5. An object is 30.0 cm to the left of a convex lens with a focal length of +8.0 cm. Draw a ray diagram of the setup showing the location of the image. Calculate the distance of the image from the lens. Is the image upright or inverted?

Sorry, we don't do drawings, including ray diagrams, here. Your textbook should explain how it is done. If not there are plenty of web sites that do.

For the location of the image, Di, you can always use the equation
1/Do + 1/Di = 1/f,
with
Do = 30 and f = 8

The image should be real and inverted in this case
