Question

The velocity of sound in air is given by the equation =20√(273+t) , where v is the velocity in meters per second and t is the temperature in degrees Celsius. Find the temperature when the velocity is 329 meters per second by graphing the equation. Round the answer to the nearest degree

Answer 1

Your formula is
\[v=20\sqrt{273+t}\]
You have to find \(t\) for a given \(v\):
\[329=20\sqrt{273+t}\]
Do you know how to solve that?

Answer 2

No how?

Answer 3

Divide both sides by 20:
\[\frac{329}{20}=\sqrt{273+t}\]
Square both sides:
\[\left(\frac{329}{20}\right)^2=273+t\]
See where this is going?

Answer 4

Umm yeah hold on let me try and solve ok?:)
