The amount he charged up front for his work
Answer:
y = 4.2
Step-by-step explanation:
Pythagorean thearom: a^2+b^2=c^2
3^2+3^2=c^2
9+9=c^
sqrt18=sqrt/c^2
4.2 = c
X^3 - x^2 - x + 1 = 0
Plug in x = 1:-
1 -1 - 1 + 1 = 2 - 2 = 0 so x =1 is a root.
If it has multiplicity 3 then the function will factor to (x - 1)^3:-
(x - 1)^3 = (x - 1)(x^2 - 2x + 1) = x^3 - 2x^2 + x - x^2 + 2x - 1
= x^3 - 3x^2 + 3x - 1 so it is FALSE
