Answer:
∑ₙ₌₁⁸ (3n − 9)
Step-by-step explanation:
This is an arithmetic series where the first term is -6 and the common difference is 3. The nth term can be written as:
aₙ = a₁ + d (n − 1)
aₙ = -6 + 3 (n − 1)
There are 8 terms in this series, so the sum is:
∑ₙ₌₁⁸ [-6 + 3 (n − 1)]
Simplified:
∑ₙ₌₁⁸ (3n − 9)
Answer:
Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

Answer:
Step-by-step explanation:
-----------
5/7 can be written as 0.714285
-----
7/9 can be written as 0.777
∴ An irrational number between 5/7 and 7/9 is 0.72010010001.....
or u ca write other numbers also like
0.73010203.....
0.74090080007.....
Answer:
A. AAS
Step-by-step explanation:
The vertical angles are congruent, the adjacent marked angles are congruent, and the marked sides on the far side of both angles are congruent. This geometry matches the conditions for Angle-Angle-Side (AAS) congruence.
So.. if you notice the picture below.. .the length is that much
thus
take the derivative of A, zero it out, and then check the critica points for any maxima by using the first-derivative test
