#### Answer

$-33cm$

#### Work Step by Step

We can use the values given on table 34-5 in equation 34-8 to find the radius of the mirror, $r$. $\frac{n_1}{p}+\frac{n_2}{i}=\frac{n_2-n_1}{r}$ solving for r, we obtain: $r=(\frac{n_1}{p}+\frac{n_2}{i})^{-1}*(n_2-n_1)$ $r=(\frac{1.0}{10cm}+\frac{1.5}{-13cm})^{-1}*(1.5-1.0)$ $r=-33cm$
