Question

Determine whether the sequence converges or diverges. If it converges, give the limit.
60, -10, 5/3, -5/18

a. Diverges
b. Converges; 11100
c. Converges; 72
d. Converges; 0

Answer 1

i might be able to help :)

Answer 2

Hi thanks :)

Answer 3

no prob

Answer 4

So. What do I need to do?

Answer 5

can you recognize what type of a series this is ?

Answer 6

Ummmmm....what are my options?

Answer 7

lol its geometric because 10/60= 0.167 =r
and 5/3 / 10 = 0.167 =r

Answer 8

the consecutive terms maintain a fixed ratio

Answer 9

so we can use the geometric series test. do you remember what that is ?

Answer 10

@girlfromafrica

Answer 11

are you here

Answer 12

???

Answer 13

Sorry, the answer is 0. Right? @tvartheman12

Answer 14

It converges.

Answer 15

yes, its convergent because the ratio is less than 1. the sum of this series is 72

Answer 16

(what grade you in btw)

Answer 17

Thank you! I'm a freshman.

Answer 18

kk me two and also remember limit=sum in a geometric series.

Answer 19

is this one of the other questions you have to answer A certain radioactive isotope has a half-life of 11 days. If one is to make a table showing the half-life decay of a sample of this isotope from 32 grams to 1 gram; list the time (in days, starting with t = 0) in the first column and the mass remaining (in grams) in the second column, which type of sequence is used in the first column and which type of sequence is used in the second column?

Answer 20

I don't know, but I need to go. My quiz needs to be submitted soon. Thank you so much for your help man!

Answer 21

no prob, are you in connections

Answer 22

Oh wait. No. My other question is: A certain radioactive isotope has a half-life of 15 days. If one is to make a table showing the half-life decay of a sample of this isotope from 32 grams to 1 gram; list the time (in days, starting with t = 0) in the first column and the mass remaining (in grams) in the second column, which type of sequence is used in the first column and which type of sequence is used in the second column?

Answer 23

lol kk ill help lol

Answer 24

Thanks! I'll be on again in a little while :)
