Answer: B
Picture 1 shows the reflection of ABC 180° clockwise about the origin. To draw A'B'C' we draw the line segments AO, BO, and CO and extend them such that O is the midpoint of line segments AA', BB', and CC' respectively.
Picture 2 shows the line y=-x (the yellow line.) This is the line containing all points of the form (x, -x), that is, this points contains (1, -1), (-2, 2) etc...
We see that point C' is already on this line, and we draw the reflections of points B and C with respect to this line, to find B'' and C'' with coordinates as shown in the figure.
Answer: RHOMBUS
Step-by-step explanation:
The name of a polygon that has four congruent sides with the angles measuring 60°, 120°, 60° and 120° is rhombus.
According to the properties of a rhombus, the opposite angles are equal and opposite sides are parallel.
However, the adjacent angles of rhombus are supplementary which means that they add up to 180°.
For example:
60° + 120° = 180°

Answer: There is probability that he will be asked a question in class during Week 7 is 64%.
Step-by-step explanation:
Since we have given that
Probability that question in class being asked during Week 1 = 1%
Probability that question in class being asked during Week 2 = 2%
Probability that question in class being asked during Week 3 = 4%
and so on.
So, we need to find the probability that question being asked in class during week 7.
Since it forms geometric series:
1%, 2%, 4%, ........
So, we need to find the 7 th term:
![a_n=ar^{n-1}\\\\a_7=ar^{7-1}\\\\a_7=1(2)^6\\\\a_7=64\%](https://tex.z-dn.net/?f=a_n%3Dar%5E%7Bn-1%7D%5C%5C%5C%5Ca_7%3Dar%5E%7B7-1%7D%5C%5C%5C%5Ca_7%3D1%282%29%5E6%5C%5C%5C%5Ca_7%3D64%5C%25)
Hence, there is probability that he will be asked a question in class during Week 7 is 64%.
