The correct answer for the question that is being presented above is this one: "B. building of the transcontinental railroad --> disappearance of the frontier." The pair of events that did the first event most directly influence the second is the building of the transcontinental railroad --> disappearance of the frontier.
Answer:
Wheat was first domesticated in Mesopotamia because of a favorable climate and a great diversity of wild grains that led to crossbreeding of seeds.
Explanation:
Mesopotamia ( Western Asia )was the first place of domestication of wheat. The favourable climate of intense sunshine of old Western Asia-kuwait, Iraq,...) favours photosynthesis which ensure food production,
Besides the population of this region with wide grains, on hilly land, ensured cross pollination of these wide seeds grains with wheat varieties leading to hybridization, and selection by natural selection for domestication and eventual evolution.
Answer:
D) both B and C
Explanation:
Psychoanalysis is a school of psychology founded by Sigmund Freud in the late 19th and early 20th centuries. It is a way to resolve conflict in a subject through free association or dreams and failed actions in a person's life.
Psychophysics is a discipline that studies the physical stimuli and the sensations that those stimuli produce. It was started by Weber and Fechner and was primarily been concerned with quantifying sensations. The form used here later found a bedrock for behavioral psychology.
Hi there!
a.
To find the total amount of people that have ENTERED by t = 20, we must take the integral of the appropriate function.
Evaluate using a calculator:
b.
To solve, we can find the total amount of people that have entered of the interval and subtract the total amount of people that have left from this value.
In other terms:
We can evaluate using a calculator (math-9 on T1-84):
c.
If:
Then:
Evaluate at t = 20:
This means that at t = 20, there is a <u>NET DECREASE</u> of people at the movie theater of around 20.823 (21) people per hour.
d.
To find the maximum, we must use the first-derivative test.
Set S(t) - R(t) equal to 0:
Graph the function with a graphing calculator and set the function equal to y = 0:
According to the graph, the graph of the first derivative changes from POSITIVE to NEGATIVE at t ≈ 17.78 hours, so there is a MAXIMUM at this value.
<u>Thus, at t = 17.78 hours, the amount of people at the movie theater is a MAXIMUM.</u>
