Question

sThe number of users on a social networking site was 45 thousand in February when theyofficially went public, and grew to 60 thousand by October.If the site is growing exponentially, and growth continues at the same rate, how many users shouldthey expect two years after they went public?NOTE: Do not round until the last step in the problem.

Answer 1

Given:

No of users in February is 45,000 and in october its 60,000.

$P=45000(\frac{4}{3})^{(\frac{3}{2})^t}$

t=2

$P=45000(\frac{4}{3})^3$$P=45000(\frac{64}{27})$$P=5000(\frac{64}{3})$$P=106666.6667$

Therefore, approximate no of users after 2 years is 106667.
