Sleeping in class works a charm when you are watching a movie about the history of the Catholic Church.

We had to use play-dough and cocktail sticks to contruct each of the models of: > a named ionic lattice (e.g. sodium chloride) > a named covalent molecule (e.g. water) > a named covalent (network) lattice (e.g. diamond) > a named metal (e.g. iron) So for the ionic lattice I used a ball and...

Would saying the co-efficient of the x2 being 0 be correct?

In the parabola, the coordinates of C are (0, 1) and the coordinates of the vertex (V) are (2, -3). I hope... :uhoh: Working: for coordinates of C C is y-intercept therefore y-value (constant term from equation) is 1 and x-value is 0, thus (0, 1). Working: for coordinates of vertex From...
