If is the first number in the progression, and
is the common ratio between consecutive terms, then the first four terms in the progression are
We want to have
In the second equation, we have
and in the first, we have
Substituting this into the second equation, we find
So now we have
Then the four numbers are
Answer:
Step-by-step explanation:
Triangle P is mapped onto Q so P is the initial triangle that will transformed.
We can rotate counterclockwise 90° but we cannot do it about the origin (0,0) because the red point (5, 1) will end up at ( -1, 5) .
We see that the point (5, 1) ends up at ( -2, 4) so the center of rotation is lower than the origin.
The transformation is rotation of 90° about the point (0,-1)
