Answer:
The equation is x² + y² = 144.
Step-by-step explanation:
This works the same way as before.
You know that at the origin, it equals (0, 0). So, we have no need to insert values for h and k. Therefore, it will just be x² + y² = r².
R is your radius, and this is given as 12 units. So, r = 12. Therefore, r² = 144.
Your final equation is x² + y² = 144.
I think it might be A because she might have asked the student what they wanted but i hope it helps

Answer:
D. 4 real roots and 0 complex roots
Step-by-step explanation:
If I assume that the function you are saying is

There should be up to "4 roots," there can't be more or less than 4 total solutions. First, we need to check how many sign changes are there in this function. There are 3 positive real roots. Now lets check for negative roots.
There are is only 1 negative real root. Since we basically have 4 real roots, and the max is 4. There should be 4 real roots and 0 complex roots.
