dy/dx = 6x² + 4x + 9

dy = (6x² + 4x + 9) dx 

integrating gives:

y= (6x³/3) + (4x²/2) + 9x + c

y= 2x³ + 2x² + 9...

The covection current forms because the base of the pan heats up as it gains energy from the stove via conduction, the pan then subsequently heats the water that is close to the bottom. As the water gains...

Balance the carbon atoms first by adding a 4 in front of the CO2,

Water moves via osmosis; this process is where water moves from an area of higher water potential to an area of low water potential with no energy required to be inputed into the system.
