Answer:B 8
Step-by-step explanation: 6 ÷ 3/4 =8
Answer: The correct option is C .The Ratio Test says that the series converges conditionally.
Step-by-step explanation:
Ratio test is used for testing convergence or divergence in series.
Iet consider a positive series
Summation a subscript n. £an
Let £an > 0.
Consider
Lim as n tends to infinity, 'a' subscript n+1 divided by 'a' subscript n = L
If L < 1 the series converges
If L >1 the series diverges
If L= 1 No conclusion.
The correct option is C because the series converges conditionally if L <1
X^2 + 30x + 21
= ( x + 15)^2 - 225 + 21
= (x + 15)^2 - 204
Its D minimum at -204
