The sum of n terms of a geometric series is found using the following formula:
where a is the first term and r is the common ratio.
In your question, a = 6 and r = 1/3, so we have:
which simplifies to:
X = 3
5(3) - 2 = 13
3(3) + 4 = 13
The answer to this problem is 50
Answer:
b
Step-by-step explanation:
Answer:
10 units
Step-by-step explanation:
The difference between the points is ...
z2 -z1 = (11 -11i) -(3 -5i) = (11 -3) +(-11 -(-5))i = 8 -6i
The magnitude of that difference is ...
d = √(8² +(-6)²) = √(64 +36) = √100 = 10
The distance between z1 and z2 is 10 units.
