Answer:
See below.
Step-by-step explanation:
4.

5.

6.

1. The correct answer among the choices provided is the first option. It is a geometric sequence and the common ratio is 2.
2. Fifth term in the geometric sequence is 405. The pattern in this sequence is to triple the last term to get the next answer.
Just a little conversion (I recommend writing it out, so you can see the terms cancel out):
39 feet/minute x 1 yard/3 feet x 1 minute/60 seconds= .21667 yards per second

The center is at (0,0) so the equation will be like
x^2 + y^2 = r^2 where r = radius of the circle.
from the diagram you can see that r = 4
answer is x^2 + y^2 = 16
You have to make columns
342/38=9
