Please make sure to state the for- mula/equation that you use to earn full credit (b) (c) Show the series is convergent. Please indicate the name of test that you use and steps that you perform (d) How many terms are required to ensure that the sum is accurate to within 10-9? (d)

a) 0.055140908

b) 0000000975

c) 1 / < 1 ( series is converges)

d) n=6

Step-by-step explanation:

Find the attachment for step by step explanation

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
