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.
4/9
Multiply each answer choice by 3/4 or 1/3 and they will all be wrong except for 4/9.
3 x 4 = 1/3
so 4/9
to multiply-----
(2y-1)(2y+1)
2y(2y+1)-1(2y+1)
4y^2+2y-2y-1
=4y^2-1
60 hundreds means 6000 = 6 thousands;
So, 10 · x = 6000;
x = 600;
600 means 6 hundreds;
Finally, 10 times as many as 6 hundreds is 60 hundreds or 6 thousands.
