3. What are the coordinates of the points of tangency of the two tangent lines through the point (1,1) each tangent to the circl

VashaNatasha [74]

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

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

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

$y+x=2$

What is the range of the function y=-x² +1? A) y≤ -1 B) y²-1 C) y≤ 1 D) y≥ 1

MakcuM [25]

Answer:

Option (C)

Step-by-step explanation:

The minimum value of x² is 0, and the maximum value is unbounded, so therefore, the maximum value of -x² is 0, and the minimum value is unbounded.

So, this means that adding 1 to this, the range matches with option C.
