Answer:
I = Io 10^{β/10}
Explanation:
To find a formula for the intensity of sound waves you use the fact that there is a great range of intensity that human can perceive.
The use of logarithms are useful for this kind of systems. For example, if you want a 10 scale for the measurement of the sound level you can write:
(1)
I: intensity of sound
Io: hearing threshold
From the equation (1) you can find I in terms of Io and β. You use properties of the logarithms to obtain:
A variation of traits could be a variation of personality traits? everybody is different? what I do know Is that variation can be inherited or environmental which means that you get it from your ancestors through DNA or you get it from the environment around you
<span>Short-range forecasts are more accurate than longer range ones. Short term forecasts may use mathematical techniques such as moving averages and, exponential smoothing. Longer term forecasts not only use different methodologies, such as qualitative vs. quantitative, they also tend to consider different issues.</span>
