The coordinates of the image of point B after the triangle is rotated 270° about the origin is (4, 2)
<h3>How to determine the image of point B?</h3>
The complete question is added as an attachment
From the attached image, we have the following coordinate
B = (-2, 4)
When the triangle is rotated by 270 degrees, the rule of rotation is:
(x, y) ⇒ (y, -x)
For point B, we have:
B' = (4, 2)
Hence, the coordinates of the image of point B after the triangle is rotated 270° about the origin is (4, 2)

Answer:
P(A)=0.5
P(B)=0.5
Step-by-step explanation:
It's known that P(A and B) = P(A) * P(B) "When A and B are independent.
Now, suppose that P(A) = P(B)
then
P(A) * P(B) = P(A) * P(A) = (P(A))^2
finally
(P(A))^2 = 0.25
I think it is +a but not to sure
Answer:
Step-by-step explanation:
(2x-7y)(2x+7y)
2x(2x+7y)-7y(2x+7y)
4x^2+14xy-14xy-49y^2
4x^2-49y^2
(2x)^2-(7y)^2
