Suppose that the functions $$ q $$ and $$ r $$ are defined as follows. $$ \begin{array}{l}q(x)=x^{2}+9 \ r(x)=\sqrt{x+8}\end{array} $$ Find the following. $$ \begin{array}{l}(r \circ q)(8)= \ (q \circ r)(8)=\square\end{array} $$

1. Calculate $$(r \circ q)(8)$$:
   - Compute $$ q(8) $$:
     $$
     q(8) = 8^2 + 9 = 64 + 9 = 73
     $$
   - Then compute $$ r(q(8)) $$:
     $$
     r(73) = \sqrt{73 + 8} = \sqrt{81} = 9
     $$
   Thus, $$(r \circ q)(8) = 9$$.

2. Calculate $$(q \circ r)(8)$$:
   - Compute $$ r(8) $$:
     $$
     r(8) = \sqrt{8 + 8} = \sqrt{16} = 4
     $$
   - Then compute $$ q(r(8)) $$:
     $$
     q(4) = 4^2 + 9 = 16+9 = 25
     $$
   Thus, $$(q \circ r)(8) = 25$$.
$$(r \circ q)(8) = 9$$ and $$(q \circ r)(8) = 25$$.
