The impedance of a material is Z=rhoc, the density times the speed of sound. Consider the following information: Zlung=0.18×106kg s/m2. Zfat=1.34×106kg s/m2. What fraction of the incident intensity of a sound pulse will be reflected when sound travels from fat into lung? Express your answer in percent.

i would like to make dinner for my mom, dad, and sister

im sorry i dont know

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 .
