hi all! i hope ur all doing great!
ok my question is kind of simple but hard for me. the thing is that I am trying to get a head start on a concept that we will soon solve aldebraically in my class. the reason why i want to get a head start is because if i get a pretty good idea of a concept prior to the actual going over it in class, i'll get it down much quicker and better, because I am not that good of a math whiz! i just want to get this so that when it comes time for the teacher to show us, i will understand it much more better! thanks!
ok so here's a general example:
The estimated population of planet Kee2000 was 5,900,000 in year 2000, and 6,100,000 in year 2003.
Assume that population is growing EXPONENTIALLY. SEt up variables and write a forumula for the populatioon as a function of time.
i already did this part and got this:
(read as "y of x" here ) y(x)= 5,900,000 (1.034)^(x/3)
i worked it out to get an approximate value for "m" and that's what i got, 1.034^(1/3)
now here's what i don't get:
In how many years will the population equal 7,000,000 people?
How the heck would you find that one out??
i tried this:
7,000,000=5,900,000(1.034)^(x/3)
here do u divide both sides by 5,900,000 to get:
about 1.67=1.034^x
and now I am stuck...help! :yuck:
