Answer:
c) The series diverges. There is no sum.
Step-by-step explanation:
A geometric series is a series of the form:
,
Where:
- First term of the series, dimensionless.
- Common ratio, dimensionless.
A geometric series converges only if . As , the geometric series diverges. Hence, the right answer is C.
Answer:
Hence, the number of ways of doing so is:
780 ways.
Step-by-step explanation:
We know that if we have to choose r items out of a total of 'n' items then the number of ways of doing so is calculated by the formula of combination as:
which is given by:
Here we have to chose 2 books out of a shelf of 40 books.
i.e. we have: n=40 and r=2
Hence, the number of ways of doing so is:
Hence, the answer is:
780
Answer:
The value of x in given question will be
Step-by-step explanation:
Given data:
7x-c=k
Now,
7x-c=K
7x=K+c
Therefore,
The value of x in given question will be : k+c/7
