Answer:
<h2>The intensity of the sound is 3.16, approximately</h2>Step-by-step explanation:
The equation that determines decibel levels is
Where represents the intensity of the sound and the ten power represents the softest sound, that ratio is the comparison to find the decibels.
In this case, we have 125 decibels. So, we need to use this value in the formula to find the intensity
Therefore, the intensity of the sound is 3.16, approximately. Which is at the same level as a loud rock concert.
The vertex form is
Step-by-step explanation:
The given equation is a parabola. The vertex of the parabola is of the form
The parameters of the parabola are and
The vertex of the x-coordinate is given by
Thus, substituting the values of a and b in , we get,
Now, substituting in
, we get,
Thus, the vertex is
The equation of parabola to be in vertex form is
where a is the coefficient of , h is vertex of the x-coordinate and k is the vertex of the y-coordinate.
Hence, and
Thus, substituting the values in the equation of the vertex form,
Hence, the vertex form is
