2/10ths of an hour. You do 12/60 and get 0.2
Answer:
-2n²
Step-by-step explanation:
Using the image attached:
We see that the second differences (blue ones) are all equal so we conclude that this is a quadratic sequence.
The quadratic sequence has the form:

To find the value of a we just divide second difference ( -4 ) by 2:
Now we have:
Substitute
and
into the equation above:
Since
= -2 and
= -8 , after simplification we have:
The solution of this system is:
The general term is :

Answer:
fully simplified answer: x^2-2x+8

Answer:
Hiiiii
I'm okay, how about you?
thanks for the free points! :)
To find the average: the sum of the values/number of values
=250+310+275+195/4
=257.5
