Answer:
523 to the nearest ten is 520
Given:
The geometric sequence is:

To find:
The 9th term of the given geometric sequence.
Solution:
We have,

Here, the first term is:

The common ratio is:




The nth term of a geometric sequence is:

Where, a is the first term and r is the common ratio.
Substitute
to find the 9th term.




Therefore, the 9th term of the given geometric sequence is 5103.
Answer:
(1, -1), (1, -2), (2, -3), (2, -4)
NO
Step-by-step explanation:
✔️Each ordered pair is written as (input, output).
Thus, we would have the following:
(1, -1), (1, -2), (2, -3), (2, -4)
✔️This cannot be a function because every input value do not have exactly one output value related to it. A function should not have an input value related to more than one output value.
So, the answer is NO. It is not a function.
