Firstly, this differential equation should be solved using the separation of variables method, where all y terms are moved the left hand side of the equation and all x terms are moved to the right hand si...

The decimal point needs to move to the left as the number is larger then 10 so the power of 10 in the answer will be positive.870000000.87000000.8700000.870000.87000.8700.870.87.8.7The decimal point moves...

i) Linear scale factor cubed = volume scale factor = V_B/V_A = 216π/8π = 27 LSF³ =27 LSF = 3 ii...

Firstly, we let y=f(x) so that y=e^x-4. The aim of this question is to find the inverse of y=f(x), and in order to do that, we must rearrange the question so that x becomes the subject of the eq...

The sphere has radius 6 cm. The solid cylinder has a base radius of 3cm and a height of h cm. The total surface area of the cylinder is twice the total surface area of the sphere. Work out the ratio of th...
