Hello! I have difficulty with basic algebraic equations could you please break down every part? A convex mirror in an amusement park has a radius of curvature of $3\mathrm{.}00$ m $.$ A man stands in front of the mirror so that his image is half as tall as his actual height. At what distance must the man focus his eyes in order to see his image?$2\mathrm{.}25$ m$3\mathrm{.}00$ m$4\mathrm{.}50$ m$5\mathrm{.}00$ m$6\mathrm{.}75$ m
