A pilot bails out of his airplane at a certain altitude and hits the ground after 83.7 seconds. His terminal velocity is 200 km/hr. How many seconds into his fall will he reach terminal velocity? What was his altitude when he bailed out? Please show steps.

im sorry i dont know

a. are

i believe the answer is a hope it and is correct

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 .
