Given that the center of a circle is C(-10,-7) and the point S(4,4) lies on the circle's edge calculate the circle's radius to t

fredd [130]

Answer:

$r\approx 17.80$

Step-by-step explanation:

<u>Equation of the Circle</u>

A circle can be completely defined knowing its center and radius. The radius is the distance from the center to any point in its edge. Since we know the center of the circle is (-10,-7) and one point in its edge is (4,4), we calculate the distance between those points:

$r=\sqrt{(4-(-10))^2+(4-(-7))^2}$

$r=\sqrt{14^2+11^2}$

$r=\sqrt{196+121}=\sqrt{317}$

$\boxed{r\approx 17.80}$

Nonamiya [84]

Answer:

see below

Step-by-step explanation:

The following definitions apply:

if p, then q . . . . conditional statement

if q, then p . . . . converse

if ~p then ~q . . . inverse

if ~q then ~p . . . contrapositive

You have ...

p = "it is October 31"

q = "it is Halloween"

(a) The <em>converse</em> is ...

If it is Halloween, then it is October 31.

(b) The <em>inverse</em> is ...

If it is not October 31, then it is not Halloween.

(c) The <em>contrapositive</em> is ...

if it is not Halloween, then it is not October 31.
