A2 cm object is 10 cm from a convex lens that has a focal length of 6 cm. the image is 8 cm from the lens.
the height of the image, to the tenths place, is
cm.

So we want to know the height of the image, Hi, formed by the convex lens. Height of the object is H0=2 cm, distance of the object from the convex lens is D0= 10 cm, focal length of the lens is f= 6 cm and the distance of the image from the lens is Di= 8 cm. The formula for the magnification M of the convex lens is: M= Hi/H0=-(Di/D0). Now we solve the equation: Hi=-(Di/D0)*H0 and plug in the numbers: Hi=-(8/10)*2=-0.8*2=-1.6 cm. So the height of the image is Hi=-1.6 cm. The minus sign tells us the image is inverted.
