This is College Physics Answers with Shaun Dychko. We are going to find the magnification of the mirror that's in example [25.9] and we are told that its image distance is 3.00 meters and the object distance is 27.3 centimeters, which I have written as 27.3 times 10 to the minus 2 meters. So we just have to divide these two, make it negative and that's our magnification of negative 11.0.
