Start by converting these mixed numbers into top-heavy fractions: 3 and 1/2 becomes 7/2 (3x2=6; 6+1=7)2 and 4/5 becomes 14/5 (2x5=10; 10+4=14)Then use the 'KFC' formula - 'Keep it, flip it, calculate it':...

So you have the following: ((1/3)(c^2))^3 which can be rewritten as:((1/3)(c^2))x((1/3)(c^2))x((1/3)(c^2)) at which point it becomes easier to simplify:= (1/3)x(1/3)x(1/3)xc^(2+2+2)= (1/27)c^6

A singular matrix is one which has a determinant of zero. This has several important consequences depending on the context in which the matrix is being used: Firstly, it implies that the matrix is not inv...

Look at the graph for two points that you can read the x and y values for easily. Then draw a triangle using these two points and use a ruler to draw a dotted line or just to help you read the x and y val...

To solve a simultaneous equation we use a method known as elimination. We choose to 'eliminate' or remove the X or Y term. To 'eliminate' x we must firstly determine the lowest common multiple 3 and 2 (as...
