Scientists will study how earths magnetic field changes as distance from earth changes. satellites will be placed at different distances from earth and will be used to measure the strength of earths magnetic field. Q: which of the following is the independent variable in this experiment? A: magnetic field strength
B: distance from earth
C: size of satellite
D: mass of satellite
E: gravitational force of earth

the answer is a. hope this .

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 .

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
