Mathematics
A company produces screens of different sizes. Based on the table, could there be a relationship between the of pixels and the area of the screen? If so write an equation representing the relationship. If not, explain your reasoning.

Complete question:
standard 14.16-inch (0.360-meter) computer monitor is 1024 pixels wide and 768 pixels tall. Each pixel is a square approximately 281 micrometers on each side. Up close, you can see the individual pixels, but from a distance they appear to blend together and form the image on the screen.
A) If the maximum distance between the screen and your eyes at which you can just barely resolve two adjacent pixels is 1.30 meters, what is the effective diameter d of your pupil? Assume that the resolvability is diffraction-limited. Furthermore, 550*10^-9m as a characteristic optical wavelength. Express your answer in millimeters to three significant figures.
B.) Assuming that the screen is sufficiently bright, at what distance can you no longer resolve two pixels on diagonally opposite corners of the screen, so that the entire screen looks like a single spot? Note that the size (0.360 meters) quoted for a monitor is the length of the diagonal. Express your answer in meters to three significant figures.
a) 3.1mm
b) 1663m
Explanation:
Given:
Screen resolution =1024*768 pixel at approximately 281m each
a) Let's take sin∅ =
Solving for d we have:
d = 3.10mm
b) given:
y = 0.360m
We now have d= 3.1mm
To find L, we use:
L = 1663m
