Answer:

Step-by-step explanation:

circle A is

x²+y²+6x-4y-12=0

x²+6x +y²-4y =12

think (a+b)² = a²+2ab+b² we have a=x, b= 3

and (a-b)² = a²-2ab+b² so we have a=y, b=2

x²+6x +9 +y²-4y+4 = 12-9-4

(x+3)² +(y-2)²= -1

compare to the general equation of a circle (x-h)²+(y-k)² =r²

the center is at (-3,2) and the radius is √-1 =i

Circle B has center (0, -4) and radius 3 so the equation is

(x-0)²+(y-(-4))² =3²

x² +(y+4)² = 9

point (√8, -3) is on the circle if it verifies the equation

√8² +(-3+4)² = 9

8+1 =9 true so the point is on the circle

Circle A and circle B are not similar because they do not have the same center and radius

The Volume Of A Toy Box. (A cube)

Answer:

Volume of a toy box is correct.

I took the Quiz L:)

Answer:

O C. 0

Step-by-step explanation:

What is the sum of 15 and its additive inverse?

In Mathematics, the additive inverse of a number is defined as the number that when it is added to a specific number equals 0

From the above question, the additive of 15 = -15

Therefore, the sum of 15 and its additive inverse is calculated as:

15 + -15

= 15 - 15

= 0

Therefore, Option C is the correct option

Answer: C. 1/3π(7.52)(19) – 1/3π(3.52)(8)

Step-by-step explanation:

took the test and got 100

The expression that represents the volume of the frustum is:  1/3π(7.5²)(19) - 1/3π(3.5²)(8).

Volume of a frustum = Volume of bigger cone - volume of smaller cone = 1/3πR²H - 1/3πr²h

Given the following dimensions:

Applying the volume formula, we have:

Volume of the frustum = 1/3πR²H - 1/3πr²h = 1/3π(7.5²)(19) - 1/3π(3.5²)(8)

Thus, the expression that represents the volume of the frustum is:  1/3π(7.5²)(19) - 1/3π(3.5²)(8).

Answer:

Centre: [tex](\frac{1}{2} ,2)[/tex]

Radius = [tex]2[/tex]

Step-by-step explanation:

General formula for a circle: [tex](x-a)^2+(y-b)^2=r^2[/tex], where [tex]r=[/tex] the radius of the circle and [tex](a,b)[/tex] is the centre of the circle.

To find the centre and radius of the circle we should re-write the given equation in the form of the general formula.

So, put the terms with the same variables together:

[tex]4x^2-4x+4y^2+16y+1=0[/tex]

We can see that there is a common factor of [tex]4[/tex], so let's simplify by dividing by [tex]4[/tex]:

[tex]x^2-x+y^2+4y+\frac{1}{4} =0[/tex]

Here we can get it into the general formula by completing the square.

We do this by turning a quadratic with form [tex]ax^2+bx+c=0[/tex] into the form [tex](x-d)^2-e+c=0[/tex], where d is half of the coefficient of [tex]x[/tex], e is [tex]d^2[/tex] and c is the constant of the quadratic.

So let's re-write the equation of the circle:

[tex](x-\frac{1}{2} )^2-\frac{1}{4} +(y-2)^2-4+\frac{1}{4} =0[/tex]

Simplify: [tex](x-\frac{1}{2} )^2 +(y-2)^2-4} =0[/tex]

Now we can see that it's very similar to the general equation and all we have to do is bring the [tex]4[/tex] over to the right side.

[tex](x-\frac{1}{2} )^2 +(y-2)^2} =4[/tex]

So, now we can find the radius and centre.

[tex](a,b) = (\frac{1}{2} ,2)[/tex]

[tex]r^2=4, r=2[/tex]

Answer:

x=4 and y=1

Step-by-step explanation:

Step: Solvex+y=5for x:

x+y=5

x+y+−y=5+−y(Add -y to both sides)

x=−y+5

Step: Substitute−y+5forxinx−y=3:

x−y=3

−y+5−y=3

−2y+5=3(Simplify both sides of the equation)

−2y+5+−5=3+−5(Add -5 to both sides)

(Divide both sides by -2)

−2y=−2 /−2y

−2 = −2 /−2

y=1

Step: Substitute1foryinx=−y+5:

x=−y+5

x=−1+5

x=4(Simplify both sides of the equation)

Answer:

x=4 and y=1

Answer:

Option (4)

Step-by-step explanation:

Proportional relationship means,

y ∝ x

y = kx

[tex]k=\frac{y}{x}[/tex]

Here, k = proportionality constant

Therefore, if the graph of a line passes through the origin (0, 0) table will represent the proportional relationship.

From table 1,

For a point (1, 2)

[tex]k=\frac{2}{1}=2[/tex]

For another point (3, 2)

[tex]k=\frac{3}{2}=1.5[/tex]

In both the cases 'k' is not same of constant.

Therefore, table (1) is not proportional.

For table (2),

Line passes through (2, 0).

That means there is a x-intercept → (2, 0)

Therefore, table doesn't represent a proportional relationship.

For table (3),

Line passes through a point (0, 1)

It means given line has a y-intercept → y = 1

Therefore, table doesn't represent a proportional relationship.

For table (4),

Line of this table passes through two points (1, 3) and (2, 6)

[tex]k=\frac{3}{1}=3[/tex]

[tex]k=\frac{6}{2}=3[/tex]

Therefore, proportionality constant for the given table is 3.

Now we can graph table (4).

Answer:

3/5

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

the theoretical probability that the movie is not a comedy = number of movies that are not comedies / total movies available

Answer: Outsourcing

Step-by-step explanation: I just took a test.

The use of workers that use networked computers to work at lower rates of pay than American workers is called outsourcing.

The term outsourcing has to do with a situation in which workers from outside the company are contrated to do the work of the company. This could be done remotely most times by the use of a computer.

In this case, the American companies that contracted European and Asian companies, where well educated workers could do jobs on networked computers at lower rates of pay than American workers is called outsourcing.
