Part I: Describe the center and radius of the circle.
The center is at ___.
The radius is __ units.
Part II: Use the equation below to identify the value of each variable for the circle.
Standard Form Equation of a Circle(x - h)2 + (y - v)2 = r2
(h, v) = center
r = radius length
h =__ v =__r =__
Part III: Use Parts I and II to write the standard form equation of the circle.
Answer:
Center (2,4) , radius=3, h=2 v=4 & r=3
Step-by-step explanation:
Ok so in order to find the center of the circle, use the graph (like you can see that the x is 2,if you count down from 5 to the left. the y is 4,because it's below 5 in the y pole).So the center is (2,4)
Now, in order to find the length of the radius, you need to do the following:
Take the center point (2,4) and the point where the circle ends (2,1) . Because radius is a straight, you can substract the y values of the two points : 4-1=3
As you can see in the equation, the h symbolizes the x of the center point and the v symbolizes the y.The r is the radius that we already found(3)
So it's shouldn't be a problem now to find the equation of the circle,simply replace the values with their numbers:
(x-2)^2 + (y-4)^2 = 9
The center is at (2, 4). The radius is 3 units. The value of h, v, and r are 2, 4, and 3 respectively. The standard equation of the circle is (x - 2)² + (y - 4)² = 9.
How do find the required values?The required value can be found by counting the coordinates from the given graph.
The value of the center and the radius of the circle can be found below:A diagram is provided. We should observe the diagram, we can see that the center of the circle is at (2,4) on the graph.
We can also find that the radius of the circle is 3 units by counting the lines.
The center of the circle is denoted by (h, v) = (2, 4). The radius r is 3 units.
We have found the center and the radius. We can use this to make the standard equation of the circle.
The standard equation of a circle is given by:
(x - h)2 + (y - v)2 = r2
Now substitute the values h, v and, r:
(x - 2)² + (y - 4)² = 9
Therefore, we have found that the center is at (2, 4)and the radius is 3 units. The value of h, v, and r are 2, 4, and 3 respectively. The standard equation of the circle is (x - 2)² + (y - 4)² = 9.

Does anyone mind helping me with this? It seems simple enough.
The question is: Radical x-3 = radical x + 3 (the +3 is outside of the radical). We are solving for X in this question.
Answer:
x = 4
Step-by-step explanation:
It is given that [tex]\sqrt{(x - 3)} = \sqrt{x} + 3[/tex], and we have to solve the given equation for x.
Now, we have [tex]\sqrt{(x - 3)} = \sqrt{x} + 3[/tex]
Squaring both sides we get
[tex][\sqrt{(x - 3)}] ^{2} = [\sqrt{x} + 3]^{2}[/tex]
⇒ x - 3 = x + 6√x + 9 {Since we know the formula of (a + b)² = a² + 2ab + b²}
⇒ 6√x = - 12
⇒ √x = -2
Again squaring both sides we get
⇒x = 4 (Answer)
what is 8/9 times 5/7 times 1/8 as a fraction in simplest form
Answer:
5/63
Step-by-step explanation:
8/9(5/7)(1/8)=
8/9(5/7)=
40/63(1/8)=
5/63
by the way 8/9 x 5/7 x 1/8
is also the same as (8/9)(5/7)(1/8)
To find the product of 8/9, 5/7, and 1/8, multiply the numerators and denominators to get 40/504 and simplify it to 5/63.
Explanation:To solve the multiplication of fractions, we need to multiply the numerators together and the denominators together. For the expression 8/9 times 5/7 times 1/8, we multiply the numerators 8, 5, and 1 to get 40, and the denominators 9, 7, and 8 to get 504. Simplifying the fraction 40/504 involves finding the greatest common divisor, which is 8 for both numerator and denominator, and dividing them by this number.
Doing so, we get 40 ÷ 8 = 5 and 504 ÷ 8 = 63. Hence, the solution simplified is 5/63.
Let's say you opened your laptop and positioned the
screen so it's exactly at 90° - a right angle - from your
keyboard. Now, let's say you could take the screen and
push it all the way down beyond 90°, until the back of the
screen is flat against your desk. It looks as if the angle
disappeared but hasn't. What is the angle called, and
what is the measurement?
A. Straight angle at 180°
B. Linear angle at 90°
C. Collinear angle at 120°
D. Horizontal angle at 180°
it will surely look like an angle on a straight line. which adds up.to 180,so the answer is horizontal angle at 180degrees
Final answer:
The correct answer is A. Straight angle at 180°, describing the angle formed when a laptop screen is moved from a 90° position to lying flat against the desk.
Explanation:
The question asks about the angle formed when a laptop screen is opened from a right angle (90°) to lying flat against the desk, covering a full range from vertical to horizontal. This describes a straight angle, which measures 180°. Initially, the laptop screen at a 90° angle to the keyboard represents a right angle. Pushing the screen down to lie flat transitions this to a straight angle, where the angle between the keyboard and the back of the screen spans a flat, straight line. Therefore, the correct answer is A. Straight angle at 180°.

