Question 1016718: The relationship between the intensity of sound (W/m^2) and the distance from the source of the sound is represented by the equation I=k%2Fd%5E2. If you sit only 1 meter away from the stage at a rock concert, the intensity of sound is about 0.1 W/m^2. If Vanessa does not want the sound intensity to be any more than 0.0001 W/m^2, how close to the stage can she sit?

k=I%2Ad%5E2
k=0.1%2A1%5E2
k=0.1



d%5E2=k%2FI
d=sqrt%28k%2FI%29-----plug in the given values.
