Answer:
Sectionalism

Answer:
From the first generation = 2 ancestors.
From the second generation = 4 ancestors or (2)^2 ancestors.
From the third generation = 8 ancestors or (2)^3 ancestors.
We can infer from the given data, each consecutive generation possesses twice the number of members.
The sum will be:
2 + 4 + 8 + 16 + ... + (2)^39
To evaluate the amount of ancestors, let's employ the formula for the summation of a geometric sequence.
(Geometric sequence shows the sequence of numbers that varies by a specific factor. This factor is specifically known as a ratio).
Formula for Geometric sequence:
S = (a1) × 1 - (r)^n
--------------------------
1 - r
Take:
S -> sum
a1 -> first member of a sequence
r -> ratio
n -> number of elements
In this question, our:
a1 = 2; r = 2; and n = 39
S = (2) × 1 - (2)^39
-------------------------
1 - 2
S = 1,099,511,627,777
Answer:
Ellen is learning the mood swing
Explanation:
According to Vernon Johnson's model for explaining behavioral changes associated with alcohol use and the emergence of dependence, there are actually four stages involved in this process: Learning the mood swing, seeking the mood swing, harmful use, and drinking to feel normal. From the example, Ellen is drinking to feel relaxed and talkative, hence she is still in the first stage of Vernon Johnson's model, as she is still learning the mood swing.
The statement that is least helpful is the following:
<span>The Supreme Court ruling in Plessy v. Ferguson (1896) wrote into law that America had two separate societies: one black and one white.
It is the least helpful because it does not mention schooling, and all the other options mention schooling. It also does not mention that one of the societies is more advantaged than the other, and other options mention that the schools for white children received more money for exemple ("</span><span>States with laws keeping schools segregated never gave equal amounts of money to their black and white schools.")</span>
