Answer:
(-2, 11/2)
Step-by-step explanation:
use the mid-point formula!
((x1+x2)/2, (y1+y2)/2)
((-1+-3)/2, (-1+12)/2)
(-2, 11/2)
Let the number of contestants is n and the prizes is r
the number of ways is npr = 335p3 = 37259370 ways
3 is the greatest common denominator
The function that best defines this arithmetic sequence is:
<h3>What is an arithmetic sequence?</h3>
- In an <em>arithmetic sequence,</em> the <u>difference between consecutive terms is always the same</u>, called common difference d.
The recursive function that defines the sequence is:


- In which
is the first term.
In this problem, the sequence is: {9, 5, 1, -3}
- Each term is the previous term subtracted by 4, hence
.
- The first term is 9, hence
.
Hence, the function is:
