Question
The description for a certain brand of house paint claims a coverage of 470 ft2/gal. (a) Express this quantity in square meters per liter. (b) Express this quantity in an SI unit (see Appendices A and D). (c) What is the inverse of the original quantity?So i used the "chain" multiplication as this book desripes it, and here is what i got
a)11.53m^2/liter
b)11532.78m^-1
c) help
the way im used to finding an inverse is like if you have F(x) = 4x+2 so...
y=4x+2 ----> x=4y+2 ----->y=(x-2)/4
F^-1(x)=(x-2)/4 thats the easiest example i could think of.
Explanation / Answer
c) It is NOT an inverse function, the answer is 1/470 gal/ft^2
