00:00:00.440 --> 00:00:02.850 A:middle L:90%
okay, We know we're gonna be writing some of
2
00:00:02.850 --> 00:00:06.389 A:middle L:90%
the areas from our bounds of 0 to 8 aftereffects
3
00:00:06.400 --> 00:00:08.750 A:middle L:90%
DX. In this case, we're gonna be counting
4
00:00:08.750 --> 00:00:11.650 A:middle L:90%
up and adding all the different areas. So from
5
00:00:11.650 --> 00:00:14.289 A:middle L:90%
01 we see half a square there for the area
6
00:00:14.300 --> 00:00:16.539 A:middle L:90%
is negative. 0.5. Remember, it's below the
7
00:00:16.539 --> 00:00:20.280 A:middle L:90%
X axis. Stefan's knighted for 123 There's 2/2 spores
8
00:00:20.280 --> 00:00:22.870 A:middle L:90%
. This is one 3 to 4 of theirs area
9
00:00:22.870 --> 00:00:25.850 A:middle L:90%
of one from 4 to 6. There's area four
10
00:00:26.440 --> 00:00:29.640 A:middle L:90%
from 6 to 7. There's an area of 1.5
11
00:00:29.649 --> 00:00:33.130 A:middle L:90%
because there's one and 1/2 square from 7 to 8
12
00:00:33.200 --> 00:00:37.929 A:middle L:90%
. There's one square plus half of the squares.
13
00:00:37.929 --> 00:00:40.460 A:middle L:90%
So was half of two squares. That's one plus
14
00:00:40.460 --> 00:00:43.280 A:middle L:90%
one, which is to I have this hole up
15
00:00:43.289 --> 00:00:45.840 A:middle L:90%
and we get nine now. Use the average value
16
00:00:45.840 --> 00:00:48.399 A:middle L:90%
Formula one over B minus a. The integral from
17
00:00:48.399 --> 00:00:52.799 A:middle L:90%
zero X after vax d ox. In this context
18
00:00:52.799 --> 00:00:54.979 A:middle L:90%
, we can plug in one over eight minus zero
19
00:00:54.979 --> 00:00:57.030 A:middle L:90%
because we actually know what our A and B is
20
00:00:57.280 --> 00:00:59.590 A:middle L:90%
in this problem. Now. We already figured out
21
00:00:59.590 --> 00:01:00.869 A:middle L:90%
what is the integral, which is not so.
22
00:01:00.869 --> 00:01:04.659 A:middle L:90%
This is 18 times nine, which gives us nine
23
00:01:04.670 --> 00:01:07.049 A:middle L:90%
eights is our solution
