Question

Circle O is defined by the equation x2 + (y - 2)2 = 25. Plot the center of Circle O and type in the coordinates of one point with integral values that lies on Circle O.

Answer 1

so th radius would be 5

Answer 2

the circle equation of center(x_1,y_1) and raduis r

\(\large (x-x_1)^2+(y-y_1)^2=r^2\)

Answer 3

yes correct :) what about center?

Answer 4

I know the y would 4 right?? and x i dont know.

Answer 5

u can write the equation like this
no y \(\neq \) 4 , check again
\(\large (x-0)^2+(y-2)^2=r^2\)

Answer 6

-4??

Answer 7

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

how did u get 4 ?

Answer 8

-2 ^2 equals 4

Answer 9

but it should not be -2^2
it only be 2 , as the example before

Answer 10

oh i see,

Answer 11

so what is the center and raduis again ?

Answer 12

0,2 and the radius 5

Answer 13

correct :)
and draw the circle

Answer 14

okay! thanks that was helpful, really helpful!!

Answer 15

i don't quite get this!

Answer 16

hahah sorry :(

Answer 17

but we dint finish the first one yet :o

Answer 18

oh, i thought we did xD continue sorry.

Answer 19

lol sorry nvmits done :P

Answer 20

ok the second one
m<SOT= 2 * m<SRT

Answer 21

yeah,

Answer 22

find , m <SRT
:o
m <SRT=m<SOT / 2=68/2

Answer 23

sorry im so out of it, i have slept a total of 5 hrs in the last 3days and i'm trying really hard to get these answers so i can rest.

Answer 24

how old are u ?

Answer 25

15

Answer 26

ohh sleep more xD

nw for the question
m <SRT=m<SOT / 2=68/2

so
m<SRT=68/2=34

Answer 27

srt = 34?

Answer 28

yep
