Easy peasy
a circle centered at the origin is form
x^2+y^2=r^2
r=radius
point (5,-12) is on it
sub to find r^2
(x,y)
(5,-12)
(5)^2+(-12)^2=r^2
25+144=r^2
169=r^2
sqrt both sides
13=r
the radius is 13

Answer: 11.008
Step-by-step explanation: The 3 goes into the other 3 1 time. 3-3 is 0. Bring down the other 3. 3 goes into 3 one time. 3-3 is zero. Bring down the zero. 3 goes into 0, 0 times. 0-0 is 0. Bring down the two. 3 goes into 2 zero times. 2-0 is 2. Bring down 4. 3 goes into my 24 8 times.
Answer:
y = -11.5
Step-by-step explanation:
2y = 18-41
Combine like terms
2y = -23
Divide each side by 2
2y/2 = -23/2
y = -11.5
