Locus: centre (1,0) radius 4 ? (2 Viewers)

[jamesfirst]

Right ?

 

[someth1ng]

Yes.

 

[sinsolja]

Yep , thats what i got.

 

[jamesfirst]

Yeahya

 

[_deloso]

How do you do this question?

 

[amour]

Right ?

FML I GOT RADIUS 8 and werid center. i think i did completing the square wrong and effed my algebraa

 

[mitchh81]

 

[amour]

did the sameeeee
took me a while to actually understand wat the q was asking tho

 

[jamesfirst]

this is what I did too.


lolz

 

[damo_g]

Ye that's the answer i got. Feels good man.

 

[mitchh81]

but then i got x^2 + 2x +2 +y^2 +x^2 -6x +9 +y^2 =40

 

[jamesfirst]

but then i got x^2 + 2x +2 +y^2 +x^2 -6x +9 +y^2 =40

Don't you know how to expand man ???

 

[A_Machiavellian]

centre (1,0) radius 19^(1/2)

derp

 

[friend177]

OMFG I was up to that stage and they said pens down times up I didn't find the answer but I did all that shit ah well probs get 2/3

 

[jamesfirst]

centre (1,0) radius 19^(1/2)

derp

WRONG. lolz

 

[mitchh81]

Don't you know how to expand man ???

damm just realized my
mistake

 

[KGZ9]

centre (1,0) radius 19^(1/2)

derp

DAMMIT! that's what i got

 

[_deloso]

I did that. What do U after to find centre and radius?

 

[MetalTheory]

OMFG I was up to that stage and they said pens down times up I didn't find the answer but I did all that shit ah well probs get 2/3

You and me both, man. I just finished expanding when they announced "pens down". Grrrr.

 

[SXCBEAST]

yeah centre (1,0) radius 4
