Please help! x^3 +y^3=9
Crank

Step-by-step explanation:

Taking the derivative of both sides with respect to x, we get

\dfrac{d}{dx}(x^3 + y^3) = \dfrac{d}{dx}(3)

\Rightarrow 3x^2 + 3y^2\dfrac{dy}{dx} = 0

Solving for \frac{dy}{dx}, we get

\dfrac{dy}{dx} = -\dfrac{3x^2}{3y^2} = -\dfrac{x^2}{y^2}

If the lengths of the legs of a right triangle are 3 and 10−−√, what is the length of the hypotenuse?
Ganezh [65]

The required length of the hypotenuse of the triangle is √19.

<h3>What is a right triangle?</h3>
  • A right triangle, sometimes known as a right-angled triangle, or more formally an orthogonal triangle, formerly known as a rectangle triangle, is a triangle with one right angle or two perpendicular sides.

To find the required length of the hypotenuse of the triangle:

Legs in the right triangle refer to the perpendicular and base.

Hypotenuse:

= \sqrt{perpendicular^{2}+base^{2}  } \\= \sqrt{3^{2}+\sqrt{10^{2} }  } \\=\sqrt{19}

Therefore, the required length of the hypotenuse of the triangle is √19.
