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.
Answer:
f(x) = 4(x + 6)² – 134
Step-by-step explanation:
To write an equation in vertex form, we first factor out the GCF of the first two terms. For 4x² and 48x, this is 4:
f(x) = 4(x²+12x)+10
Next we complete the square. The value of b inside parentheses is 12; we take half of that and square it:
(12/2)² = 6² = 36
We add this inside parentheses. However in order to preserve equality, we must subtract this value as well. Since the terms inside parentheses are being multiplied by 4, we multiply the 36 we subtract by 4 as well:
f(x) = 4(x²+12x+36)-4(36)+10
Simplifying, we have
f(x) = 4(x²+12x+36)-144+10
Combining like terms,
f(x) = 4(x²+12x+36)-134
Next we write the trinomial in parentheses as a perfect square:
f(x) = 4(x+6)²-134
37.29in (cubed, so put the exponent 3 after inches)
8) 2w + 2 = l
2 times width + 2 inches more equals length.
9) 4y = x
4(5) = 20
4(6) = 24
4(7) = 28
4(8) = 32
Solution:
Given Statement About South Carolina:
The interstates of I-20, I-26 and I-95 approximately form a triangle.
To Find: A warehouse which is to be built such that it is equidistant from each of the three highways.
Solution: As we know the point which is equidistant from three vertices is called Circumcenter i.e Circle passing through three vertices of Triangle.The Circumcenter can be found by the point of intersection of Perpendicular Bisectors of triangle.
Option (D) perpendicular bisectors Satisfies the above Criteria.
