You are asked to ind the density of a liquid. you take an iron sphere of diameter 10cm (density of iron 7800kg/m^3). you measure the weight of the sphere using a spring balance. when the sphere is completely inside the liquid the spring balance reads 30N. Calculate the density of the liquid. Will an aluminium block (density of aluminium 2700 kg/m^3) of mass 0.5kg sink or float in the liquid?

sorry idk but thx for the points and have an amazing day/ night

Explanation:

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
