y is inversely proportion to the square of x. y=10 when x=5. Express y in terms of x.

y is proportion to 1/x 2 . This can be written as y=k/x 2 where k is a constant of proportionality. Given that y=10 when x=5 , k can be found as yx 2 which is equal to 25. Therefore; y=25/x 2 .

The curve y = 2x^3 - ax^2 + 8x + 2 passes through the point B where x=4. Given that B is a stationary point of the curve, find the value of the constant a.

As B is a stationary point, the value of dy/dx at this point must be equal to 0. Differentiating y gives this to be dy/dx = 6x 2 -2ax+8. At point B , x=4 . This gives the relation 104=8a and thus gives a=13.
