[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}
\\\\\\
\boxed{A=P(1 + r)^t~~\implies ~~a(x)=(2.046)^x}
\\\\\\
1+r=2.046\implies r=2.046-1\implies r=1.046
\\\\\\
r\%=1.046\cdot 100\implies r=\stackrel{\%}{104.6}[/tex]
