1
00:00:00-->00:00:02
Could we if we really wanted
to use this new graph

2
00:00:03-->00:00:05
for our combined function graph
to estimate how much

3
00:00:06-->00:00:09
the combined population grew
during the first

4
00:00:10-->00:00:12
7 months of 2002 so here's the first
7 months all the way

5
00:00:13-->00:00:16
off actually we change that to
7 months didn't we it doesn't

6
00:00:17-->00:00:22
it only goes till 6. Nonetheless
through those first six months.

7
00:00:23-->00:00:26
We've got our combined function drawn
for us could you use it to

8
00:00:27-->00:00:32
figure out how much the combined
population grew? And if so how?

9
00:00:33-->00:00:35
You don't actually have to do it,
just find the number.

10
00:00:36-->00:00:42
Could you and how? What are you
thinking?

11
00:00:50-->00:00:54
Ryan? I think it's possible. How?
He said i think it's possible.

12
00:00:55-->00:01:00
How? One and half plus six that's
how much people grew because those

13
00:01:01-->00:01:10
are positive and they are always
going to increase. OK. It is from

14
00:01:11-->00:01:13
people coming in. Ok how can you
tell how many people come in?

15
00:01:14-->00:01:32
It started at 0 and went all
the way to 500. Ok so

16
00:01:33-->00:01:37
alright I have a question then if
from here to here it changes

17
00:01:38-->00:01:40
positively from a hundred to five
hundred does that mean I gain five

18
00:01:41-->00:01:46
hundred people in those first 4
and some odd months. If from here to

19
00:01:47-->00:01:56
here it goes from zero to five hundred
people over the course of those

20
00:01:57-->00:02:01
4 and a half months not 4 because
we are starting at like one and a half.

21
00:02:02-->00:02:06
It is 3 months, approximately 3 months.
Does that mean I gain 500 people?

22
00:02:07-->00:02:11
Over the course of those 3 months,
who said no? How come I agree with you

23
00:02:12-->00:02:20
why not? Cause thats how much you gain
every month and then every 3 months

24
00:02:21-->00:02:25
Ok so what do you mean this 500 represents
what I think your talking about

25
00:02:26-->00:02:28
are you talking specifically about
this one? And what about this value

26
00:02:29-->00:02:36
that Ryan was talking about that 4 and
at just this point yes. Well

27
00:02:37-->00:02:42
yes ladies and gents let's back up again
this looks like peak in population

28
00:02:43-->00:02:48
change of about 500 that's fine a
little after into the fourth month.

29
00:02:49-->00:02:50
I don't know what day it is, but somewhere
into the fourth month is where this

30
00:02:51-->00:02:56
happens but whatever day this is maybe
its 4.4 months I don't know.

31
00:02:57-->00:03:01
But this 500 means what again? Someone
new because I think Danielle already

32
00:03:02-->00:03:06
knows it, Gina. This 500 means what
again for 4 point something months.

33
00:03:07-->00:03:14
I think they have changed by 500.
They changed by 500 or gained 500 when though?

34
00:03:15-->00:03:21
Over the course of all this or on that day?
On that day. On that day yes. So this

35
00:03:22-->00:03:27
positive change of 500 how ma ny people
I gain right on that day. How many people

36
00:03:28-->00:03
did I gain on that day? 400. About 400
so how many did I gain altogether? 900
