To find: Whether The person G and the person C did the solution correct or not.

Answer to Problem 27HP
Neither The person G nor the person C is correct.
Explanation of Solution
Given information:
evaluating
We get
In step-2 The person G substituted value of
So the solution of The person G is wrong.
Evaluating a
We get
The person C substituted a in second equation as
She obtained correct value of
Se had to substitute value of
Here correct value of
So The person C solved correctly for
Therefore neither the person G nor The person C is correct.

- 3ur Colors are enchanting and elusive. A multitude of color systems has been proposed over a three-digits number of years - maybe more than the number of purposes that they serve... - Everyone knows the additive RGB color system – we usually serve light-emitting IT components like monitors with colors in that system. Here, we use c = (r, g, b) RGB with r, g, bЄ [0,1] to describe a color c. = T For printing, however, we usually use the subtractive CMY color system. The same color c becomes c = (c, m, y) CMY (1-c, 1-m, 1-y) RGB Note how we use subscripts to indicate with coordinate system the coordinates correspond to. Explain, why it is not possible to find a linear transformation between RGB and CMY coordinates. Farbenlehr c von Goethe Erster Band. Roſt einen Defte mit fergen up Tübingen, is et 3.
