Question

2) The population P in 1999 for a state is given along with r, its annual % rate of continuous growth P=10 Millions, r = 2.6% Estimate the population in 2019 = ?

Answer 1

interent down, we had a bad storm roll through

Answer 2

yes still interested

Answer 3

By the way, did you realize that the phrasing of yesterdays problems were not good, and I conceived something which was not correct

Answer 4

For that problem on cumulative quadratic equation, .....

Answer 5

It meant that the equation itself provided the cumulative result

Answer 6

yes

Answer 7

So our result would be f(5)-f(4)

Answer 8

I am sorry, but the phrasing was too poor, and I didn't get it at all

Answer 9

sorry.. ok can you help me with this one?

Answer 10

2) The population P in 1999 for a state is given along with r, its annual % rate of continuous growth P=10 Millions, r = 2.6% Estimate the population in 2019 = ?

Answer 11

Did you actually understand the problem ?

Answer 12

I mean did you understand what its saying?

Answer 13

no because i tried to use the formula 10e^.026(20) yet I get the wrong answer

Answer 14

Before using the formula you must understand what its being said...

Answer 15

What is the precise meaning of the term "given along with r"

Answer 16

time

Answer 17

?

Answer 18

I don't know, but I feel that it could have been better phrased

Answer 19

Is it from some book?

Answer 20

2) The population P in 1999 for a state is given along with r, its annual % rate of continuous growth P=10 Millions, r = 2.6% Estimate the population in 2019 = ? r is the 2.6

Answer 21

r is the decimal notation

Answer 22

Hey! I have the feeling you are actually phrasing the problem, it can't be from some printed material. Am I right?

Answer 23

thats what it says in the book, then it says write the formula PE^rx where r is the decimal notation

Answer 24

and that models the population in millions of years x after 1999

Answer 25

Listen the problem can't be solved if I don't understand the english. You see, I can't make out any thing from this part "its annual % rate of continuous growth P=10 Millions, r = 2.6% ". This is some kind of broken sentence. It makes no sense .

Answer 26

then it says the population in 2019 will be?

Answer 27

just a min I will write he whole thing and paste it correctly

Answer 29

2) The population P in 1999 for a state is given along with r, its annual % rate of continuous growth P=10 Millions, r = 2.6% - use the formula f(x) = PE^rx, where r is in decimal notation, that models the population in millions x years after 1999. The population in 2019 will be approximately ? million

Answer 30

Tell me what you wanted to say

Answer 31

I did it on the calc again

Answer 32

I did it like this 10e^(.037(20) and it came out with 17

Answer 33

I used extra parenthasis

Answer 34

(.037(20))

Answer 35

Yes, it is something around 16.8 ............

Answer 36

So is that ok?

Answer 37

I think so

Answer 38

how did you get 16.8?

Answer 39

So any more problem?

Answer 40

I am sorry there was some connection problem here, I got disconnected. Please visit the link (given on the previous post) and post your email address....

Answer 44

I forgot your email address

Answer 45

\[A=10\times e^{.026\times 20}=10 e^{.52}=16.82\]
rounded. so 16.82 million
