4 0

Answer:

Look at your the second digit (tens digit), and if it is 5 and over, then you will round up to the next hundered. If it is 4 and under, you round it down to the previous one.

Step-by-step explanation:

Example:

136 - you will have to round to the previous hundred making it 130.

The 3 in 136 is under 4, so you round down.

161 - you will have to round up a hundred, so your answer will be 200.

The 6 is over 5, so you round up.

If [infinity] cn8n n = 0 is convergent, can we conclude that each of the following series is convergent? (a) [infinity] cn(−3)n

pashok25 [27]

Answer:

a) we know that this is convergent.

b) we know that this might not converge.

Step-by-step explanation:

Given the $\sum^\infty_{n=0}C_n8^n$ is convergent

Therefore,

(a) $\sum^\infty_{n=0}C_n(-3)^n$ The power series $\sum C_nx^n$ has radius of convergence at least as big as 8. So we definitely know it converges for all x satisfying -8<x≤8. In particular for x = -3
