Answer: D. 36, 108
Step-by-step explanation:
In the geometric series the ratio of two consecutive term is constant and this ratio is called the common ratio,
Let n be the common ratio of the given series,
Then the GP will be,
12, 12×n, 12×n×n, 324,
Again by the definition of Geometric series,
Thus, the required series is,
12, 12×3, 36×3, 324
= 12, 36, 108, 324
⇒ Option D is correct.
Answer:
d= 2
Step-by-step explanation:
To find the common difference, take the second term and subtract the first
-2 - (-4)
-2+4 = 2
We add 2 each time
Lets check
Take the third term and subtract the second
0- -2
0+2 =2
The common difference is 2
On a graph, the point moves down 9 points and to the right by 2

Answer: ;
Step-by-step explanation:
I have never done a problem like this, so this is my first time attempting it.
The standard form for the equation of a circle is:
Begin by grouping the 'x' terms and 'y' terms:
Complete the square for the second polynomial:
Do the exact same process with the other polynomial:
Complete the square:
Bring the 121 to the other side to get:
The above expression is the equation of our circle in standard form. It is centered at the coordinates (7, -2) and has a radius of 11 units. The area of a circle if given by:
