Consider the following series. 1 5 1 10 1 15 1 20 1 25 Determine whether the series is convergent or divergent. Justify your ans

wer. Converges; the series is a constant multiple geometric series. Converges; the limit of the terms, an, is 0 as n goes to infinity. Diverges; the limit of the terms, an, is not 0 as n goes to infinity. Diverges; the series is a constant multiple of the harmonic series.

Answer:

The series Diverges ; The series is a constant multiple of harmonic series

Step-by-step explanation:

The series :

1/5 + 1/10 + 1/15 + 1/20 + 1/25

The series  can be expressed as :

a1 = 1 / 5*1

a2 = 1 / 5*2

a3 = 1 / 5*3

a4 = 1 / 5*4

a5 = 1 / 5*5

hence we can write a_{n} as ;  a

attached below is the remaining part of the solution

if k is a constant, what is the value of such that the polynomial 2x3+x2+kx+18 is divisible to x+3. Show your complete work
Harman [31]

Remark

What value of k will make the entire polynomial = 0 when k is meant to be a factor? In brief, solve the polynomial when f(-3) is substituted into the right hand side.

f(x) = 2x3+x2+kx+18

f(-3) = 2x3+x2+kx+18

f(-3) = 2(-3)^3 + (-3)^2 - 3k + 18 = 0

-54 + 9 - 3k + 18 = 0

-54 + 9 + 18 - 3k = 0

-27 - 3k = 0

- 3k = 27

k = 27/ - 3 = - 9

Answer

k = -9

Check

2x^3 + x^2 - 9x + 18 = 0

2(-3)^3 + (-3^2) - 9(-3) + 18 = 0

-54 + 9 + 27 + 18 = 0   Just as it should be.
