we can see that the center is (-3, 3) and the radius is 9 units.
How to find the center and radius of the circle?The general circle equation, for a circle with a center (a, b) and radius R is given by:
(x - a)^2 + (y - b)^2 = R^2
Here we have the equation:
x^2 + y^2 + 6x = 6y + 63
Let's complete squares:
x^2 + y^2 + 6x - 6y = 63
(x^2 + 6x) + (y^2 - 6y) = 63
(x^2 + 2*3x) + (y^2 - 2*3y) = 63
Now we can add and subtract 9, (two times) so we get:
(x^2 + 2*3x + 9) - 9 + (x^2 - 2*3x + 9) - 9 = 63
(x + 3)^2 + (y - 3)^2 = 63 + 9 + 9 = 81 = 9^2
(x + 3)^2 + (y - 3)^2 = 9^2
Comparing with the general circle equation, we can see that the center is (-3, 3) and the radius is 9 units.

Let ABCD be an isosceles trapezoid (AB//CD). Draw AE, BF perpendicular to CD (E, F belong to CD), Let AB = 8cm, CD = 18cm, AD = 13cm.
a) Prove that triangle ADE = triangle BCF
b) Calculate DE, CF.
c) Calculate AE.
Thanks for solving the homework
A trapezoid is a plane figure bounded by four sides. Therefore, the required answers are given below;
a) ΔADE = ΔBCF (Side-Angle-Side congruent property)
b) DE = 5 cm and CF = 5 cm
c) AE = 12 cm
Plane figures are shapes that are formed by straight boundaries referred to as sides. Examples include; square, rectangle, trapezium, etc.
A trapezoid is a family of quadrilaterals., these are figures that have four straight sides.
In the given question, the required answers are:
a) To prove that ΔADE = ΔBCF
Thus,
AE ⊥ DC (given)
BC ⊥ DC (given)
<AED = <BFC = [tex]90^{o}[/tex]
AE = BF (height of the trapozoid)
<ADE ≅ <BCF (congruent property of two triangles)
Therefore, it can be concluded that;
ΔADE = ΔBCF (Side-Angle-Side congruent property)
b) Given that AB = 8 cm, and DC = 18 cm.
Then,
CD = DE + EF + FC
18 = DE + 8 + FC (since EF = AB)
18 - 8 = 2 DE (since DE = FC)
DE = 5 cm
Thus, DE = 5 cm and CF = 5 cm
c) To determine the value of AE, we have to apply the Pythagoras theorem. So that;
[tex]/Hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]13^{2}[/tex] = [tex]AE^{2}[/tex] + [tex]5^{2}[/tex]
169 - 25 = [tex]AE^{2}[/tex]
[tex]AE^{2}[/tex] = 144
AE = [tex]\sqrt{144}[/tex]
= 12
AE = 12 cm

A sample statistic becomes more accurate as the sample size increases due to the law of large numbers.(option C)
What is the law of large numbers?The law of large numbers is a theorem in statistics that states that as the number of experiments increases, the sample mean becomes closer to the theoretical mean. The law of large numbers was first proved by Jacob Bernoulli.
For example, if you carry out an experiment to determine how many students in the US attend high school and the only person you ask tells you he does not attend high school. If you conclude the experiment based on the response of that one person, it is likely that you would conclude that on average, people in the US do not attend high school. If you ask more people, it is likely that your opinion would change and you could come to the conclusion that majority of US citizens attend high school.

