Answer:

Step-by-step explanation:
we have the sequence

we know that
In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant and this term is called a common difference
Let

we know that
----> 
----> 
The common difference is 2
This is an arithmetic sequence
The general formula for an arithmetic sequence is

where
d is the common difference
n is the number of terms
substitute the given values



Answer:
1. .43 m/s or 26.08 meters per min
5. The total displacement is 0
Step-by-step explanation:
The number of positive zeros is either 2 or 0. The number of negative zeros is either 2 or 0
<h3>How to determine the true statement?</h3>
The polynomial function is given as:

The degree of the polynomial function is:
Degree = 4
Divide by 2
Degree/2 = 2
This means that:
The number of positive zeros and negative zeros can be 2
The difference between these zeros count is:
Difference= 2 - 2 = 0
The number of positive zeros and negative zeros can also be 0
Hence, the number of positive zeros is either 2 or 0. The number of negative zeros is either 2 or 0
