A circle centered in [tex]P(x_o,y_o)[/tex] an radius [tex]r[/tex] has a equation:
[tex](x-x_o)^2+(y-y_o)^2=r^2[/tex]
So, your equation wold be:
[tex](x-0)^2+(y-0)^2=8^2\Rightarrow x^2+y^2=64[/tex]
The correct circle's equation with radius 8 is,
⇒ x² + y² = 64
What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
This circle is centered at the origin, and the length of its radius is 8.
Since, The general equation of circle with center (h, k) and radius r is,
⇒ (x - h)² + (y - k)² = r²
Here, Center = (0, 0)
Radius = 8
Hence, The correct circle's equation with radius 8 is,
⇒ (x - h)² + (y - k)² = r²
⇒ (x - 0)² + (y - 0)² = 8²
⇒ x² + y² = 64
Thus, The correct circle's equation with radius 8 is,
⇒ x² + y² = 64

The surface area of a square pyramid is 125 square feet. The base length is 5 feet. What is the slant height?
Answer:
10.31 ft
Step-by-step explanation:
the base is 25 ft²
leaves 100 ft² for the 4 sides on top
so each triangle got 25ft²
the base length of the triangle is 5ft, bc it's the base length of the pyramid
so the height of the triangle is 10ft,
bc only then do we get a surface area of 25ft²
(b * h /2) for the triangle
now that we got base length and height,
let's look for the slant
we recall the pythagoras stuff to get the missing side of the triangle. but notice that we need to split the triangle in half to get a 90° angle.
leaving us with 10ft (height) and 2.5ft
slant² = 10² + 2.5²
slant² = 106.25
slant = sqrt(106.25)
slant = 10.31
What is X? (I forget how to do this)
Answer:
180-35=145
x=145
*I did not use 180 because the number on the other side is 180 i used it because a straight angle is equal to 180*
Step-by-step explanation:
Answer:
145
Step-by-step explanation:
When you get two lines crossing like this, and one of them is given as in the diagram, then the other one which shares a common ray with it, is the supplement to the given angle.
x = 180 - 35
x = 145.

Answer:
2 StartRoot 14 EndRoot
Step-by-step explanation:
To solve for q, we apply the leg rule theorem :
The hypotenus = 10 + 4 = 14
Leg 1 = q
Part1 = 4
According to the leg rule theorem :
Hypotenus / leg 1 = leg 1 / part 1
14 / q = q / 4
Cross multiply :
q * q = 14 * 4
q² = 56
q = √56
√56 = √4 * √14 = 2√14

Fraser scores 70% in a spelling test with 20 questions. How many did he get right? (Working out please)
Answer:
He got 14 right
Step-by-step explanation:
Percent means out of 100
70% means 70/100
We know there were 20 questions
We can write a ratio
70/100 = x /20
Using cross products
70*20 = 100x
1400 = 100x
Divide by 100 on each side
1400/100 = 100x/100
14 =x
He got 14 right
Answer:
I believe he got 14 right and 6 wrong
Step-by-step explanation:
if 10% is 2 questions each question is worth 5 points to make up of 100 (100 divided by 20 = 5) and there are 100 points in the quiz then every 2 right would be 10% count until you get 70% and you got your answer :) please mark brainliest and have a good day

Is the following statement possible or impossible?
Impossible
Hope this helps! :)
Answer:
Impossible
Step-by-step explanation:
Based on the Inequality Theorem, in any triangle, the sum of any two sides will be larger than the length of the thrid side. If the side lengths do not follow this rule, then that means that you can not create a triangle with such side lengths. In our case, the sum of two sides with lengths 1 and 8 is 1 + 8 = 9 and 9 is not greater than the length of the third side which is also 9. Therefore, it is impossible to build a triangle with such lengths.

Which statement about population parameters and point estimates is false? O A. o is the population standard deviation. It is usually unknown. B. p is the sample mean. It is used to estimate the population mean. C. sis the sample standard deviation. It is the square root of the variance. O D. nis the sample size. It is used to calculate the sample mean. SUBMIT
Using the Central Limit Theorem, the false statement is given by:
B. [tex]\mu[/tex] is the sample mean. It is used to estimate the population mean.
What does the Central Limit Theorem state?It states that, for a normally distributed random variable X, with population mean [tex]\mu[/tex] and population standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard error [tex]s_E = \frac{\sigma}{\sqrt{n}}[/tex].
If we have the standard deviation for the sample s, the Central Limit Theorem can also be applied.
The sample mean is given by [tex]\overline{x}[/tex], hence option B is false.

create a set of coordinates to model a relation that is linear function.
A set of coordinates to model a linear relation is (0,0), (1,1), (2,2), (3,3), and (4,4).
What is a linear relation?A straight-line link between two variables is referred to statistically as a linear relationship (or linear association).
The points on a line always form a linear relation.
Therefore, consider the line y = x.
The set of coordinates on y = x is as follows:
(0,0), (1,1), (2,2), (3,3), (4,4)... and so on.
Hence, a set of coordinates to model a linear relation is (0,0), (1,1), (2,2), (3,3), and (4,4).

Answer:
108
Step-by-step explanation:
c = b + 56

Substitute for c
(b + 56) + b = 160
2b + 56 = 160
2b = 104
b = 52
c = 52 + 56 = 108

HELP!! Create a system of equations with the solution (-4, 1)
9514 1404 393
Answer:
x -y = -5
3x +y = -11
Step-by-step explanation:
We assume you want two linear equations. Since you know a point on each line, the only thing you need to choose is the slope of the two lines through that point. We can make the slopes be +1 and -3, for example. Then the point-slope equations are ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -1 = +1(x +4)
y -1 = -3(x +4)
We can use these equations "as is", or put them in whatever form you like. I personally prefer "standard form:" ax+by=c.
First equation:
y -1 = x +4 . . . . . . eliminate parentheses
-5 = x -y . . . . . . . keep positive x term, put x and y together, separate from the constant
x - y = -5 . . . . . . standard form
Second equation:
y -1 = -3x -12 . . . . eliminate parentheses
3x +y = -11 . . . . . . add 3x+1 to both sides
