Answer:
[tex](x-5)^2+(y-2)^2=9\\[/tex]
Step-by-step explanation:
So, you basically want the equation of the circle.
Given:
Center(C): [tex]C(5, 2)[/tex]
[tex]r=3[/tex]
The equation of circle is:
[tex](x-h)^2+(y-k)^2=r^2\\[/tex]
Where, [tex](h, k)[/tex] represents the center point and [tex]r[/tex] is the radius of the circle.
Plotting the values in the equation:
[tex](x-5)^2+(y-2)^2=3^2\\[/tex]
[tex](x-5)^2+(y-2)^2=9\\[/tex]
This is the equation of the circle of center (5, 2) and radius 3.
Answer:
(x-5)2 + (y -2)2 = 9

17. The Cruz family is buying a custom-made cover for their swimming pool, shown below. The cover costs
$2.95 per square foot. How much will the cover cost? Round to the nearest cent.
25 tt
a
$2,627.56
c. $1,627.56
b. $1,467.56
d. $1,212.89
Answer:
The answer is is
C. $1,627.56
Step-by-step explanation:
The question is incomplete,
Kindly find attached the diagram of the poll for the dimension for your reference.
we need to first calculate the area of the pool.
Let's begin by calculating the area of the rectangular shape
A= length x width
A= 25*15
A=375ft²
Secondly the two semi circles can be solved for as a whole circle
Area of circle = πr²
Radius r= diameter/2= 15/2= 7.5ft
Area = 3.142*7.5²
A= 3.142*56.25
A= 176.7375ft²
Total surface area pool =
176.7375+375= 551.7ft²
Given that a square foot is $2.95
Hence the cost of covering the pool is 551.7*2.95=$1,627.515

Find the 4th term of the expansion of (a - sqrt(2)) ^ 8
Answer:
Applying the binomial theorem
[tex]{\displaystyle (x+a)^{n}=\sum _{k=0}^{n}{n \choose k}x^{n-k}a^{k}}[/tex]
Here we have x = -[tex]\sqrt{2}[/tex], n = 8,
=> 4th term (k = 3) would be:
[tex]{8 \choose 3}x^{8-3}a^{3}} = {8 \choose 3}(-\sqrt{2})^{5}a^{3}} = -224a^{3}\sqrt{2}[/tex]

Answer:
w = 2.5 cm
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 5 and h = 6, thus
A = 0.5 × 5 × 6 = 15 cm²
Thus the area of the rectangle is 15 cm²
A = lw ( l is the length and w the width )
Here l = 6 and w is to be found
6w = 15 ( divide both sides by 6 )
w = 2.5 cm

Answer:. GCF of first two terms is 7r^2.
GCF for last two terms is 2
Step-by-step explanation: GCF means the largest number that the terms can be divided by evenly.
7 and 14 are both divisible by 7. The factors of those terms are (7r^2)(r +2).
r^3 means r × r × r. r^2 means r × r so r^2 is a factor of r^3
2r and 4 are both divisible by 2. The factors of those terms are (2)(r +2)

Hugo reflects a vector v across the line y = –x. Nemo rotates a vector v 180° counterclockwise about the origin. Which of the following vectors would have the same image for Hugo and Nemo?
Answer:
The (3, 3) one
Step-by-step explanation:
i did the exam and got it right ;)
The vectors that have the same image for Hugo and Nemo are [3, 3].
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
To find the reflection of a vector v across the line y = -x, we can use the formula:
reflection(v) = R×v × R
where R is the reflection matrix given by:
R = [0 1]
[1 0]
To find the rotation of a vector v by 180° counterclockwise about the origin, we can use the formula:
rotation(v) = Rθ × v
where Rθ is the rotation matrix given by:
Rθ = [-1 0]
[0 -1]
Let's apply these transformations to each vector and see which ones have the same image for both Hugo and Nemo:
Reflection(d) = R × d × R = [0 1] × [3, 3] × [0 1] = [3, 3]
Rotation(d) = Rθ × d = [-3, -3]
These two vectors are equal.
Therefore, the vectors that have the same image for Hugo and Nemo are [3, 3].

The radius of a circle is 5 cm. Find its area to the nearest tenth.
Answer:
A = 78.5 cm²
Step-by-step explanation:
Area of Circle = πr²
A = (3.14)(5)²
A = (3.14)(25)
A = 78.5 cm²
The area formula of a circle is r² x π.
With that being said, we can now substitute in our radius value.
(5)² x π
From there, we can find the square root of the radius.
(25) x π
And then we can multiply by pi to solve.
78.539816..
Finally, we'll round to the nearest tenth to get our answer.
78.5
Therefore, the area of the circle is 78.5 cm.
