The most important thing to remember about chemistry equations, whether these are word or symbol equations, is that you must always have the same amount of each species (element or molecule) on both sides of...

The first thing we should note here is that we are looking for the area, so we need to recall the formula for the area of a right-angled triangle: Area = (base x height) / 2 Next we can input our values give...

First we must consider for which values of x the equation: 3/(x+3) = (x-4)/x is undefined. In this case, x=-3, and x=0. Now we must consider each of the cases, x<-3, -3<x<0, 0<x Case 1 (x<-3):...

When writing to persuade, you need both fact and opinion. You need to offer your opinion and then present facts that give your opinion basis.

Hint: the chain rule states that for y=u(x) ^a, the derivative will be dy/dx = dy/du * du/dxSo we just need to find dy/du and du/dx!In this case u(x)=x-3, so du/dx = 1.from y=u^(-3), dy/du = -3u^(-4).This me...
