Every open-sided floor or platform that rises four feet or more above the adjacent floor must be protected on all open sides by a standard railing.
true or false?

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

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 .

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
