1. (2 points) the starship enterprise just picked up a strange creature called a tribble.
at first there was only one, but overnight the tribble spawned 3 more tribbles just like
it. the next night, each tribble spawned 3 more tribbles, and this continued happening
each night. how many tribbles were on the starship after the 7th night? (hint: show
that the number of tribbles follows the geometric series.)
pls y’all
