Some of these sources are man made although the main source is from the environment. Radon gas from rocks and cosmic rays from the sun are the main enviromental sources. For man made sources, the main sou...

Roots are where the graph crosses the x-axis, which we find by solving the equation to find x. x = -6 or x = -3

To find the new equation you use the formula y = -f (x) to find the equation of the reflected line. Using y = -f (x) on y=x² - 3x + 2 means you need to change the signs from positive to negativ...

They act as energy centres for a cell and provide a cell with energy needed to function.

To approach this question, you need to think of simple algebra and what the question is asking for. If they want c to be the subject of the formula, they are looking for the answer to be in terms of c. To...
