Hello everyone, this is problem five.
00:04
This is part a.
00:05
We're talking about rabbits and foxes.
00:09
So first we want to make a contour map.
00:18
So let's label it first.
00:20
So i'm just going to do the rabbits and foxes.
00:26
Okay.
00:28
And we're going to start at zero.
00:30
We're going to go to 400, 800, 112.
00:38
200 okay there and and 1600 2000 okay so and then the waxes will be started 100 then 200 and 300 let's just label 20 here use it later and a thousand so just a thousand okay, so first when times it grew zero what is happening so when times it goes zero there are 300 rabbits and then 100 foxes so then that would be at about so we'll look at it right so 300 rabbits so say like about there and 100 foxes or something like that.
01:55
This is going to be t is equal to zero.
01:59
Okay.
02:01
And t is equal to, let's say, t1.
02:05
We're going to have a thousand rabbits.
02:09
So we'll look at it right here.
02:12
And 20 foxes.
02:14
So let's say about there.
02:17
So this is going to be our t is equal to t.
02:25
Okay.
02:27
And then let's say at another time, t's equal to t2, there are going to be 2 ,400 rabbits.
02:37
So they'll be around here somewhere and 100 foxes.
02:43
So just put it around there.
02:47
Okay.
02:50
And then at another time, let's say t is equal to because it was t's equal to t2.
02:59
Tzikuru t3 let's say there are going to be a thousand rabbits so we're going back over here and 315 foxes so that'll be about here okay so one thing to note when at this point so this point is going to be when they are 20 foxes so that point here 20 foxes so that is the minimum so it's right down minimum foxes at that point and then the maximum amount of rabbits is gonna be at this point right here t's you go to t2 so this is going to be nice and rabbits.
04:12
Okay, so now we need to connect the dots...
