Food is relatively price inelastic as it is considered a necessity which means that everyone needs it. If price were to rise there wouldn't be any change in consumption as people require it to live so the...

Using conservation of energy i.e calculating the total kinetic and potential energy at a trivial point, then solving for the velocity at the point in question by knowing the potential energy of the partic...

We can see from the term x^2 that this equation is quadratic. To solve it, we need to get it into the form ax^2 +bx +c = 0. Subtract 25 from both sides to reach this form:So we have the equation x^2 -5x -...
