A14 gram sample of a substance that's
used to preserve fruit and vegetables has
a k-value of 0.1092.
n = noekt
no - initial mass (at time t = 0)
n = mass at time t
k= a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days

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.
