During tug-of-war, team a does 2.20*10^5 j of work in pulling team b 8.00m. what average force did team a exert

As we know that work done is defined as product of force and displacement

so here we will have

so here we know that

also we know that

now we will have

so it will have 27500 N force on it

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

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 .
