If am, bm, and cm satisfy the inequalities 0 < bm < cm < am , for all m, what can we say about the
[infinity][infinity]
(a)σam(b)σbm
m=1m=1
series if we know that the series
[infinity]
(c)σcm
m=1
is divergent but know nothing else about am and bm?
1. (a) diverges , (b) diverges
2. (a) diverge, (b) converges
3. (a) converges, (b) need not converge
4. (a) converges, (b) diverges
5. (a) need not diverge. {b) diverges
6. (a) diverges, (b) need not diverge

6. (A) divergent, (B) need not divergent

Step-by-step explanation:

using comparision test,  A is divergent since it is greater than a divergent series but we don't know if B is divergent since it is less than divergent series but we don't know if it is converget either.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
