Electric current is a measure of the rate of flow of charges. What this means is how many charges are flowing in a circuit in a certain time period. Mathematically this is expressed as I=Q/t where I is fo...

Firstly we would differentiate each equation with respect to t to find dx/dt and dy/dt- which gives us dx/dt=t and dy/dt=-4t^-2. Once you have found these you must divide dy/dt by dx/dt (or dy/dt x dt/dx)...

The first thing I would keep in mind when trying to categorise a text or a number of texts is that there are multiple different ways to categorise texts, but there has to be data in these texts to support...

the key to this question is to remove all the unknown denominators. to do this first move the negative fraction to the other side of the equation to get 2x+3/(x-4)=1 + 2x-8/(2x+1). then we need to combine...

Commodities are a raw material or primary good, and they are often fungible. There are three main types of macroeconomic policy. Fiscal policies use taxation and government spending to affect AD, monetary...
