The function f(x) = 6e^0.013x describes the world population, f(x), in billions, x years after 2000 subject...

Question

to a growth rate of 1.3% annually. Use the function to find the world population in 2070.

Also: log7^sqrt7 ---How do I solve this? ( I know it's easy, I'm just having a brain lapse :-/

Answer 1

f(x) = 6e^0.013x
f(2070) = 6e^0.013*70
f(2070) = 14.905935200 billion

log7^√7 = (√7)log7 = 5.1484 if log is ln
if log is log[10], (√7)log7 = 2.2359
