A is the point (-2,4) and B is the point (7,1). Find the length of AB giving your answer in its simplest surd form.

AB = 3

Step-by-step explanation:

Calculate AB using the distance formula

d =

with (x₁, y₁ ) = A (- 2, 4) and (x₂, y₂ ) = B (7, 1 )

AB =

     =

     = ×

     = 3

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.
