Answer:
C) Reflection about the origin
Step-by-step explanation:
DE points to the right and slightly down. D'E' points to the left and slightly up. The segments are parallel, not perpendicular, so represent a rotation of 180°, not 90°. If the figure were subject only to translation, these segments would point in the same direction.
The transformation is a reflection about the origin (C). (This is equivalent to a rotation of 180°.)
<u>Answer</u>
Time taken to paint the fence by Marco and Jaylyn is 2.72 hours
Heading can be given to this is work per hour
<u>Explanation</u>
Macro 6 hours to paint fence by himself
Therefore his 1 hour work = 1/6
Jaylyn 5 hours to paint the same fence by herself
Therefore 1 hour work of Jaylyn = 1/5
Together 1 hour work = 1/6 + 1/5 = 11/30
Therefore time taken to paint the fence together by them = 30/11 = 2.72 hours
