By taking the formula F=m*a, and rearranging the make a the subject, we get a=F/m. Then by substituting in the values given we can work out that a=30/10=3. The units of acceleration are ms^-2 so...

By factorising the expression, (x-5)(x-4)=0. This means that either (x-5)=0 or (x-4)=0. By solving these equations we can work out the solutions to be x=4,5.

Research into the cognitive approach is largely based upon computor models, which uses computor terminology to describe human cognition, for example 'input' would represent sensory information from our en...

First thing to do is to find the stationary point of the curve. This is done by differentiating the function and then equating to zero, as the gradient of the stationary point is zero. Setting dy/dx to ze...

A merit good is a good which has positive externalites and therefore people do not consume enough of them. For example, vaccinations.

A public good has two characterisitics, it is non-rival: this m...
