r+5 r^2+4r-21
-------------- / --------------------
r^2+5r-14 r-2

 r+5 r-2
= -------------- x --------------------
r^2+5r-14 r^2+4r-21

 r+5 r-2
= -------------- x --------------------
 (r+7)(r-2) (r+7)(r-3)

 r+5
= -----------------
 (r+7)^2 (r-3)

Find a Cartesian equation for the curve and identify it. r=8tanxsecx

ANTONII [103]

R = 8 tan(x) sec(x)

In order to solve this, we are going to use the following:
r = sqrt(x^2 + y^2) //but in this case, we don't need this.
tan(x) = Y / X
X = r cos(x)
Y = r sin(x)

(r cos x)^2 = 8(r sin x)

x^2 = 8y

Can you help me solve this radical equation √y-10 = y-2 the sqrt sign is only over the y-10

matrenka [14]

$D:y-10\geq0 \wedge y-2\geq0\\
D:y\geq10 \wedge y\geq2\\
D:y\geq10\\\\
\sqrt{y-10}=y-2\\
y-10=(y-2)^2\\
y-10=y^2-4y+4\\
y^2-5y+14=0\\
\Delta=(-5)^2-4\cdot1\cdot14=25-56=-31\\
\Delta$
