is r the given?

yes r is 8 its based off the formula x^2+y^2=8

i think its the last one r^2=64 r=8

x^2+y^2=8 ==> r^2=8

no but when you are converting to a polar equation \[r=\sqrt{x^2+y^2}\]
 one year ago

galacticwavesXX Group TitleBest ResponseYou've already chosen the best response.1
therefore \[r^2=x^2+y^2\]
 one year ago

galacticwavesXX Group TitleBest ResponseYou've already chosen the best response.1
so you are replacing the \[x^2+y^2 \]
 one year ago

galacticwavesXX Group TitleBest ResponseYou've already chosen the best response.1
with \[r^2\]
 one year ago

galacticwavesXX Group TitleBest ResponseYou've already chosen the best response.1
yes you are converting from a rectangular equation to a polar equation
 one year ago

galacticwavesXX Group TitleBest ResponseYou've already chosen the best response.1
that's what is stated in the question to do
 one year ago

galacticwavesXX Group TitleBest ResponseYou've already chosen the best response.1
but if you teacher wants r itself then r is \[r=2\sqrt{2}\]
 one year ago

galacticwavesXX Group TitleBest ResponseYou've already chosen the best response.1
r cant be 4 because you have are taking the root of 8 not halving it
