Why do sound waves move faster through the ground than through the air? a. particles of matter are packed more loosely in the ground than in the air. b. particles of matter are packed more tightly in the ground than in the air. c. air doesn’t contain any particles of matter to transmit sound waves. d. the elevation of the ground is lower than the elevation of the air space.

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 .

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it
