Answer: t = ln 3/0.4 (answer as a logarithm)
t = 2.747 (answer to the nearest thousandth)
Step-by-step explanation:
300 [tex]e^{0.4t}[/tex]= 900
[tex]e^{0.4t}[/tex]= 900/300
[tex]e^{0.4t}[/tex]= 3
ln ([tex]e^{0.4t}[/tex]) = ln 3
0.4t * ln e = ln 3
0.4t = ln 3
t = ln 3/0.4 (answer as a logarithm)
t = 2.747 (answer to the nearest thousandth)
