Answer:

The equation of the circle is [tex](x - 2)^2 + (y - 7)^2 = 21[/tex]

Step-by-step explanation:

Equation of a circle:

The equation of a circle, with center [tex](x_0,y_0)[/tex] and radius r is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

Distance between two points:

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Diameter at the points (7,8) and (-3,6).

The diameter is the distance between these two points, so:

[tex]D = \sqrt{(-3-7)^2+(6-8)^2} = \sqrt{104}[/tex]

Radius is half the diameter, so:

[tex]r = \frac{\sqrt{104}}{2} = \frac{\sqrt{104}}{\sqrt{4}} = \sqrt{\frac{104}{4}} = \sqrt{21}[/tex]

So

[tex]r^2 = (\sqrt{21})^2 = 21[/tex]

Center:

Midpoint of the diameter, which is the mean of the coordinates. So

[tex]x_0 = \frac{7 - 3}{2} = \frac{4}{2} = 2[/tex]

[tex]y_0 = \frac{8 + 6}{2} = \frac{14}{2} = 7[/tex]

Then

[tex](x - 2)^2 + (y - 7)^2 = 21[/tex]

Answer:

Linear function

Step-by-step explanation:

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1.

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1

, the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not a linear equation.

Answer:

B) x = 20

Step-by-step explanation:

All triangle interior angles add up to 180 so:

x + 5 + 7x - 5 + x = 180

9x = 180

x = 20

Answer:

I think it C because I know that Nalia isn't correct so it's not D or B.

Square part of perimeter = 40.

Half circle = 25.135.

Together 65.135 is perimeter.

Area of square: 192

Are of half circle: 100.53.

Together 292.53

Rounded =292.48 I guess, its the most logical option since I don't see it and the only one that fits perimeter answer.

So its the 3rd question I believe, you may want to double check.

Hit the heart if it was helpful.

The perimeter and total area of the composite shape are; 292.53 and 65.135 .

The area of a square can be calculated as the square of the sides of a given figure.

The area of a square = side x side

The Square part of perimeter = 40.

Half circle = 25.135.

The perimeter = 40 + 25.135 = 65.135 is perimeter.

The Area of square = 192

Are of half circle: 100.53.

Together 292.53

Rounded =292.48

Therefore, the perimeter and total area of the composite shape are; 292.53 and 65.135 .

Answer:

The lengths of the sides are  - 11, 18, 33

Step-by-step explanation:

Shortest side = x

Second side = 3x

Third side = 7 + x

Perimeter = sum of all three sides

62 = x + 3x + x + 7

62 = 5x + 7

55 = 5x

x = 11

Shortest side = x = 11

Second side = 3x = 33

Third side = 7 + x = 18

Answer:

x = 85, y = 45

Step-by-step explanation:

95 = 50 + y (exterior angle theorem)

y = 45

180 = y + x + 50 (Angle sum property)

180 = 45 + x + 50

180 = 95 + x

x = 85

Answer:

you would pay $11.04

Step-by-step explanation:

$12 x .08= .96

$12 - 0.96 = $11.04

Answer:

11.04

Step-by-step explanation:

So, a ticket cost 12$.

We need to find the price when it of 8% off, whihc is tecnically 92% of the orginal price.

Putting this into decimal form:

0.92

So to find this price, we need to multiply the orginal price by the percentage:

12*0.92

0.02*12 is 2*24 adding 2 decimals which equals 0.24

0.9*12 is 12*9 adding 1 deecimal which equals 10.8

Add them together: 0.24+10.8 = 11.04

So 11.04 is our new cost.

Hope this helps!

Answer:

(2, 4)

Step-by-step explanation:

y = x + 2

3x + y = 10

3x + (x + 2) = 10

4x + 2 = 10

4x = 8

x = 2

y = (2) + 2

y = 4

Step-by-step explanation:

3x + y = 10

substituting the value of y = x + 2

=>3x + x+2 = 10

=>4x= 10-2

=>4x= 8

=>x= 8/4

=>x= 2

And, y= 2+2 = 4

Answer:

0.04

Step-by-step explanation:

For a density curve, total area = 1

Probability lies in between 0 and 1

The Area of triangle :

Area = 1/2 base * height

Base = 0 - 50 = 50

Area = 1

Hence,

1 = 1/2 * 50 * h

1 = 50h / 2

2 = 50h

h = 2 / 50

h = 0.04
