The ship embarked on the long voy-age. At begin of voyage, there were 500 ants in cargo hold of ship. One week into voyage, there were 800 ants. Assume population of ants is exponential function of time.
(a) How long did it take population to double?
(b) How long did it take population to triple?
(c) When were there be 10,000 ants on board?
(d) There also was the exponentially-growing population of anteaters on board. At begin of voyage there were 17 anteaters, and population of anteaters doubled every 2.8 weeks. How long in voyage were there 200 ants per anteater?
