Step-by-step explanation:
For 8z = 40, z= 5. z is 5 and only 5
For 8z >= 40, z >=5, z can be a lot of numbers ranging from 5 upwards. The boundary for 8z >= 40 is 5 and 5 up
Step-by-step explanation:
a function that describes a set of points in Cartesian space by mapping each x-coordinate to a y-coordinate, then a circle cannot be described by a function because it fails what is known in High School as the vertical line test. A function, by definition, has a unique output for every input.
Given:
The sequence is:

To find:
The explicit formula for the given sequence and then find the 16th term.
Solution:
We have,

The ratio between two consecutive terms are:



The given sequence has a common ratio. So, the given sequence is a geometric sequence with first term 6 and common ratio
.
The explicit formula of a geometric sequence is:

Where, a is the first term and r is the common ratio.
Putting
in the above formula, we get

We need to find the 16th term. So, put
in the above formula.




Therefore, the explicit formula for the given sequence is
and 16th term of the given sequence is
.
