I would greatly appreciate it if someone could help me in these last few ones (had a packet, these last problems really got me stuck though) Thanks!
[7] Factor Completely:
9x^3 - x
[10] Solve, correct to three decimal places for solution.
e^(x+2) = 5
[13] Solve and round to nearest hundredth:
2 + 8 ln x = 11
[Last] To the nearest tenth of a year, how many years will it take for the population to reach half the present population? (Please show work algebraically)
Formula= P=A(1.3)^(-0.234)t
P=final population
A=20,000 people
t = time in years
