A musician is playing a tuba. If he plays a note and holds it for a significant length of time, the air pressure near the opening of the tuba can be modeled by the following function. p(t)=101,3259-0.4 cos 326.2t In this equation, p (t) represents the air pressure in pascals, and f is the time in seconds. Find the following. If necessary, round to the nearest hundredth.
