In a small fishing village outside of St. John's, Newfoundland, the tides can be modeled by the function: H(t) = 2.5 cos 2π(t - 3)/12 + 4 With H(t) measured in metres and t measured in hours after midnight. When will the tide height be 2.5 m (for the first time)? a) just after 7 am b) 16.3 days c) just after 7 days d) the tide will never be this height
