<h3>The equation of a circle.</h3>

Mathematically, the general form of the equation of a circle is given by;

(x - h)² + (y - k)² = r²

<u>Where:</u>

  • h and k represents the coordinates at the center.
  • r is the radius of a circle.

Based on the information provided that the center of the circle lies on the y-axis, we have:

(h, k) = (0, 4)

Radius, r = 3 units.

Substituting the given parameters into the formula, we have;

(x - 0)² + (y - 4)² = 3²

x ² + y² - 8y + 16 = 9

x ² + y² - 8y + 7 = 0.

Therefore, the set of values which might correspond to the circle are A = 1, B = 1, C = 0, D = -8 and E = 7.

Match the mean median mode and range for the data set below 16 9 20 10 12 6 8 15
blsea [12.9K]

Answer:

12 is mean     11 is median     range is 14

Step-by-step explanation:

For the Mean

Add all the numbers up

16 + 9 + 20 + 10 =55

12 + 6 + 8 + 15 = 41

55 + 41 = 96

There are 8 numbers so we divide by 8

96/8 = 12

Range is Smallest number minus biggest so 20 - 6 = 14

Answer: x = 150°

Step-by-step explanation:

The tangent intersects the circle's radius at a 90° angle, so ∠OAC = ∠OBC = 90°.

AOBC is a quadrilateral and we know that sum of interior angles of quadrilateral equals to 360°.

Now,

∠OAC + ∠OBC + ∠AOB + ∠ACB = 360°

90° + 90° + x + 30° = 360°

210° + x = 360°

x = 360° - 210°

x = 150°

gayaneshka [121]

Answer:

  48°

Step-by-step explanation:

In triangle CYZ, angles Y and C are complementary, so ...

  (5x +22) + (12x) = 90

  17x +22 = 90

  17x = 68

  x = 4

The angle of interest is 12x° , so has measure

  12·4° = 48°

Write two different two-step equations that have 1.2 as their solution.
mart [117]
We can write multiple equations that have the same solution.
 Two of these equations could be for example:
 Equation 1: 
 10x = 12 
 Equation 2: 
 2x-1 = 1.4
 Note: when clearing x in both equations we have:
 x = 1.2
 Answer: 
 10x = 12 
 2x-1 = 1.4
