14) A plant that floats on the surface of rural bodies of water is known as duckweed.
The initial mass of a population of duckweed
is 500 kg. The mass of the population triples
every 45 hours and can be represented by
the function m(t) = 500 * 3*
345, where t is
time in hours.
=
Determine how many hours would pass
for the duckweed to grow to a mass
triple the original size.
