Let z be a cube root of 1 such that: z^3 = 1 z^3 - 1 = 0 Factorise: (z-1)(z^2 + z + 1) = 0 Then, z=1, the real root, or: z^2 + z + 1 = 0 with z not equal to 1 Use quadratic equation: z = (-1 +- sqrt(1-4))...

This is a maths problem, which I believe is best taught by live demonstration and explanation while constantly promtpting the student to suggest further steps if they are able. If they are not, then you s...

First of all, the concept of genetic modification needs to be understood. Proteins are coded for by genes in the DNA of an organism, with each gene coding for a different protein. We utilise the fact that...

Draw a diagram of forces on a single particle at surface of water.

Water is stationary in reference to train, thus when including decelerating force, resulting force is zero.

Balance horrizo...

Selling price of novelty mug= £4; Cost of making mug= £2; Distribution cost= £50 for every 100 mugs sold. Therefore, 1) 5000 x £4= £20,000; 2) 5000 x £2= £10,000 3) £20,000- £10,000 = £10,000; 4) 5000/100...
