The depth of water, d(t) metres, in a seaport can be approximated by the sine function d(t) = 2.5sin 0.164pi(t - 1.5) +13.4, where t is the time in hours. a) A cruise ship needs a depth of at least 12 metres of water to dock safely. For how many hours in each period can the ship dock safely? Round you answer to the nearest tenth of an hour. The answer is 11.5 h. Can anyone help me in this questions please and thank you :) |
