Image characteristics for Case 3: Object distance d0=R. Choose the ones that apply:

Case 1: Object distance d0= infinity. The figure below shows light rays coming from an object located at infinity, in front of a convex lens. Extend the 9 incident rays to the lens, and draw the transmitted rays in the correct direction. Use the figure, DO NOT substitute it with any other figure. Use the line to trace the 9 rays. Don't forget to place the arrow on each transmitted beam. Label each ray with its corresponding name: parallel ray, central ray, and focal ray. Image characteristics for Case 1: Object distance d0= infinity. Select those that apply: a) Reduced b) Real c) Erect d) Inverted e) Equal size f) Increased g) Virtual h) No image is formed

Please explain everything in detail and step by step please

1.)The diverging lens of the figure produces an image of an object to the left of the lens and 5.00 cm away from the center of the lens. The refracting index of the lens is 1.50. The magnitude of the focal length of the lens is 12.0 cm and the radius of curvature R1 is 15.0 cm. A.) Calculate the radius of curvature R2 of the lens. Show your work. B.) Fill in the following table with the focal length of the lens, the distance of the image  and the distance of the object (you have to calculate that) with the correct signs!  f s s'       C.) Is the object to the left or to the right of the lens? (Select one.) D.) Is the image formed by the lens upright or inverted compared to the object? (Select one.)
