A diver, when submerged in sea waters, suffers from increased pressure as he sinks. The pressure increase is described by a graph that passes through points (0, 2) and (20, 4), in atmosphere, as a function of depth, in meters. With this, determine the equation that expresses the pressure, in atmosphere, as a function of depth, in meters. And check what is the pressure suffered by the diver at 22 m depth?

step-by-step explanation:

mean or average is 40.6

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
