There are topics such as genetics in biology and that ultimately effects our lives because our genetics is what makes you, you
Answer:
There are a few factors that influence a shift in the demand curve, and some of them are income, trends, prices, expectations, structure of the population.
Explanation:
The change of the shift of the curve appears when the whole demand curve is moving to the left or the right.
This movement depends on the price if the other factors that influence the moving are stable. Everything else, except the price, will move the curve to the left or the right.
1. Using washers, the volume is given by the integral
We're using washers whose centers depend on the value of 
, hence we integrate with respect to
2. The area of the given region is given by the integral
To compute the integral, first consider the substitution 
, or 
so that 
. Then 
and 
, so the integral is equivalently
Integrate by parts, taking
so that
and 
, so the area is
For the remaining integral, substitute 
, so that 
. Then 
and 
:
(notice that the integral is improper)
