Question

i need help asap please ! D:
2 MEDALS AND FAN

Answer 1

So it increases by 600 every four hours. \[4,200+300=x\]

Answer 2

it says its incorrect @DangerousJesse

Answer 3

Do they mean 10 hours after 3,600 or 10 hours after 3,000?

Answer 4

i think 10 hours after 3600

Answer 5

it would be ten hours after 3,600

Answer 6

Oh, then just do \(3600+1500\).

Answer 7

still says incorrect..

Answer 8

how fast does it grow per hour?

Answer 9

btw, the formula at the end of the question suggest to me that this is some form of exponential growth. idk how to answer the question, but that'd be my first observation from the question. i'm sure the remaining clues are all in the question

Answer 10

600 every 4 hours?

Answer 11

here's a similar question, analyse the answer and see if u can figure it out. idk how to solve this but here's my 2 cents :) https://answers.yahoo.com/question/index?qid=20110726091015AAxk8oj

Answer 12

i tried to use an example like that already and it doesnt work.. it says its incorrect .. i dont know what im doing wrong..

Answer 13

so from what i have gathered, P is like the Population after some time t, and k is a constant. e is some form of a logarithm or eula's e or something like that but A on the other hand is the initial population... with this, we have our answer already man :)

let's see....
P=3600 after t=4 and A=3000, we're left with finding k, the constant.
so... let's do the math.

P=Ae^kt
3600=3000 * e^(k * 4)
3600/3000=e*(k*4)
36/30=e^(k*4)

what's the next thing to do?

Answer 14

multiply 4?

Answer 15

uhmmm... nah. refer to this link, see the answer given, and tell me what you think we should do ;) https://answers.yahoo.com/question/index?qid=20110726091015AAxk8oj

Answer 16

i dont understand that formula at all..

Answer 17

hmmm... take your time. i don't understand myself, i'm just trying to mimic the answer there to help solve this problem. look again, and this time. see the similarities between the answer there, and my answer here. then tell me what you thnk we should do next... take your time man ;)

Answer 18

so then ..
In[1.2]=k*4 ?

Answer 19

okay, looks like you're following :)

Answer 20

can you solve that equation?

Answer 21

no i dont know the next step from there..

Answer 22

okay. it's just a simple calculation
make k the subject of the equation. divide both sides by 4 so k becomes the subject.
0.182322/4=k

k=?

Answer 23

0.0455805 ?

Answer 24

there we go... now let's solve our main question :) shall we xD

Answer 25

now t=10

Answer 26

P is what we're looking for. but we know k and we know t... and we know A.... just plug that in and we have

P=3000 * e^(0.0455805 * 10)

P= ?

Answer 27

do i just multiply 3000 by 0.0455805*10 ?

Answer 28

nah... multiply 3000 by the result of e^(0.0455805*10)

so calculate e^(0.0455805*10) first, then multiply the answer by 3000

Answer 29

it equals 1,367.415 ?

Answer 30

nah, e^(0.0455805*10)=1.57744

multiply that by 3000

Answer 31

4,732.32 ?

Answer 32

but then i have to round to the nearest whole number..

Answer 33

do that and let me know if u get it right. i'm not sure but i just solved this with educated procedures. not that i understand so i could b wrong... let's find out :)

Answer 34

its incorrect..

Answer 35

sorry i wasn't of much help. this thread seems to suggest the same procedure http://openstudy.com/study#/updates/50c8dcafe4b09c5571442d6f

you can check it out. idk the answer though so... good luck finding it though. hopefully someone else comes along.