How many total blocks will she travel if she goes to Amanda‘s house and then to Karen’s and finally back home
Answer:
19 blocks
Step-by-step explanation:
To amanda's house, it is 5 blocks (we count 1 to 6 = 5 units)
From amanda's to Karen's, is 6 units (we count from -1 to 5 = 6 units)
Now, to find Karen to own place, we have to use the Pythaogrean Theorem. It is applicable for right triangle (which is shown, Amanda's place is the right angle).
The two distance we found are the two legs of the triangle and the other side (what we need to find) is the hypotenuse (which is the side opposite of right angle). The theorem says:
Leg^2 + Another Leg^2 = Hypotenuse^2
We know the 2 legs' length, so we can solve for hypotenuse (Karen to Own place Distance). Shown below:
[tex]5^2 + 6 ^ 2 \\=25+36\\=61[/tex]
So, we have:
Hypotenuse^2 = 61
Hypotenuse = Sqrt(61) = 7.81
Rounded to nearest block, that is 8 blocks
So, total distance traveled is:
5 + 6 + 8 = 19 blocks

Hello!
Product means to multiply.
Which means it’s x added by itself y times.
For this problem it means 8 added by itself 12 times.
You can do:
8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8, which equals 96.
Or, 8 x 12.
Which is 96.
It still represents 8 + 8, etc.
But your doing it faster.
Therefore, your Product is 96.

Which rule describes the transformation?
(x, y) → (x, –y)
(x, y) → (y, x)
(x, y) → (–x, –y)
(x, y) → (–y, –x)
Answer:
The transformation used here is,
(x, y) → (-x , -y)
Step-by-step explanation:
Triangle ABC is rotated to create the image of triangle A'B'C'
Co-ordinates of A, B, C are,
A = (-1 , -1) ; B = (1 , -1) ; C = (0, -4)
Co-ordinates of A' ,B' , C' are,
A'= (1 , 1) ; B' = (-1 , 1) ; C' = (0, 4)
Hence, the transformation used here is,
(x, y) → (-x , -y)
Answer:
(x, y) → (–x, –y)
Step-by-step explanation:
Coordinates of triangle ABC:
A (-1, -1)
B (1, -1)
C (0, -4)
If we apply the transformation (x, y) → (–x, –y) we will get:
A (-1, -1) → (1, 1) which correspond to point A'
B (1, -1) → (-1, 1) which correspond to point B'
C (0, -4) → (0, 4) which correspond to point C'

Jeffrey is a kickboxing instructor who will be teaching classes at a local gym. To get certified
as an instructor, he spent a total of $200. Jeffrey will be earning a base salary of $50 per
month from the gym, plus an additional $3 for every class he teaches. If Jeffrey teaches a
certain number of classes during his first month as an instructor, he will earn back the
amount he spent on certification. How many classes will that take?
If Jeffrey takes 50 classes in his first month as an instructor, he will earn back the amount he spent on certification.
Step-by-step explanation:
Amount spent on certification = $200
Base salary = $50
Payment per class = $3
Let, x be the number of classes.
J(x) = 50+3x
He needs to earn $200 dollars in first month, therefore,
50+3x=200
[tex]3x=200-50\\3x=150[/tex]
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{150}{3}\\x=50[/tex]

The following graph is of an exponential function of the form y=a*bx.
What values of a and b would make this equation work?
a=
b=
Answer:
a= 15
b=1/3
Step-by-step explanation:
key rule: see the graph carefully to get the following identified points.from the given graph, it can be seen that, the curve passes through (0,15)by substituting this point in y=a*(b)^x,15=a*(b)^0
15=a
it can also be seen that the curve passes through (1,5)by substituting this point in y=a*(b)^x,5=a*b
5=15*b ( since, we have found that a=15 from the before steps)
dividing both the sides by 15,5/15=b=1/3
hence,a= 15
b=1/3.