Geometry Question: Determine the lengths of each side of triangles LMN and L'M'N'.
What can we conclude about all of the side lengths?
Using your knowledge about parallel lines,
why must all of the angles be congruent?
The lengths of each side of the triangle LMN are, LM = 4 units, MN = 3.606 units, and NL = 2.236 units.
The lengths of each side of the triangle L'M'N' are, L'M' = 4 units, M'N' = 3.606 units, and N'L' = 2.236 units.
We can conclude that all corresponding sides are equal, and the two triangles are congruent.
All angles must be congruent, as the image L'M'N' has been parallelly translated from the preimage LMN.
The coordinates of the image are L' (-4, 1), M' (-4, 5), and N' (-2, 2). The length of each side of the triangle LMN:
LM = √((2 - 2)² + (-6 - (-2))²),
or, LM = √((0² + (-4)²),
or, LM = √16 = 4 units.
MN = √((2 - 4)² + (-2 - (-5))²),
or, MN = √((-2)² + (3)²),
or, MN = √(4 + 9) = √13 = 3.606 units.
NL = √((4 - 2)² + (-5 - (-6))²),
or, NL = √((2)² + (1)²)
or, NL = √(4 + 1) = √5 units = 2.236 units.
The length of each side of the triangle L'M'N':
L'M' = √((-4 - (-4))² + (5 - 1)²),
or, L'M' = √((0² + (4)²),
or, L'M' = √16 = 4 units.
M'N' = √((-4 - (-2))² + (5 - 2)²),
or, M'N' = √((-2)² + (3)²),
or, M'N' = √(4 + 9) = √13 = 3.606 units.
N'L' = √((-4 - (-2))² + (1 - 2))²),
or, N'L' = √((2)² + (1)²)
or, N'L' = √(4 + 1) = √5 units = 2.236 units.
Now, since LM = L'M', MN = M'N', and NL = N'L', that, is all the corresponding sides are equal, we can conclude that all corresponding sides are equal, and the two triangles are congruent.
Since the triangles are congruent, the image L'M'N' has been parallelly translated from the preimage LMN.
Thus, all angles must be congruent, as the image L'M'N' has been parallelly translated from the preimage LMN.
Every point moves the same amount and in the same direction throughout a translation. As a result of the picture being identical in size and shape to the preimage, a translation is referred to as a rigid transformation or isometry.

2424 inches per year. Which of the following equations best describes this situation?
The equation 35 = 15-24y represent the growth rate.
According to the statement
we have given that the
A weeping willow that is 15 feet in height grows to a maximum height of 35 feet in y years at a constant rate of 24 inches per year.
And we have to describe all conditions in the equation.
So,
firstly the given height of weeping pillow before growing is 15 feet.
It means the maximum real height it grows is to subtract from the maximum given height it grows.
it means we have to find the growth rate.
real height he grows is = 35-15 = 20 feet
And it grows at the 24 inches per year so, it means it become
24 y
By combining these we get the equations is
35 = 15-24y.
So, The equation 35 = 15-24y represent the growth rate.

I am taking the Khan Academy Lesson.
Algebra 3, in the excercise size the graphs to determine the functions domain and range, x and y intercepts if any, and the functions values indicated below the graphs
Answer:
f(-4)= 3
f(3) = 4
Step-by-step explanation:
y= f(x)
which means y is a function of x
or, in simpler words what is the value of y w.r.t to x
On obseving the graph carefully, you'll see the for the x= -4 the value of y is 3
similarly, for x= 3 , y - coordinate is 4

A kite is inscribed within a square with a side lengths of 9 units.
A kite is inscribed in a square with a side length of 9 units.
What is the area of the kite?
27.5 square units
36.0 square units
40.5 square units
45.0 square units
Answer:
(c) 40.5 square units
Step-by-step explanation:
Assuming the kite is oriented so its diagonals are parallel to the sides of the square, each diagonal is 9 units long. The area of the kite is given by an appropriate formula.
What is a kite?A kite is a parallelogram with two pairs of adjacent congruent sides. Its diagonals meet at right angles. One diagonal bisects the other.
Kite areaThe formula for the area of a kite is ...
A = 1/2(d1)(d2) . . . . . where d1 and d2 are the lengths of the diagonals
In this problem, the inscribed kite has congruent diagonals, both of length 9 units.
The area of the kite is ...
A = 1/2(9)(9) = 81/2 = 40.5 . . . . square units
Geometry: complete this proof of theorem 18, ASAP!!!
(Theorem 18: if the side of one angle are parallel to the sides of another angle, right side to left side and left side to right side, then the angle are supplementary)
Supplementary angles are angles that can be summed up to give [tex]180^{o}[/tex], which is the value of the sum of angles on a line.
The required statements and reasons are given below:
Two or more lines are said to be parallel if there is no measure of the angle between them or the measure of the angle between them is [tex]180^{o}[/tex]. Thus the lines would never meet at any point even when extended to infinity.
While supplementary angles are angles that can be summed up to give [tex]180^{o}[/tex], which is the value of the sum of angles on a line.
STATEMENTS REASONS
1. < A and <B with AD ║BE, AC ║BF Given.
2. AD, AC, BE, BF Straight line.
3. <A ≅ <1 Congruent property of
