Answer:
9.9
Step-by-step explanation:
Not just any geometric series, but an infinite one. The rare taming of infinity.
Since the ratio r=2/5 is strictly between -1 and 1 the infinite geometric series converges. The first term is also a=2/5 so the sum is
Answer: 2/3
That formula isn't too hard to derive. We have
Answer: 2a^3-a^2+2a-3
Step-by-step explanation:
(2a^2+a+3) (a-1)
2a^3-2a^2+a^2-a+3a-3
2a^3-a^2+2a-3
