Boyle's law says that the volume of a gas varies inversely with the pressure. when the volume of a certain gas is 5 l, the pressure is 304 kpa (kilopascals). what is the volume when the pressure is 80 kpa ?

Consider the function f(x)=−2/3x+5 . what is f(1/2) ? enter your answer, as a simplified fraction, in the box. f(1/2)=

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
