    I see more of a question in the title page, I hope this is all of the question.

    An object is placed 30 cm to the left of a concave spherical mirror of radius 10 cm.

    (a) What is the focal length of this mirror?

    Focal lengths of concave spherical mirrors are half the radius of curvature

    f = 5 cm

    I hope this helps.
