Let ∑k=1[infinity](−1)k+1ak be a convergent alternating series with terms that are nonincreasing in magnitude. Let Rn=S−Sn be the remainder in approximating the value of that series by the sum of its first n terms. Then Rn≤an+1. In other words, the magnitude of the remainder is less than or equal to the magnitude of the first neglected term. For the convergent alternating series ∑k=0[infinity] (−1)k (2k+1)4, evaluate the nth partial sum for n=2. Then find an upper bound for the error S−Sn in using the nth partial sum Sn to estimate the value of the series S.

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

5 + 8 +7 + 4 + 0 +1 = 25

step-by-step explanation:

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
