Answer 2

Change in population / Change of time

Answer 3

so .4/5?

Answer 4

are you measuring time in months or years?

Answer 5

i did it in years. it doesnt specify how to do it in the question though.

Answer 6

either way, it will be some value per unit time and using the formula @AccessDenied gave (which is correct) I suppose it should be easy, haven't worked it out myself but i guess it's self explanatory :) difference it population/time elapsed ...

Answer 7

cool pic mario

Answer 8

so the answer is .08?

Answer 9

0.08billion per year... rate of change of world population... you got it :)

Answer 10

4. In class we have studied the exponential growth model. Assume that the population
of the world is growing exponentially. Use the data that you found in question 2 to
write a model for the population P of the world t years after July 1, 1965. The units
on P should be billions of people.

Answer 11

i need help with this question ^^^^

Answer 12

sorry but I don't know anything about the exponential growth model, you could ask in the chat though... i'm not very concentrated with OS help or chat right now :/ sorry

Answer 13

Poe^rt I think

Answer 16

what level math is this? Just wondering, sometimes it helps us.

Answer 17

calc

Answer 18

Is this an integration problem?

Answer 19

exponential growth

Answer 20

Don't you need a function? Were you given a function? Your instructions mention the use of question 2.

Answer 21

2. Find the world population on July 1, 1965 and July 1, 1970. Round your answer to the
nearest tenth of a billion. You will need to do some research to answer this question.
Be sure to cite the source that you used for your information and write one sentence
indicating why your source is credible, based on what you learned in question 1.
• The world population on July 1, 1965 was 3.3 billion. On July 1, 1970 the population increased to 3.7 billion.
• Source: Compiled by Earth Policy Institute from United Nations Population Division, World Population Prospects: The 2010 Revision, electronic database, at http://esa.un.org/unpd/wpp/index.htm, updated 3 May 2011; UNFPA, “World Population to Reach 7 Billion on 31 October,” press release (New York: 3 May 2011).
• It is a credible source because it comes from a database that collects world population statistics.
Thats question 2 ^^^^^^^^^^^^^^
