Answer:
836
Step-by-step explanation:
4 times 19 times 11
-2
We know that a positive and a negative will end in a negative result. (+) (-) = (-)
is a right triangle with base length 1 and height 8, so the area of
is
.
The average value of
over
is given by the ratio
The denominator is just the area of
, which we already know. The average value is then simplified to
In the
-plane, we can describe the region
as all points
that lie between the lines
and
(the lines which coincide with the triangle's base and hypotenuse, respectively), taking
. So, the integral is given by, and evaluates to,
The correct answer is Choice A I hope it helps :)
