Answer:
Explanation:
The Second World War (WWII) was one of the major transformative events of the 20th century, with 39 million deaths in Europe alone.
Periods of hunger became more common even in relatively prosperous Western Europe.
Putting aside the very real human cost, war has also serious economic costs – loss of buildings, infrastructure, a decline in the working population, uncertainty, rise in debt and disruption to normal economic activity.
If wars alter long-term economic growth, they would permanently depress economic prospects of future generations so they had to surrender.
Mortality rate has reduced, lack of father to children and the war has cause severe hungers
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>
It's really an opinion question from your perspective of terrorism.
