Question, what if we forgot +c.

Question, what if we forgot +c.

as harsh as it may sound, if you leave out the +c they deduct marks

Question, what if we forgot +c.

It depends, according to my teacher they usually have one integration question wherein they allocate one mark for noting the +c, however in the other ones you'd be marked the same. However, if you forgot +c in a question that involves finding the equation from the derivative though you should lose the mark whatever the situation. (I might be completely wrong though)

You'd lose a mark mate.

Yes there are that amount of members but they're not asking how much money the site earned on day 12 it is asking how much money it earned during the first 12 days so the answer would be:
27*0.005((2^12)-1)/(2-1)

yeah. On Day 12 there was a total of 55296 members (and that includes Day 1, Day 2... read the Q. again)
So I'm pretty sure you just multiply that by 0.5 and get $276

Its annoying that before the test I kept reminding myself to do +c if needed....

No, because on day 12 there were 55296 members, but on day 11 there were 27648 and so on. So for each day they earn 0.5 c for each member, so you are earning more than 0.5c for a member that joined on the first day, so you have to take the sum of the members from day 1-12 and you get $553

Yeah that's right

I think i got $553.
I nearly gave up on this, then i had a brainwave on how to do it.
I now can't remember how i did it.

Depending on ANY Marker.


You DO lose mark.

I got $553 but didnt round off. GG.

Dont think I did it to the nearest dollar...


1 mark gone. weeeeeeeeeeee

Question, what if we forgot +c.

Bound to be a couple silly ones throughout. I forgot +c as well on the hence integrate question in Q4.

 

[Tennisaddict]

wtf? There is not congruency rule with AAA.

There is a similar triangle rule with AA.. therefore by putting in congruent triangle, you are incorrect. You can't have a 'ratio' with congruent triangles anyway.


And, instead of "(equal intercept theory)" I wrote "equal transversals of parallel lines"

I meant similar!

 

[friend177]

0.5 cents shit I think I did 0.5 dollars wtf I mean what's less than a cent? Uh....0.5 cent Fml

 

[snorelacks]

0.5 cents shit I think I did 0.5 dollars wtf I mean what's less than a cent? Uh....0.5 cent Fml

Exactly what I did. Fml.

Didnt you just have to times Sum(21) by 0.5?

 

[jamesfirst]

Didnt you just have to times Sum(21) by 0.5?

ye.


then convert it into dollars. I didn't do that I think.

 

[lobster1234]

for q5 aii i think wasnt it 16 days?
27*2^16 >1000000
