Firstly you need to identify the information in the question that is key. On analysing the question, you will see that the objective is to find what x is and what y is respectively. We are given two separ...

There are several ways one can go about answering this question, one of which is to 'complete the square' by trial and error. A different, potentially easier method is to substitute the coefficients into ...

For M1, it is essential for you to be able to solve questions that involve particles moving in a straight line with constant acceleration.

The representation of symbols is listed as follow:

...

If there is a total of 100 counters, 9 + (3x) + (x-5) + (2x) = 100.

3x + x + 2x = 100 + 5 - 9

6x = 96

x = 16

Probability of picking green = (16 - 5)/100 = 11/100

f(x)=2x³+23x²+3x+5

f'(x)=6x²+46x+3

Maximum or minimum when f'(x)=0

6x²+46x+3=0

Using the Quadratic Formula: x=(-b+-squareroot(b^...
