The critical path is the path from the start to the end event continuously, with the end of one activity forming the start of the next. There is zero float and the project will be completed in the minimum...

The chain rule is given by dy/dx= (dy/du)(du/dx). If we set u=6+2x+2x²then, y=u³ thus, dy/dx=(3u²)(2+4x) = (3(6+2x+2x²)²)(2+4x). Example does not ask...

This is an example of a quadratic equation which we can solve on of two ways as it takes the form ax^2 + bx - c = 0a = 1, b = -5, c = -14 (1) Factorisation which we can do ourselves OR (2) Use the quadrat...

Firstly multiply the first equation by 2 resulting in the equation 12a + 2b = 32. Following this, add the first equation to the second equation, this will result in the 2b cancelling out with just 17a = 5...

Firstly, an expression for dy/dx needs to be found to allow us to find the gradient of the normal. As a normal is a straight line, the equation y-y₁=m(x-x₁) can be used to find its e...
