Hello,
a) | |PA|-π |>| |PB|-π | (see pic)
c) 3.14< x/113 <=π <22/7
==>3.14*113<x<22/7 * 113
==>354.82 <x < 355.14285
==>x=355
Answer 355/113=3,1415929203539823008849557522124
F(x) = [x] - 2 + 8
[x] is the notation for 'greatest integer function'
f(-1.8) = [-1.8] - 2 + 8 = -2 -2 + 8 = 4
The answer is 4
