Step-by-step explanation:
The numerical expression is:
(36 + 14) / (2 * 5).
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 :
It’s 21.99
Use c=2pi*radius
Diameter divided by 2 = radius
A ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
