Question

On October 17, 2006, in article called "US population reaches 300 Million," the BBC reported that the US gains 1 person every 11 seconds. If f(t) is the US population in millions t years after October 17, 2006, find f(0) and f'(0)

Please can anyone help me?

Answer 1

please anyone help me...

Answer 2

that f(t) suxor

but anyway f(0) means what is the population at time zero yes? According to the headline the are starting at 300 million so well f(0) is 300 million

then it says the population grows at 1 person per 11 seconds but t is years so we will need to find out how many 11 second intervals there are in a year (since years is our time unit)...that will show how many people are added per t

then the function becomes 300 million + the number of people (p) per year times the number of years (t) .....yes? or f(t)= 300,000,000 + p(t) then you will need to find the derivative of the function to find f'(t)....easypeasy

Answer 3

could you please be more specific about 11 second interval in a year? i dont quite understand it

Answer 4

you mean I have to change 11 seconds into year, right?

Answer 5

well you need to find out how many 11 second intervals there are in a year

Answer 6

If you can find out how many seconds there are in a year ---then divide by 11

Answer 7

yea basically its like this 31536000/t :D, am I right

Answer 8

ohm im sorry 31536000/11

Answer 9

right if you know how many times 11 seconds happens in a year you know how many people are added

Answer 10

per year

Answer 11

right, thank you very much. You saved my day :D
