Which graph shows the equation V = 4 + 2t, where V is the total volume of water in a bucket and t is the elapsed time in minutes?

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.

hope this < 3

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website
