Answer:
Second option (B)
Explanation:
The inequality, x ≤ 1,200, can he represented in a number line as follows:
Since x is less "than or equal to 1,200", it means 1,200 is included in the possible values of x. On the number line, the circle of the arrow which starts from 1,200 would be shaded (full). The arrow will point towards our left hand side. This also implies that 1,200 is the maximum possible value of x.
The number line in the second option (B) is the represents the inequality correctly.

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)
