an equation for a circle has formula

(x-m)² + (y-n)² = r²

where (m,n) is its center

and r is its radius

so, the equation has center (4,3) and radius 4

the equation is derived from the pythagorean theorem

Which equation represents the relationship of the measure of m∠X and m∠Y?
avanturin [10]

Answer:

The measure of f m∠X and m∠Y =180 i.e they are supplementary angles.

Step-by-step explanation:

Given:

Two angles

To Find:

Relationship between them

Solution:

For two angles to have relationship ,we need to know what represents in the figure

Here no terms are used to represent the angles

So two angles can be represented in sum of angles of triangles ,

as Consider a triangle XYZ then

X +Y=180 -Z

This will be representation

Otherwise,

<em>Then could be linear ,interior alternate angle or supplementary angles </em>

<em>Which they adds up to 180 degree.</em>

Depending upon the Condition representation will be establish.

Now,

m∠X and m∠Y=180............Supplementary angles. will be most effective .

Answer:

(x + 2)² + (y + 9)² = 49

Step-by-step explanation:

Equation:

(x - h)² + (y - k)² = r²

(x - -2)² + (y - -9)² = 7²

(x + 2)² + (y + 9)² = 49

Ethan is thinking of a negative number that is lower than -4 and higher than
s2008m [1.1K]

When the number is odd and a multiple of 3, the number that Ethan is thinking of is -9.

<h3>How to illustrate the number?</h3>

In mathematics, a multiple is the product of any quantity and an integer. It should be noted that, for the quantities a and b, it can be said that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that b/a is an integer.

In this case, Ethan is thinking of a negative number that is lower than -4 and higher than -10 and his number is odd and a multiple of 3. The number is -9 since 9 is a multiple of 3.
