Between 1870 and 1900, the largest number of immigrants continued to come from northern and western Europe including Great Britain, Ireland, and Scandinavia. But "new" immigrants from southern and eastern Europe were becoming one of the most important forces in American life. More controversial, and much more limited, was immigration from Asia and Latin America.
The first one is done alone the second is done with someone else
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
Mildred and Montag hardly know each other, and are not in love with each other. Mildred's focus is on the "parlor family" and does not focus on Montag. When Montag asks her if she remembers where they met, she brushes it off, and cannot give him an answer. She doesn't feel as though it is an important part of their relationship. They sleep in separate twin beds in the same room, but do not really communicate with each other. They talk to each other, but there is no deep communication as there is when Montag meets Clarisse. It is also very evident that Mildred only cares for herself when she sounds the alarm on her own hvusband for having books in the house and reading poetry to her and her friends.
Meteorology is the science that looks at atmosphere and the weather. Atmosphere and weather would normally go together because atmosphere is a layer of gas that surrounds Earth and studying the atmospheric pressure could lead to the prediction and identification of weather. Meteorology made it possible for people to forecast weather through observation of the atmosphere and analysis of the changes occurring in them. Meteorology is further divided into sub disciplines which include air quality, climate change, climate modeling, etc.
