Answer:y+x=2    

Step-by-step explanation:

Given

equation of circle x^2+y^2=1

Equation of tangent passing through (1,1)

Slope of tangent is given by differentiating equation of circle

2x+2y\frac{\mathrm{d} y}{\mathrm{d} x}=0

\frac{\mathrm{d} y}{\mathrm{d} x}=\frac{-x}{y}

at (x,y)=(1,1)

\frac{\mathrm{d} y}{\mathrm{d} x}=\frac{-1}{1}

Equation of line with slope

m=\frac{y-y_0}{x-x_0}

-1=\frac{y-1}{x-1}

y+x=2

An ancient Sicilian legend says that the barber in a remote town who can be reached only by traveling a dangerous mountain road
faust18 [17]

Answer:

No there cannot be.

Step-by-step explanation:

In explaining this question, I would like us to take into account who the barber is,

" the barber is the one who shaves all those, and those only, who do not shave themselves".

This barber cannot be in existence because who would shave him? If he should shave himself then there is a violation of the rule which says he shaves only those who do not shave themselves. If he shaves himself then he ceases to be a barber. And if he does not shave himself then he happens to be under those who must be shaved by the barber, because of what the rule says. But then he is the barber.

This lead us to a contradiction.

Neither is possible so there is no such barber.
