A gas storage cylinder in an ordinary chemical laboratory measures 2.1 cm wide and 8.4 cm high with this label on it:

Contents: N2 Gas
Pressure 15.6 atm

If the cylinder is opened and the gas allowed to escape into a large empty plastic bag, what will be the final volume of nitrogen gas, including what’s collected in the plastic bag and what’s left over in the cylinder? Write your answer in liters.

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

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 .
