Answer. The 1 in 2105 has a value of 100 (One hundred).2105 reads out to be 'Two thousand, one hundred and five'
To find the turning point of the equation, it should be recognised that we desire the point at which the gradient is 0. The gradient is given by dy/dx and hence we differentiate the equation with respect ...
As it states that it is a "linear" sequence. You can identify the pattern and recognise that the 4th and 5th terms will be, a+14b and a+18b respectively.As the 2nd term has the value 8. This mea...
y=2x(x2-1)5 --> y=uv, where u=2x; v=(x2-1)5 --> thus product rule required.u'=2v'=10x(x2-1)4Product rule: dy/dx = uv' + v'uTherefore...
Starting by factorising the curve equations: the first one factorises to y = (x-3)(x-2) and the second one becomes y=(2-x)(2+x). From this, a rough sketch of the curves can be drawn and it can be seen tha...
