First we start off by seeing that we are multiplying together two functions both containing x, so we want to apply the product rule. As we know the product rule is (f(x)g(x))'=f(x)g'(x)+f'(x)g(x) so we ca...

Bioethanol is a renewable fuel produced from plants, which photosynthesise to grow, taking in carbon dioxide and producing oxygen. This means there is no net increase in carbon dioxide, which is a greenho...

First multiply top and bottom by conjugate of denominator, (7-3√5), and expand(3 + 2√5)(7 - 3√5)/(7 + 3√5)(7 - 3√5)(21 + 14√5 - 9√5 - 30)/(49 + 3√5 - 3√5 - 45)Simplify top and botton(-9 + 5√5)/4Write in r...

The threshold frequency is the minimum frequency a photon can be and still just overcome the work function (Φ) of a particular material. The threshold frequency is directly proportional to the work functi...

A product analysis takes into account who the product is for, both client and user if separate, and who is designing and making the product.It also takes into account;ShapeFormColour & TextureDecorati...
