Question

Identify the center and the radius of the circle with equation x2 + (y - 5)2= 9


center (0, 5) and radius = 3

center (0, 5) and radius = 81

center (0, -5) and radius = 81

center (0, -5) and radius = 3

Answer 1

use equation of the circle again :)

Answer 2

its
blah+blah=r^2

Answer 3

if your

r^2=9 then r must be?

Answer 4

3

Answer 5

x2 + (y - 5)2= 9 is already in the equation

Answer 6

A or D :D

Answer 7

\(\bf {\color{blue}{ 9\implies 3^2}}
\\ \quad \\ \quad \\

x^2 + (y - 5)2= 9\implies (x-0)^2 + (y - 5)2= 3^2\) what do you think?

Answer 8

+5 according to equation

Answer 9

woops, darn. typo \(\bf {\color{blue}{ 9\implies 3^2}}
\\ \quad \\ \quad \\

x^2 + (y - 5)2= 9\implies (x-0)^2 + (y - 5)^2= 3^2\)

Answer 10

\(\bf x^2 + (y - 5)^2= 9\implies (x-0)^2 + (y - 5)^2= 3^2\) any ideas?

Answer 11

It's A I think.

Answer 12

\(\bf (x-{\color{red}{ 0}})^2 + (y - {\color{blue}{ 5}})^2= 3^2\Leftarrow center=(0,5)\qquad radius=3\)
yeap

Answer 13

ah thank you!! uvu
