Find the length of the line from A to C, which would be the radius using the distance formula:
Distance = √(-5 +1)^2 + 1+2)^2)
Distance = √(4^2 + 3^2)
Distance = √25
Distance = 5
The equation of a circle is written as (x-h)^2 + (y-k)^2 = r^2, where h and k is the center point X and y values and r is the radius.
The center of the circle is located at A ( -1,-2) and the radius is 5.
Replace h, k and r with those values:
(x - (-1))^2 + (y- (-2))^2 = 5^2
Simplify to get:
(x+1)^2 + (y+2)^2 = 25
Answer:
contrapositive
Step-by-step explanation:
The <u>converse</u> statement would be ...
b ⇒ a
The <u>contrapositive</u> swaps the parts and negates them both:
¬b ⇒ ¬a . . . . . matches your given statement
The <u>inverse</u> negates both parts:
¬a ⇒ ¬b
A <u>contradiction</u> arises when the implication is false: a is true and b is false.
