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) = 70 + 4 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.)

(a) 9:00 A.M.

mmHg

(b) 8:30 A.M.

mmHg

(c) Noon

mmHg

(d) 6:00 P.M.
