Two curves are orthogonal if their tangent lines are perpendicular at each point of intersection. are the given families of curv

Akimi4 [234]

Hello,

$P(x,y)=x^2+y^2-ax=0\\\\
\dfrac{\partial{P}}{\partial{x}}=2x-a\\\\
\dfrac{\partial{P}}{\partial{y}}=2y\\\\


Q(x,y)=x^2+y^2-by=0\\\\
\dfrac{\partial{Q}}{\partial{x}}=2x\\\\
\dfrac{\partial{Q}}{\partial{y}}=2y-b\\\\

\dfrac{\partial{P}}{\partial{x}}*\dfrac{\partial{Q}}{\partial{x}}+\dfrac{\partial{P}}{\partial{y}}*\dfrac{\partial{Q}}{\partial{y}}=(2x-a)*2x+2y(2y-b)\\
=4x^2+4y^2-2ax-2by\\
=2(2x^2+2y^2-ax-by)\\
=2*P(x,y)+Q(x,y))\\
=2*(0+0)=0\\\\

Answer:

6) 9216π

8) 24

Step-by-step explanation:

V= 2/3πr³

r = 48/2 = 24

V = 2/3π24³

V = 9216π

V = 4/3πr³

2304π = 4/3πr³

r³= (2304π)/4/3π

r³= 1728

$\sqrt[3]{r^3} =\sqrt[3]{1728}$

r = 12

D = 2r

D = 2 x 12 = 24
