole number is 4.
The slope is 4.

Answer:
Step-by-step explanation:
rise / run is another way of expressing the tangent.
So when you are told that the rise over run is 35% you mean the rise is 35% of the run.
Another way of expressing this is by saying Tan(theta) = 0.35
theta = tan-1(0.35)
theta = 19.29 degrees.
The answer is A. You can reason this out. 19 degrees is the smallest answer. If it was any larger, do you think an 18 wheeler would be able to make the grade? Likely not.

Answer:
41 -12√5
Step-by-step explanation:
All square roots of natural numbers, other than of perfect squares, are irrational.so, let the unknown irrational number be x,
solve:
√x + √5 = 6
√x = 6 - √5
( √x ) ² = ( 6 - √5 )²
x = ( 6 - √5 )( 6 - √5 )
x = 36 -6√5 -6√5 + 5
x = 41 -12√5

How do I solve this, it's not 10
Answer:
26.7
Step-by-step explanation:
This is the answer because 26.7/20 = (16+26.7)/32
When two triangles are similar, it means their sides are also proportional. The reason why it is not ten is because you need to add 10 to 16 to the large triangle as well, which no longer makes it proportional.
To solve, you create a formula.
(16+x)/32=x/20
Multiply both sides by 32 to get rid of the 32 in the left side.
16+x=32x/20
Multiply both sides by 20 to get rid of the 20 right side.
320+20x=32x
-20x on both sides to get all the variables on one side and all the nukbers on the other.
320=12x
Divide both sides by 12 to get x by itself
x=26.66667

I really really really really need help with this question
Answer:
When rotating any polygon 90 degrees, each vertice/point of the polygon should be changed from (x, y) to (y, -x). Because of this, E(-7, -4) should be E'(-4, 7), F(-2, -1) should be F'(-1, 2), and G(-5, -8) should be G'(-8, 5) after the rotation.
Step-by-step explanation:
Like I explained above, when rotating a shape 90 degrees clockwise on a plane, the points change from (x, y) to (y, -x). The student changed each point from (x, y) to (-y, x), which is a 90 degree counterclockwise rotation. That is why the student is incorrect.
I hoped this helped! Sorry, I am terrible at explaining things. :)
James has a 6-ft board that is 24 in. wide. He wants to cut it into five pieces to make a small bookshelf with two shelves. The front and back will not be covered. What should the dimensions of the bookshelf be to maximize the volume and use all of the 6 ft board?
Answer:
width=x, length = y

3x + 2y = 6y>x
y = 1.5 , x= 1

if x^2=36 and y^2=81 which of the following cannot be the value of x+y
A. -15
B. -3
C. 0
D. 3
E. 15
Answer: 0
Step-by-step explanation:
We can unsquare the squareroots:
x^2=36
Becomes
x=6 (because 6*6 is 36)
similarly,
y^2=81
Becomes:
y=9(because 9*9=81)
When you have a squareroot no matter if it’s negative or positive the result is a positive number.
Now we can solve and eliminate possible solutions.
For A) -9+(-6)=(-15)
For B) (-9)+6=(-3)
For D)(-6)+9=3
For E) 9+6=15
The only one that cannot be made is C)0

NO solution
Step-by-step explanation:
System of Linear Equations entered :
[1] y + 3x = 7
[2] y + 3x = -6
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = -3x - 6
// Plug this in for variable y in equation [1]
[1] (-3x-6) + 3x = 7
[1] 0 = 13 => NO solution

teh face of a circular game token has an area of 10pi cm to the second power. what is the diameter of the coin token. round to the nearest hundredth of a centimeter
Answer:
6.32 cm
Step-by-step explanation:
Area of a circle = [tex]\pi r^2[/tex] (where r is the radius)
Given area = [tex]10\pi[/tex] cm²
⇒ [tex]10\pi=\pi r^2[/tex]
[tex]\implies 10=r^2[/tex]
[tex]\implies r=\sqrt{10}[/tex]
Diameter = 2r (where r is the radius)
[tex]\implies d=2r=2\sqrt{10}=6.32[/tex] cm (nearest hundredth)
Area of a circle = [tex]πr²[/tex]
Given area = [tex]10π cm²[/tex]
[tex]\bold\red{ ⇒} 10π = πr²[/tex]
[tex]\bold\red{⇒ } 10 = r²[/tex]
[tex]\bold\red{⇒ } r = \sqrt{10}[/tex]
Diameter = [tex]2r[/tex]
[tex]\bold\red{⇒}2\sqrt{10} =\bold\pink{6.32 cm} [/tex] [tex]\bold\green{ [nearest \: hundredth]}[/tex]
