the air in the room has a mass of 50 kg and a specific heat of 1000j. What is the change in thermal energy of the air when it warms from 20 degrees celsius to 30 degrees celsius?

 I'm Jayden i REALLY need points i hope you have a wonderful day please mark me brainliest i don't have any friends ):  that seems hard. By

Explanation:

that would be because of both gravity and friction. so     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 .
