The top and bottom margins of a poster 6 cm each, and the side margins are 4 cm each. if the area of the printed material on the poster is fixed at 384 square centimeters, find the dimensions of the poster of smallest area. (list the smallest dimension first)

Ultra-high temperature (uht)

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

The actual answer is c force stays the same while direction changes
