The crude oil, which is composed of a mixture of different hydrocarbons, is heated in the bottom of the tower, so that hydrocarbons with lower boiling points boil off first. The tower gets gradually colde...

The opening scene of "Macbeth" is extremely important in foreboding the future events and setting the tone of the play. The opening stage direction of the play describes the weather on stage. &q...

In order to find the slope of the given function, we firstly have to find its first order derivative. This derivative will give us the slope of the original function at every point. To find the derivative...

To differentiate this equation we use the power rule. This means that we times the power by the coefficient, this now becomes our new coefficient. Then you subtract 1 from the old power and this becomes y...

Firstly, we can solve this equation by drawing a graph. By drawing it accurately we can see that the line intercepts the y-axis at -8 making the c value = -8. Next to calculate the gradient, m, we can tak...
