An 1800-pixel by 1000-pixel display is generated on a 14-inch diagonal monitor. (a) How many pixels/dots per inch are displayed on this monitor? (b) How many pixels/dots per millimeter[mm] are displayed on this monitor? (c) What is the size of an individual pixel in[mm]?

Note that 1"=25.4 mm. Approach: Use the Pythagoras theorem to calculate the number of pixels on the 14" diagonal of the monitor for a 1800-pixel by 1000-pixel display.
