The ray diagram shows a vase that is placed beyond the center of curvature of a concave mirror.
2 answers:
Answer:
The property of concave mirror says that the line which is coming beyond center of curvature will come back to focus and parallel to the focus
And the image will be between center of curvature and focus. And arrow shows the image the way it will appear.
Please look at the attachment to see the object
Therefore, option D is correct that is it will be smaller than the vase and inverted.

The plane's actual velocity is the vector sum of the two velocities. It is
The magnitude of the actual velocity is
v = √(121.1615² + 306.0473²) = 329.158 km/h
The angle that the velocity makes north of east is
tan⁻¹ (306.04733/121.1615) = 21.6°
Answer:
The actual velocity is 329.2 km/h at 21.6° north of east.
