Determining Whether a Point Lies on a Circle

Mathematics
2 answers:
Softa [21]2 years ago

Answer:

No

Step-by-step explanation:

If the center is at (0, 0) and if (0, -9) lies on the circle, then the radius must be 9.

In this case, the equation of this circle is

x^2 + y^2 = r^2 = 9^2.

Does (8, 717) satisfy this equation?  No.  717^2 would be far outside of the circle.  the distance from the center to the point  (8, 17) is not the same as the radius

Solve. 3(x-6)-2(2x+3)=14
coldgirl [10]

Answer:

x=-38

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(x−6)−2(2x+3)=14

(3)(x)+(3)(−6)+(−2)(2x)+(−2)(3)=14(Distribute)

3x+−18+−4x+−6=14

(3x+−4x)+(−18+−6)=14(Combine Like Terms)

−x+−24=14

−x−24=14

Step 2: Add 24 to both sides.

−x−24+24=14+24

−x=38

Step 3: Divide both sides by -1.

−x

−1

=

38

−1

x=−38

Please help, I’m not sure what the answer is.
Karo-lina-s [1.5K]

Answer:

The answer is 'C'

Step-by-step explanation:

Congruent simply means "the same." When a line divides two parralel lines transversals are created. This means that there are angles on both lines that are similar. To fully understand which angles would be the same, I reccommend researching "transversals" for more information, or asking your teacher about it as it is hard to explain without a proper diagram.

Identify the response variable and whether the setting involves a single sample, a matched pairs, or two independent samples.
Helga [31]

Answer:

1. single sample design

2. matched pairs

3. two independent samples.

Step-by-step explanation:

the response variable is known as the dependent variable, it is the variable that the researcher is interested i finding. the response variable is the x variable that responds to changes in the independent variable.

1.

In this question the researcher has only one sample that is the specimen. that is the reference specimen that she obtained. Therefore it is a single sample design.

the response variable here is the measurement of concentration.

2. In this question we have two pairs, men and women. The researcher is interested in comparing attitudes as she interviews them. so response variable is attitude or behavior

3. this is a 2 independent sample design. The researcher is using two different methods to test and their average is being compared.

Find the sum<br>7/8+3/4 ​
ICE Princess25 [194]

Answer as an improper fraction =  13/8

This is equivalent to the mixed number   1 & 5/8

In decimal form, 13/8 = 1.625

=========================================

Work Shown:

3/4 = (3/4)*(2/2)

3/4 = (3*2)/(4*2)

3/4 = 6/8

----------

7/8 + 3/4

7/8 + 6/8

(7+6)/8

13/8

So 7/8 + 3/4 = 13/8

Which equation can be used to represent the statement?
AfilCa [17]

Answer:

I would say 16=1.2n+(negative 8) because they are in the same order as it was spelled in words and not numbers that's how I know that it could be 16=1.2n+(negative 8).
