Hello there!
For questions like these, I always like to translate the figure in my head or on paper so I can get a visual of what is going on.
Take answer A, and translate the figure in your head 1 unit to the left, and then rotate it 180 degrees counterclockwise about the origin. This happens to be the correct answer so we don't have to investigate the others.
This means the answer is A.
Remember that when you move the figure one unit left, it becomes 1 unit away from the x-axis, so the figure must STAY that way during a rotation about the origin.
I really hope this helps!
Best wishes :)
Answer:
156.42
Step-by-step explanation:
If the ring is is 181.45 divide it 1st by 7.25 which is the percent then from the quotient you get there subtract it from the original price
Answer:
5 units to right and 23 units down
Step-by-step explanation:
The vertex of
is at
.
In order to find the vertex of function a(x), we convert the function a(x) to vertex form.
The general vertex form is
.
Here,
is the vertex.
![a(x)=x^{2} -10x+2\\ a(x)=(x-5)^{2}-25+2=(x-5)^{2}-23](https://tex.z-dn.net/?f=a%28x%29%3Dx%5E%7B2%7D%20-10x%2B2%5C%5C%20a%28x%29%3D%28x-5%29%5E%7B2%7D-25%2B2%3D%28x-5%29%5E%7B2%7D-23)
So, the vertex of the graph of a(x) is at
and the vertex of f(x) is at
.
Therefore, in order to translate
to
, we have to move the vertex of f(x) 5 units to right and then 23 units down.
