What is the center of a circle whose equation is x2 + y2 – 12x - 2y + 12 = 0?
(-12, -2)
O (-6, -1)
(6, 1)
O (12, 2)

Answers

Answer 1
The center of a circle is (6, 1)

Solution:

Given equation of circle is:

[tex]x^{2} +y^{2} -12x-2y+12=0[/tex]

Move the constant to other side

[tex]x^{2} +y^{2} -12x-2y = -12[/tex]

Group the equation

[tex](x^{2} -12x)+(y^{2}-2y)=-12[/tex]

Add 36 and 1 from both sides

[tex](x^{2} -12x +36)+(y^{2}-2y + 1)=-12 + 36 + 1\\\\(x^{2} -12x + 36)+(y^{2}-2y + 1)= 25[/tex]

Which is simplified as:

[tex](x - 6)^2 + (y-1)^2 = 25[/tex] --------- eqn 1

The equation of circle is given as:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

Where, r is radius and (h, k) is center

Compare eqn 1 with above general equation

(h, k) = (6, 1)

Thus the center of a circle is (6, 1)

Answer 2

Answer:

the center the circle is (6,1)

Answers

Answer:

PQ = 54

Step-by-step explanation:

The rest of the question is the attached figure.

As shown:

triangle RPQ is similar to triangle RTS.

So, the corresponding sides are in proportion.

[tex]\frac{PQ}{TS}= \frac{RP}{RT}[/tex]

From the figure:

TS = 36 , RP = 42 AND RT = 28

∴ [tex]\frac{PQ}{36} = \frac{42}{28} \\[/tex]

∴ PQ = 36 * 42/28 = 54

So, the distance between P and Q = 54

Which value of x would make Line segment F G is parallel to line segment B C?

Answers

Answer:

x = 9

Step-by-step explanation:

Consider the below figure attached with his question.

In the below figure [tex]FA=x+1, FB=x+6, GA=x-1\text{ and }GC=x+3[/tex].

According to Basic Proportionality Theorem (BPT), if a line is parallel to one side of a triangle, then it divides the two remaining sides in the same ratio.

Using BPT theorem,

[tex]\dfrac{FA}{FB}=\dfrac{GA}{GC}[/tex]

[tex]\dfrac{x+1}{x+6}=\dfrac{x-1}{x+3}[/tex]

On cross multiplication we get

[tex](x+1)(x+3)=(x-1)(x+6)[/tex]

[tex]x^2+3x+x+3=x^2+6x-x-6[/tex]

[tex]4x+3=5x-6[/tex]

[tex]4x-5x=-6-3[/tex]

[tex]-x=-9[/tex]

[tex]x=9[/tex]

Hence, FG║BC if the value of x is 9.

Quinn has 6 bottles of water that each weigh 3/5 pound. What is the total weight of the water bottles? Use the number line to help

Answers

Answer:

The weight of 6 bottles = [tex]3\frac{3}{5}\ pounds[/tex] or [tex]3.6\ pounds[/tex]

Step-by-step explanation:

Given:

Total number of bottles = 6

Weight of each bottle = [tex]\frac{3}{5}[/tex] pound

To find the total weight of 6 bottles.

Solution:

We can plot the number line for six bottles.

We can the plot the weights in another number line.

Each unit represents [tex]\frac{3}{5}[/tex] pound of weight.

As the number of bottles increase the number of pounds of weight increase by  [tex]\frac{3}{5}[/tex] .

Thus, weight of 6 bottles = [tex]\frac{3}{5}+\frac{3}{5}+\frac{3}{5}+\frac{3}{5}+\frac{3}{5}+\frac{3}{5}[/tex] [tex]=\frac{18}{5}[/tex] pounds

Converting fraction to mixed number.

[tex]\frac{18}{5}=3\frac{3}{5}[/tex] pounds

Or in decimals [tex]\frac{18}{5}=3.6\ pounds[/tex]

Thus weight of 6 bottles = [tex]3\frac{3}{5}\ pounds[/tex] or [tex]3.6\ pounds[/tex]

You have $512.50. You earn additional money by shoveling snow. Then you purchase a new cell phone for $249.95 and have $482.55 left. How much money do you earn shoveling snow?

Answers

You make $220 dollars shoveling snow

The person earned $220.

What is subtraction?

The process of subtracting one number from another is known as subtraction.

The person initially has $512.50.

The total money person spends is:

$249.95 + $482.55

=$732.5

Now, subtract 512.50 from 732.5 to get the money earned by the person:

$732.5 - $512.50

= $220

Common difference.​

Answers

The common difference is [tex]d=-\frac{25}{2}[/tex]

Explanation:

The difference between the 7th and 9th terms  of an arithmetic sequence is 25

Since, we know the general form of an AP is [tex]a_{n}=a_{1}+(n-1) d[/tex]

For [tex]n=7[/tex], we have,

[tex]a_{7}=a_{1}+(7-1) d[/tex]

[tex]a_{7}=a_{1}+6 d[/tex] ---------(1)

For [tex]n=9[/tex], we have,

[tex]a_{9}=a_{1}+(9-1) d[/tex]

[tex]a_{9}=a_{1}+8 d[/tex] ----------(2)

Subtracting (1) and (2), we get,

[tex]a_7-a_9=6d-8d[/tex]

Since, it is given that the difference between 7th and 9th term is 25.

Hence, we have,

[tex]25=-2d[/tex]

Dividing both sides by -2, we have,

[tex]d=-\frac{25}{2}[/tex]

Hence, the common difference is [tex]d=-\frac{25}{2}[/tex]

Find the circumference of each circle with the given radius or diameter. Round to the nearest tenth. Use 3.14 for T.
d = 14.2 mm

Answers

Answer:

C=44.6mm

Step-by-step explanation:

C=pi times d

C=3.14 times 14.2

Final answer:

The circumference of a circle with a diameter of 14.2 mm is 44.6 mm when rounded to the nearest tenth.

Explanation:

To find the circumference of a circle with a given diameter, you can use the formula C =
(D), where
is approximately equal to 3.14, and D is the diameter. For a circle with a diameter of 14.2 mm, the circumference would be calculated as follows:



C = 3.14 x 14.2 mm



After performing the multiplication:

C = 44.588 mm



When rounded to the nearest tenth, the circumference is:


C = 44.6 mm



Therefore, the circumference of the circle is 44.6 mm.

Volume of a square pyramid:

V = (1/3)a2h

Slant Height of a square pyramid:

By the pythagorean theorem we know that

s2 = r2 + h2

since r = a/2

s2 = (1/4)a2 + h2, and

s = √(h2 + (1/4)a2)

This is also the height of a triangle side

Lateral Surface Area of a square pyramid (4 isosceles triangles):

For the isosceles triangle Area = (1/2)Base x Height. Our base is side length a and for this calculation our height for the triangle is slant height s.  With 4 sides we need to multiply by 4.

L = 4 x (1/2)as = 2as = 2a√(h2 + (1/4)a2)

Squaring the 2 to get it back inside the radical,

L = a√(a2 + 4h2)

Base Surface Area of a square pyramid (square):

B = a2

Total Surface Area of a square pyramid:

A = L + B = a2 + a√(a2 + 4h2))

A = a(a + √(a2 + 4h2))

Therefore your answer is B 384.
