Hello,

$f(x,y)=sin(xy)-x^2\\

 \dfrac{\partial f}{\partial x} =cos(xy)*y-2x\\
 \dfrac{\partial f}{\partial y} =cos(xy)*x\\

 \dfrac{dy}{dx} =-\dfrac{\dfrac{\partial f}{\partial x}}{\dfrac{\partial f}{\partial y}}\\

=- \dfrac{cos(xy)*y-2x}{cos(xy)*x}\\\\

=- \dfrac{y}{x}+ \dfrac{2}{cos(xy)} \\

Lisa has 3 quarts of milk. Sanjay has 12 pints of milk. Who has more?

Ira Lisetskai [31]

Sanjay, because quarts are twice as big as pints.

Step-by-step explanation:

Given

Milk quantity for Lisa = 3 quarts

Milk quantity for Sanjay = 12 pints

We have to convert both quantities in same unit so that we can compare both quantities.

We know that there are two pints in a quart.

So,

Lisa will have:

3*2 = 6 pints of milk

Hence,

Sanjay, because quarts are twice as big as pints.
