First thing since the x axis is in units of days make the domain 21 days.

- welshfella

Yes your answer to b is correct.

- freemap

Are you looking at question #3?

- welshfella

oh sorry i was looking at question 1
1(c) is incorrect though the number in parentheses after B refers to the number of days
so correct is B(12) = 0

- freemap

oh thanks so much for telling me

- freemap

that it was incorrect

- freemap

Were they less than $100 on a for number 3

- welshfella

OK
Question 3
(a) On 16th day she had zero in her account and added $100
Note the slope of that graph for the period of 1 day. After that the graph still had a positive straight slope but it was not so steep . This shows that she added a constant amount each day but was it more than $100 or lot?

- welshfella

If it was $100 each day then the graph would keep the same slope.

- freemap

ok so if shes adding $100 everyday, then yes it would be more than $100. Right? because shes keeping the same slope of a $100 ?

- freemap

@welshfella

- freemap

wait but keeping the same slope wouldn't change right, so it would be less than a $100

- welshfella

No after the 16th day she is not keeping the same slope

- welshfella

the slope becomes less
(slope of course is the Y / X

Did you see my last comment

- welshfella

Oh now i see its Yes you are right The amount added each day must be lass than $100

- welshfella

part (b)
what is your eatimate of the amount in the bank at day 21?

- welshfella

its about 3/4 of the way up the vertical axis agreed?

- freemap

2,100

- welshfella

no
the greatest balance was given as $400
so a good estimate would be 3/4 * 400

- welshfella

|dw:1450018619260:dw|

- freemap

300 or 8400

- welshfella

300 dollars
why do you say 8400?

- welshfella

because the greatest balance she had was $400

- freemap

well i looked on your graph and saw 400 and 21 and i just multiply. As i thought it was going across

- welshfella

I see
No what we are looking at each day is the balance which cooresponds the a point ion the vertical axis

- welshfella

|dw:1450019009884:dw|

- welshfella

Point P corresponds to day 21 and the balance on that day wa s $300

- freemap

ok thank you

- welshfella

For the last part
we start with 100 on day 16 and have 300 on day 21
so over 5 days theere is a an increase in $200
so amount added each day = 200/5
- and this corresponds to the slope in the graph

- welshfella

- welshfella

excuse my poor drawings!

- freemap

I see it perfectly, you're fine

- welshfella

good

- freemap

40

- welshfella

yep

- freemap

Thanks again, You've been a great help.

- welshfella

welcome
