17.1 equation of a circle evaluate homework and practice answer key

The evaluation using the equation of circle for the practice question is (x - 4)² + (y + 11)² = 256

<h3>What is the equation of the Circle Distance Formula?</h3>

With respect to the distance formula, a point location in space (x,y) at a distance (r) from the origin is valid if \mathbf{\sqrt{x^2 + y^2} = r}. Hence this refers to the equation of the circle centered at the origin.

For Conic Sections:

  • \mathbf{(x-h)^2 (y-k)^2 = r }

where;

  • center = (h,k)
  • radius = r

Let's assume we have a circle with C(4,-11) and radius r = 16;

Then, we have:

(x-h)² +(y -k)² = r²

(x-4)² + (y - (-11))² = 16²

(x - 4)² + (y + 11)² = 256

If you divide a number into 3 equal groups and then divide each group in half, you end up with 13. The starting number is.
Vlad [161]

Answer:

The starting number is 78.

Explanation:

(x / 3) / 2 = 13

divide a number by 3 (x / 3)

divide in half (x / 3) / 2

You get 13 (x / 3) / 2 = 13

Reverse the problem.

13 * 2 = 26

26 * 3 = 78

x = 78

Plug in the number.

(78 / 3) / 2 = 13

78 / 3 = 26

26 / 2 = 13
