Answer:
The leading coefficient in the polynomial 10x2 + 3x - 5 is 10.
Step-by-step explanation:
To find the leading coefficient of the polynomial function, we must first locate the leading term. In a polynomial function, the leading term is the term containing the highest power of x. In this polynomial function, the leading term is 10x2. The leading coefficient of a polynomial function is the coefficient of the leading term, and so the leading coefficient of this polynomial function is 10.
First find the hourly rate by dividing $187 by 11 hours. That yields $11 per hour. Now multiple the $11/hour rate by 8 hours of work resulting in $88.
Given:
The table for a geometric sequence.
To find:
The formula for the given sequence and the 10th term of the sequence.
Solution:
In the given geometric sequence, the first term is 1120 and the common ratio is:
The nth term of a geometric sequence is:
Where a is the first term and r is the common ratio.
Putting 
, we get
Therefore, the required formula for the given sequence is .
We need to find the 10th term of the given sequence. So, substituting 
in the above formula.
Therefore, the 10th term of the given sequence is 2.1875.
Answer:
the only one that is a function is B
Step-by-step explanation:
the rest of them have repeating inputs which makes them no functions
