Question

The population P in 1997 for a state is given along with r, it's annual percentage of continuous growth.
P=33 millions, r=1.7%
(a) Write the formula f(x) =P erx, where r is in decimal notation, that model the population in millions x years after 1997
(b)Estimate the population in 2015

Answer 1

r = .017

Answer 2

33,000,000 e^(.017*1000000(x))

Answer 3

........

Answer 4

33? Wth?

Answer 5

Newton?

Answer 6

33 million is written out there.

Answer 7

that doesnt make sense

Answer 8

The formula says Perx which is usually just an abbreviation for f(x)=Pe^(rx)

Answer 9

its your question, not mine ;) im just the messenger....of doom!!

Answer 10

do we have to use millions of years to find 2015?

Answer 11

Dude, I have no clue, lol. That doesn;t make sense.

Answer 12

why dont it make sense?

Answer 13

large numbers are allowed to exist ;)

Answer 14

or maybe it means:

Write the formula f(x) =P erx, where r is in decimal notation, that model the population (in millions); x years after 1997

Answer 15

33,000,000 e^(.017x)

Answer 16

33 e^(.017x) seems more reasonable then.... if I parse the question correctly

Answer 17

x = 18...(2015)

33 * (e^(.017 * 18)) = 44.8134161 million

Answer 18

it wasn;t right....... :(

Answer 19

which one, the 33 e^(.017x) ? cause that seems to be the most logical one

Answer 20

correct answer was...........

Answer 21

33e^0.017x

Answer 22

33 million wasn't correct either
ARGHH!

Answer 23

:) whats the correct answer then

Answer 24

44.8

Answer 25

Ready for same problem, new numbers?

Answer 26

I got that for b already

Answer 27

you said 33 mil

Answer 28

no, I said 33 million was how you set the problem up; not the answer; you gave a 2 parter. :)

Answer 29

:(

Answer 30

part 1: set up an equation to use with this info: 33 e^(.017x)

part 2) use it to find the population in 18 years

Answer 31

33 million was part of the setup; in part 1.

Answer 32

The population P in 1991 for a state is given along with r, it's annual percentage of continuous growth.
P=34 millions, r=2.3%
(a) Write the formula f(x) =P erx, where r is in decimal notation, that model the population in millions x years after 1991
(b)Estimate the population in 2016

Answer 33

PART A :) 34 e^(.023x)

PART B ;)

2016-1991 = 25

34 * (e^(.023 * 25)) = 60.4224379

Answer 34

that wasn't it! nooooooooooo

Answer 35

I'm shocked!

Answer 36

that should be it unless google lied to me in the math..

Answer 37

That formula should be correct?

Answer 38

60.4224379.... is the same answer I get on the calculator

Answer 39

I used the formula they gave you and the numbers.... there isnt really a way to mess that up :) even for me...

Answer 40

60.4 maybe is what they want

Answer 41

I was trying the formula first the .......34 e^(.023x)

Answer 42

for A

Answer 43

i dont know how they want it formated; thats a computer program issue, but the formula itself is good

Answer 44

aw nuts.

Answer 45

it was 0.023

Answer 46

....those bastards!.... they killed kenny

Answer 47

second part was right! ;)
