Tiny marine organisms reproduce at different rates. phytoplankton doubles in population twice a day, but foraminifera doubles every five days. if the two populations are initially the same size and grow exponentially, how long does it take for (a) the phytoplankton population to be double the foraminifera population. (b) the phytoplankton population to be 1000 times the foraminifera population.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

++x%5e2+=+1296%2f2+=+648+
