assume that you are aboard a submarine. submerged in the pacific ocean. at time t=0, you make contact with an enemy destroyer. Immediately you start "porpoising". at time t=4 minutes, you are at your deepest, y=-1000meters. At time t=9 minutes,you next reach your shallowest,y=-200meters. assume that y varies sinusoidally with t for t>0.

a. sketch the graph of y versus t

b. write the particular equation expressing y in terms of t.

c. solve your equation for t in terms of y.

d. your submarine is "safe" when it is below y=-300meters. At time t=0, was your submarine safe? explian how you know. for t<15 minutes, give the times when your submarine was safe.
