How much power does it take to move an object with a force of 200 newton’s a distance of 25 meters and 10 seconds

Work = (force) x (distance)

Work = (200 N) x (25 m)

Work = 5,000 Joules

Power = (work done) / (time to do the work)

Power = (5,000 Joules) / (10 sec)

Power = 500 Joules/sec

Power = 500 watts

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 .
