Natural Law was first introduced by Aristotle, but was later developed by Thomas Aquinas (1225-74). It determines the right course of action through the lens of what our natural desires are and whether th...

Perpendicular gradients multiply to give -1. The gradient of the perpendicular line (y=-3/2x+7/2) is -3/2 , so the gradient of PQ is 2/3. Using gradient formula change in y/ change in x :(4-b)/(3-a) = 2/3...

In a haloalkane, not all of the bonds are the same. We have to consider the fact that the halogen atom (for instance a bromine atom) is more electronegative than either carbon or hydrogen...

First, let's use the discriminant to check that the function actually does intersect the x-axis. b²-4ac = 4-(4 x -3) = 4+12 = 16, which is greater than 0, so we're fine.
T...
