Answer:
D' = ( 1 , -1 )
Step-by-step explanation:
2 times 1/2 = 1
-2 times 1/2 = -1
hope this helps ^^
For this case we have to:
The circumference or perimeter of a circle is given by:

where d is the diameter of the circle.
Substituting the given value of c,
, we have:


Therefore, the diameter of the circle is 6m.
Answer:
Option C
If we draw RU and RT we see the radii are perpendicular to the tangents, so TRU and TZU are supplementary. Since TZU=XZY=15 degrees, TRU=180-15=165 degrees. So the other side is 360-165=195 degrees as is the measure of arc TSU
Answer: 195 degrees
