Ok I see
17,114
4
[]
volunteer
Do you need help starting or with one of the steps?
17,114
5
[]
student
everything
17,114
6
[]
student
I want to do all the problems as after doing these I can do the homework
17,114
7
[]
volunteer
Ok
17,114
8
[]
volunteer
I’m sorry I accidentally erased some of the picture can you insert it again
17,114
9
[]
student
yeah no problem at all!!!
17,114
10
[]
volunteer
Ok for number 2 I think we should start by drawing a graph for 1/x
17,114
11
[]
student
ok ok
17,114
12
[]
volunteer
From 1-5
17,114
13
[]
student
can we do it on the board since I am aslo writing this on my paper
17,114
14
[]
volunteer
Yea sure do you need help with graphing or can I just snip it from online
17,114
15
[]
volunteer
Cause this question isn’t really about graphing but it’s helpful
17,114
16
[]
student
uh if we could do both that would be wonderful
17,114
17
[]
volunteer
Do you know the shape of 1/x we don’t need exact values for this question
17,114
18
[]
student
no i dont
17,114
19
[]
volunteer
Ok well just by plugging in values from 1 to 5 we can graph it
17,114
20
[]
student
ok ok
17,114
21
[]
volunteer
So it will look like this
17,114
22
[]
student
what is that
17,114
23
[]
volunteer
Something like that
17,114
24
[]
volunteer
Yea that’s good
17,114
25
[]
volunteer
Now from 1-5 we can create our 4 sub intervals
17,114
26
[]
volunteer
Can you draw them as a right reimann sum
17,114
27
[]
student
like that?
17,114
28
[]
volunteer
Sorry give me a second I don’t see anything
17,114
29
[]
volunteer
I can’t see whatever you added to the board right now
17,114
30
[]
volunteer
But I will add the intervals and you can check with what you did
17,114
31
[]
volunteer
Can you see what I did?
17,114
32
[]
student
like that?
17,114
33
[]
student
what is that ovedr the 1/2 on the y axis
17,114
34
[]
volunteer
We don’t need to worry about the y values on the graphs because in our equation we will just plug in the values
17,114
35
[]
volunteer
Can you write the equation for the reimann sum now?
17,114
36
[]
student
how is that done
17,114
37
[]
volunteer
Do you me to do the equation as an example?
17,114
38
[]
student
huh
17,114
39
[]
volunteer
Do you know how to write a reimann sum?
17,114
40
[]
student
is it the sum sign
17,114
41
[]
volunteer
Yes basically
17,114
42
[]
student
like sigma
17,114
43
[]
volunteer
Yes lemme show you
17,114
44
[]
volunteer
Oh wait you already did can you finish the equation?
17,114
45
[]
student
is it that
17,114
46
[]
volunteer
Not exactly
17,114
47
[]
student
oh
17,114
48
[]
student
should I write that on my paper
17,114
49
[]
volunteer
Yes but instead of f(x) substitute that for 1/x
17,114
50
[]
student
ok ok
17,114
51
[]
student
did it
17,114
52
[]
volunteer
Ok now we write the equation for each interval
17,114
53
[]
student
ok ok
17,114
54
[]
volunteer
Ok the equation for a reimann sum interval is the height times width
17,114
55
[]
student
oh...
17,114
56
[]
volunteer
And we already know the width of each rectangle is 1
17,114
57
[]
student
how do we know
17,114
58
[]
student
we never talked about this
17,114
59
[]
volunteer
The way we figure out the width is by taking the total interval and dividing it by the number of sub intervals
17,114
60
[]
volunteer
So in this case it would be (5-1)/4
17,114
61
[]
student
ok but how do i do that this is my first time in this class i dont know anything
17,114
62
[]
volunteer
Did you teacher not teach you how to solve a reimann sum?
17,114
63
[]
student
no he got sick and llefy\
17,114
64
[]
volunteer
Liam I don’t have the time to teach you everything unfortunately
17,114
65
[ { "pii_type": "PERSON", "surrogate": "Liam", "start": 0, "end": 4 } ]
student
its okayyy
17,114
66
[]
volunteer
It the basic equation for the interval of a reimann sum is (b-a)/n
17,114
67
[]
student
oh
17,114
68
[]
volunteer
So in this case the problem tells us the start and end of the interval is 1 and 5
17,114
69
[]
volunteer
Hi, sorry you got cut off.
17,402

[]
volunteer
What would you like to work on?
17,402
1
[]
volunteer
OK, I see you're supposed to put these into categories. The first one is the checking account.
17,402
2
[]
student
1,450 ?
17,402
3
[]
volunteer
Yes
17,402
4
[]
student
ok
17,402
5
[]
volunteer
What about savings, etc.
17,402
6
[]
student
215
17,402
7
[]
student
ohh i added 170+45
17,402
8
[]
volunteer
It looks like she has a savings account 0f 3500
17,402
9
[]
volunteer
OK, that part is probably what she puts into her savings each month, not sure.
17,402
10
[]
volunteer
"Savings allocation"
17,402
11
[]
volunteer
So I would put savings allocation into the second line.
17,402
12
[]
volunteer
Does she have life insurance?
17,402
13
[]
student
i only see car insurance
17,402
14
[]
volunteer
Car insurance would go under expenses.
17,402
15
[]
volunteer
Looks like my last message got lost.
17,402
16
[]
volunteer
We have to look at the 4 different sections: Assets Liabilities Income Expenses.
17,402
17
[]
volunteer
Right now we're only dealing with assets, money & stuff she already has.
17,402
18
[]
volunteer
Does that make sense?
17,402
19
[]
student
yeah
17,402
20
[]
student
i dont see life ins.
17,402
21
[]
volunteer
Right, she doesn't have any so we leave it blank
17,402
22
[]
volunteer
So the worksheet should show the total liquid assets, 1450 + 3500 = 4950
17,402
23
[]
student
yes
17,402
24
[]
volunteer
LIQUID assets are those that it very easy and fast to convert to cash.
17,402
25
[]
volunteer
Now her household assets are things that have value but can't be immediately converted
17,402
26
[]
volunteer
She doesn't have a home, apparently, but does have a car, computer and ipad, so put those in
17,402
27
[]
student
5100
17,402
28
[]
volunteer
For what?
17,402
29
[]
volunteer
Oh, the total, yes
17,402
30
[]
student
it says its incorrect
17,402
31
[]
volunteer
What line did you put it on?
17,402
32
[]
student
an error on my part i enter a 4500 instead 4950
17,402
