If ABCD is dilated by a scale factor of 2 about point E, which of the following is true about E'F'? В.
C
m
A
D
OE'F' is perpendicular to EF
OE'F' is parallel to EF
OE'F' intersects with point B'.
O E'F' passes throug[mhe center of dilation.

Given:

ABCD is dilated by a scale factor of 2 about point E.

To find:

The correct statement about the line segment E'E'.

Solution:

The center of dilation E lies on the line segment E'F' and the dilation factor is 2.

Since the center of dilation E is one end point EF, therefore E and E' represents the same point.

It means, E'F' passes through the center of dilation.

Hence the correct option is D.

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
