I need this question answered so I can use it to study from.

1. Everybody's blood pressure varies over the course of the day. In a certain individual the resting diastolic blood pressure at time t is given by B(t) = 90 + 9 sin(t/12),where t is measured in hours since midnight and B(t) in mmHg (millimeters of mercury). Find this person's diastolic blood pressure at the following times. (Round your answers to one decimal place.)
