    Answer:

    The image height is 3.0 cm

    Explanation:

    Given;

    object distance, d_o = 15.0 cm

    image distance, d_i = 5.0 cm

    height of the object, h_o = 9.0 cm

    height of the image, h_i = ?

    Apply lens equation;

    \frac{h_i}{h_o} = -\frac{d_i}{d_o}\\\\ h_i = h_o(-\frac{d_i}{d_o})\\\\h_i = -9(\frac{5}{15} )\\\\h_i = -3 \ cm

    Therefore, the image height is 3.0 cm. The negative values for image height indicate that the image is an inverted image.
