Question 173741: Hello,
My question concerns growth, but I do not understand how to use the log in the equation. It reads f(x)=400 log10 (2t+3). It is asking how many animals will there be after six months. Can you help me make sense of this problem? Thank you ever so much.

You can put this solution on YOUR website! My question concerns growth, but I do not understand how to use the log in the equation. It reads f(x)=400 log10 (2t+3). It is asking how many animals will there be after six months.
:
Assume you mean log,base10, which can just be written log( ), so we have
f(t) = 400*log(2t+3)
:
Find f(t) when t = 6
f(t) = 400 * log[2(6) + 3]
;
f(t) = 400 * log(12 + 3)
:
f(t) = 400 * log(15)
:
Find the log of 15
f(t) = 400 * 1.1761
:
f(t) = 470 animals after 6 months
:
Hope this is what you mean.
