Bacterial Growth. How to find k? (Word Problem)

[From: ] [author: ] [Date: 11-10-06] [Hit: ]
4k = ln 9.k = ln 9.539 / 4 = .563847 -Just insert the values youve been given; B =9539,9.k = 2.......
The number of bacteria present after t minutes is given as B=1000e^kt. Amount of bacteria is 9539 after 4 minutes. Find k.
Please show steps. Oh my goodness. Help?

just take natural logs ! no need to panic !

9539 = 1000e^4k

e^4k = 9.539

4k = ln 9.539

k = ln 9.539 / 4 = .563847 <---------

Just insert the values you've been given; B =9539, t = 4

9539 = e^(k*4)

Take natural logs

ln(9539) = k*4

9.1631439371 = k*4

k = 2.29 to 2 dp <<<
