Answer:
C
Step-by-step explanation:
A geometric series will only converge if - 1 < r < 1
sum to infinity =
The nth term formula for a geometric series is
= a
where a is the first term and r the common ratio
The only summation with - 1 < r < 1 is C where r = - 0.2
Answer:
B

A straight line equals to 180 degrees. The example shown is a linear pair!
No because (-2, -5) is negative and the y coordinate needs to be positive.
