False; 2 is obviously divisible by 2, but cannot be divided by 4.

In the sequence of even positive integers {2, 4, 6, 8, 10, 12, …}, the set containing every other even number is also a counterexample:

{2, 6, 10, 14, 18, …}

<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
