A colony of bacteria triples in link every 10 minutes. It's length is now 1 mm. How long will be in 40 minutes
Nuetrik [128]
If the bacteria is tripling every 10 minutes, that means the "rate of increase" on that period is 200%, so if say the current amount is "c", 200% of "c" is just 2c, so c + 2c is 3c, a tripled amount.

\bf \textit{Periodic Exponential Growth}\\\\&#10;A=I(1 + r)^{\frac{t}{p}}\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;I=\textit{initial amount}\to &1\\&#10;r=rate\to 2\%\to \frac{200}{100}\to &2.00\\&#10;t=\textit{elapsed time}\to &40\\&#10;p=period\to &10&#10;\end{cases}&#10;\\\\\\&#10;A=1(1 + 2)^{\frac{40}{10}}
