決意する is the common modern verb for 'resolve' or 'decide', used instead of the classical 期す in sense 2.
Classical verb derived from the kanji 期 (period, time, expectation). The form 期す is a precursor to the modern suru-verb 期する. Its exact historical derivation is uncertain, but it has been used in literary Japanese to express expectation or resolution.
