(x-1)^2 + (y-5)^2 > 9
ganeshie8
  • ganeshie8
first graph the corresponding equality
ganeshie8
  • ganeshie8
(x-1)^2 + (y-5)^2 = 9 wat kind of curve this equation represents ?

@ganeshie8 i honestly i have no idea graphs are one thing i have no idea about i never understood them
ganeshie8
  • ganeshie8
its okay :) graphs are tricky.... they take some time for us to get comfortable wid :)
ganeshie8
  • ganeshie8
just remember this blindly, \((x-h)^2 + (y-k)^2 = r^2\) represents a circle

i hate graphs :(

and okay ill try!

lol im ex-hater too ;)

our present equation \((x-1)^2 + (y-5)^2 = 9 \) first glanxe, it looks like the circle equation, i was familiar wid. so i realize that its a circle, with center at (1, 5) and radius of 3
ganeshie8
  • ganeshie8
having that knowledge, i draw a coordinate plane, and draw the circle at center (1, 5)

ganeshie8
  • ganeshie8
over there i simply draw a circle wid radius 3
ErinWeeks
  • ErinWeeks
ok i dont know how to do radius but what you did so far makes sense
ganeshie8

ok, im not good at drawing roung circles either lol. it should look something like that. next lets work the inequality
ErinWeeks
  • ErinWeeks
okay .. i understand most people arent the best at drawing your doesnt look to bad though lol
ganeshie8
  • ganeshie8
aww thnks :) (x-1)^2 + (y-5)^2 > 9 since we have > symbol here, that means the distance must be greater than this radius occipied by this circle. that simply means, shade the region outside the circle.

so we got a sun, wid radius 3
ErinWeeks
  • ErinWeeks
okay lol ... its going to be this than?

everything outside that region is represented by our inequality :)
ErinWeeks
  • ErinWeeks
okay i got the right answer(:?
ganeshie8
  • ganeshie8
Yes !
ErinWeeks
  • ErinWeeks
thank you ... Your one person that makes sense to me lol!
ganeshie8
  • ganeshie8
one thing, since we dont have >= here, we oly have > so the sun must be dotted... i dint make the sun dotted, cuz my fingers are bit shaking when i drew the circle... :/
ganeshie8
  • ganeshie8
np :) you're wlcme !!
ganeshie8

  • ganeshie8
it should look like that for >, dotted on the boundary. btw, you picked the right option :)
