**Anonymous**, Friday, August 22, 2008 at 7:21pmRepeated question with correct information in the question:

To find the image length, of a 4-foot-tall object in a spherical mirror with a focal length of 2 feet, L=4(2/o-2)^2 can be used, where o is the distance, in feet, of the object from the mirror. What is the image length of the object when it is 1.5 feet away from the mirror?

=4 (2/3 -2)^2

= 4 (-2/3)^2 = 4* 4/9 = 16/9
