Answer:
-126
Step-by-step explanation:
For the binomial expression the coefficient of
term is given by
.
We have to find the coefficient of 6th term in the binomial expansion of
.
Hence n=9 and r=5
The coefficient of 6th term =
=
= -126
The answer is the option B: A'(3, -2), B'(3, -5), C'(2, -4).
The explanation is shown below:
1. You must apply the following rule of rotation when the figure is rotated 90° counterclockwise around the origin:
→
2. Then, as you can see, you must switch and
and multiply
by -1.
3. Keeping this on mind, you have that the vertices of the triangle A'B'C' are the following:
A(-2,-3)→A'(3,-2)
B(-5,-3)→B'(3,-5)
C(-4,-2)→C(2,-4)
4. Therefore, you can conclude that the answer is the option B.
