Please help me answer these questions. I am very stuck on them.

001 10.0 points A convex spherical mirror forms a virtual im- age 0.44 times the size of the object. The object distance is 17.8 cm. Scale: 10 cm =II Find the magnitude of the radius of curva- ture of the mirror. Answer in units of cm. ______ _"'"l._______ A concave mirror has a focal length of 46 cm. What is the position of the resulting image if the image is inverted and 3 times smaller than the object? Answer in units of cm. A buttery at eye level is 25 cm in front of a plane mirror. You are behind the buttery, 50 cm from the mirror. What is the distance between your eye and the image of the buttery in the mirror? Answer in units of cm. An object is p = 47.3 cm in front of a concave mirror. Its real image height is 6 times larger than the object height. What is the radius of curvature of the mir- ror? Answer in units of cm.
