[tex]\bf \qquad \textit{Amount for Exponential Growth}
\\\\
A=P(1 + r)^t\qquad
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\\
r=rate\to r\%\to \frac{r}{100}\\
t=\textit{elapsed time}\\
\end{cases}
\\\\\\
A(x)=19(2.046)^2\implies A(x)=19(1+\stackrel{r}{1.046})^2
\\\\\\
\cfrac{r}{100}=1.046\implies r=100\cdot 1.046\implies r=104.6\%[/tex]
