All of these sets meet the requirements of the triangle inequality. The sum of any two numbers in the set is greater than the third one. (You really only need to check that the sum of the smallest two is greater than the largest.)
It can help to resolve the numbers that are only indicated as to value.
√13 ≈ 3.606
2√10 ≈ 6.325
_____
Your comparisons can be ...
2 + 3 = 5 > 3.606 . . . is a triangle
5 + 5 = 10 > 6.325 . . . . . . is a triangle
5 + 12 = 17 > 15 . . . . . . . . is a triangle
Answer:
The average slope is 8.
Step-by-step explanation:
Let <em>f</em> be defined on the closed interval [a, b]. The average slope of <em>f </em>between a and b is the quotient
average slope = 
To find the average slope of the function
on the interval [-1, 3] you have to evaluate your function in the interval and then divide by the interval.
So,

The average slope is

Answer:
C 
Step-by-step explanation:
Consider the series

The nth term of series is 
The bottom index tells you that n starts changing from 3, so

Thus, the sum of all terms is
