Simple math help?<br> Solve for x<br> √x+12 = √x+2
lozanna [386]
This is an impossible equation. If sqrt(x) = sqrt(x), and sqrt(x) + 2 = sqrt(x) + 12, then that would mean that 2=12, which is incorrect.

Q6: Which is the graph of the polar equation r=1/1-sin theta.
AveGali [126]

Answer:

The correct answer is C.

Step-by-step explanation:

The given equation is;

r=\frac{1}{1-\sin(\theta)}

This implies that;

r(1-\sin(\theta)=1

r-r\sin(\theta)=1

Let us write in Cartesian coordinates by substituting;

r=\sqrt{x^2+y^2} ,y=r\sin(\theta)

\sqrt{x^2+y^2}-y=1

\sqrt{x^2+y^2}=y+1

Square both sides;

(\sqrt{x^2+y^2})^2=(y+1)^2

This implies that;

x^2+y^2=y^2+2y+1

x^2=2y+1

y=\frac{1}{2}x^2-\frac{1}{2}

This is an equation of a parabola that opens upwards with a  y-intercept of -\frac{1}{2}.

The correct choice is C
