Question 10 Compute the value of the improper integral. (If the integral diverges to oo, type oo; if it diverges to - co, type -oo; if it diverges for some other reason, type DNE.) OO 3 dx = 1 + 22 3 Use the value of the improper integral to determine whether or not the series 1 + n2 converges or n=1 diverges. Enter C if the series is convergent, D if the series is divergent, and ? if the Integral Test does not apply: Submit QuestionQuestion 11 We want to use the Comparison Test to determine if the series: 15 *= 1 K8 + 17 converges or diverges by comparing it with: OO K3 k =1 We can conclude that: O The Comparison Test is inconclusive in this situation. O The first series diverges by comparison with the second series. O The first series converges by comparison with the second series. Submit QuestionQuestion 12 We want to use the Alternating Series Test to determine if the series: E ( - 1) * K 4 k + 5 k =1 converges or diverges. We can conclude that: The series converges by the Alternating Series Test. O The series diverges by the Alternating Series Test. The Alternating Series Test does not apply because the terms of the series do not alternate. O The Alternating Series Test does not apply because the absolute values of the terms do not approach 0, and the series diverges by divergence test. O The Alternating Series Test does not apply because the absolute values of the terms are not decreasing, but the series does converge. Submit
