There were two versions of the exam.

\bigskip

Version A - Problem 1 involved 1000 meters of fencing.

\begin{enumerate}

\item (a) 69.6788 m (b) The radius of the circle should be zero.
\item (a) 0.06652 m (b) 5.0555$^\circ$
\item (a) There are infinitely many such functions.  One is $\dsps f(x)=\frac{x+4}{x-2}$

(b) $\dsps f^{-1} (x) = 2-\sqrt{x-3}$

\item 447.84 years after 2005

\end{enumerate}

\bigskip

Version B - Problem 1 involved 800 meters of fencing.

\begin{enumerate}

\item (a) 52.7311 m  (b) The radius of the circle should be zero.
\item (a) 0.11104 m (b) 16.8517$^\circ$
\item (a) There are infinitely many such functions.  One is
$\dsps f(x) = \frac{x+10}{x+4} $

(b) $\dsps f^{-1}(x) = 5 + \sqrt{7+x}$

\item 24.87 years after 1995
\end{enumerate}
