{{{y=ab^x}}}


{{{system(500=a*b^10,1700=a*b^35)}}}


{{{17/5=b^25}}}


{{{b=1.0502}}}

-

{{{a=1700/b^35}}}

{{{a=1700/(1.0502^35)}}}

-----------------------------------------------
a). What was the initial size of the culture?
----------------------------------------------


Initial size of culture probably  300.
(Computed to 306, but only two significant figures at best should be taken.)


---------------------------------
b). Find the doubling period.
--------------------------------


Starting with {{{y=306*1.05^x}}},

try {{{2=1*1.05^x}}} and solve for x.




You try the rest...

c). Find the population after 65 minutes.
---------------------------------------------
d). When will the population reach 11000?
