Answer:
its c ok
Step-by-step explanation:
We will study the convergence of the series

For

the series has constant general term which is divergent.
For

the series diverges since its general term goes to infinity as n goes to infinity.
For

, the series converges since it is equivalent to the Riemann series.
Answer:
it take 41 minutes to 14 people to paint 14 walls
Step-by-step explanation:
we know that
It takes 41 minutes for 9 people to paint 9 walls.
Divide the number of people by the number of walls

so
it take 41 minutes to one people to paint one wall
therefore
it take 41 minutes to 14 people to paint 14 walls
THe value of 9 in the given number 8.90
Since this is a decimal value, let's determine the value of each number first
=> 8 is the whole number thus, its value is ones.
=> Since 9 is next to the decimal point its values is tenths.
Thus the value of 9 is tenths.
