A ceiling fan with 16-in. blades rotates at 45 rpm.
Kobotan [32]

A. We're told the fan completes 45 full revolutions every minute. One full revolution is 2\pi\,\mathrm{rad}, so the fan has an angular speed of

\dfrac{2\pi\,\mathrm{rad}}{1\,\mathrm{rev}}\cdot\dfrac{45\,\mathrm{rev}}{\mathrm{min}}=90\pi\dfrac{\rm{rad}}{\rm{min}}

B. Throughout one full revolution of the fan, a point at the tip of one of the fan's blades travels the circumference of a circle with radius 16 in. The circumference is then 2\pi(16\,\mathrm{in})=32\pi\,\mathrm{in}. This means the linear speed is

\dfrac{32\pi\,\mathrm{in}}{1\,\mathrm{rev}}\cdot\dfrac{45\,\mathrm{rev}}{\mathrm{min}}=1440\pi\,\dfrac{\rm{in}}{\rm{min}}

Rationalise the equation :<br><br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7By%20%5E%7B2%7D%20%7D%7B%20%5Csqrt%7Bx%5E%7B2%7D
Nat2105 [25]

Answer:

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

Step-by-step explanation:

\textsf{Mulitply by}\quad\dfrac{\sqrt{x^2+y^2}-x}{\sqrt{x^2+y^2}-x}:

\implies \dfrac{y^2}{\sqrt{x^2+y^2}+x} \times \dfrac{\sqrt{x^2+y^2}-x}{\sqrt{x^2+y^2}-x}

\implies \dfrac{y^2(\sqrt{x^2+y^2}-x)}{(\sqrt{x^2+y^2}+x)(\sqrt{x^2+y^2}-x)}

\implies \dfrac{y^2(\sqrt{x^2+y^2}-x)}{(\sqrt{x^2+y^2})^2-x^2}

\implies \dfrac{y^2(\sqrt{x^2+y^2}-x)}{x^2+y^2-x^2}

\implies \dfrac{y^2(\sqrt{x^2+y^2}-x)}{y^2}

\textsf{Cancel the common factor}\:y^2:

\implies \sqrt{x^2+y^2}-x
