Best ResponseYou've already chosen the best response.0is it \(\overline{.36}\) ?

Best ResponseYou've already chosen the best response.0I have the formula \[S _{n}=\frac{ a _{1}a_{1}r ^{n} }{ 1r }\] If that helps.

Best ResponseYou've already chosen the best response.0ok one simple method is to call \(x=\overline{.36}\) so \(100x=36\overline{.36}\) subtract and get \(100xx=36\) so \[99x=36\] and therefore \[x=\frac{36}{99}=\frac{4}{11}\] but that might not be what you want

Best ResponseYou've already chosen the best response.0if you want to use the formula you wrote above, then since you are summing an infinite geometric series omit the \(a_1r^n\) part and go with \[S=\frac{a_1}{1r}\]

Best ResponseYou've already chosen the best response.0Oh. I think I copied the formula down incorrectly...

Best ResponseYou've already chosen the best response.0Cuz I was looking through my notes and wondering how I got the answers with the a1r^n part

Best ResponseYou've already chosen the best response.0yeah since \(r<1\) you have \(\lim_{n\to \infty}r^n=0\)

Best ResponseYou've already chosen the best response.0in this case you can use \[a=\frac{36}{100}\] and \[r=\frac{1}{100}\]

Best ResponseYou've already chosen the best response.0For reference, though, does that formula equal\[S_{n}= \frac{ a_{1}(1r ^{n)} }{ 1r }\]

Best ResponseYou've already chosen the best response.0you get \[S=\overline{.36}=\frac{\frac{36}{100}}{1\frac{1}{100}}\] \[=\frac{\frac{36}{100}}{\frac{99}{100}}\] \[=\frac{36}{99}\] etc
