Answer:
12.6 cm
Explanation:
We can use the mirror equation to find the distance of the image from the mirror:
[tex]\frac{1}{f}=\frac{1}{p}+\frac{1}{q}[/tex]
where here we have
f = 9.50 cm is the focal length
p = 39 cm is the distance of the object from the mirror
Solving the equation for q, we find:
[tex]\frac{1}{q}=\frac{1}{f}-\frac{1}{p}=\frac{1}{9.50 cm}-\frac{1}{39 cm}=0.080 cm^{-1}\\q = \frac{1}{0.080 cm}=12.6 cm[/tex]
