First of all we need to find the integral of our function which is f(x). Since we are integrating with respect to x and our values are in the form of x we can use the rule of raising the power for each x ...

First, we need to work out the length of each 'part' of string. We are told Jake cuts the string into the ratio 4:3:2 , so there are (4+3+2=9) 9 parts in total. To work out how long each part is, we calc...

The equation of a straight line is: y = mx + c
There is a 'y term', y, and an 'x term', x.
The gradient of the line, m, is the slope of the straight line. The larger the value of m, the...

To find the X intercept of an equation you can make Y = 0 and then solve for X. To find the Y intercept of an equation you can make X = 0 and then solve for YWhen you plot the equation on a graph with axi...

The fact that y is directly proportional to x gives us that y=kx, where k is some constant.Firstly, we need to find the value of this constant, using the pair of values we are given in the question. We su...
