The position of a particle is given by the function x=(2t3−9t2+12)mx=(2t3−9t2+12)m, where tt is in ss. What is the particle's acceleration at this times? Express your answer using two significant figures. Enter your answers separated by commas.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
