Sound intensity, in decibels, d, can be written using a comparison factor, x, that compares sound intensity to the standard threshold of hearing. d = 10log(x) A sensor measures the sound intensity, in decibels, of an office over time. The decibel reading was consistently above 50, but never above 70. On what interval is the factor by which the office noise is related to the standard threshold of hearing? (17, 18.5) (17, 18.5] (100,000, 10,000,000] (100,000, 10,000,000)
Answer: (100,000, 10,000,000]
Step-by-step explanation:
The interval is given by ( 100,000 , 10,000,000], the correct option is C.
What is the Threshold Value ?The threshold value is the minimum value above which the desired results can be expected.
The decibel reading was consistently above 50, but never above 70.
d = 10log(x)
50 = 10log(x)
5 = log x
10⁵ = x
x > 10⁵
d = 10log(x)
70 = 10log(x)
x = 10⁷
From the given data
x ≤ 10⁷
Therefore, the interval is given by ( 100,000 , 10,000,000], the correct option is C.

Answer:
Step-by-step explanation:
we can subsitiute 3 and -1 for x and y respectively to get 3A - 4 = 2. After this you add 4 to both sides and get 3A = 6. divide by 3 and you get a = 2
f(x) = 3x + 10, g(x) = x - 2, Find g(f(x))
Answer with step-by-step explanation:
If g(x) = x - 2, then g(f(x)) = f(x) - 2. So the whole equation would be: 3x + 10 × x - 2. Simplified: g(f(x)) = 13x - 2
Hope this helped!
The composite function g(f(x)) = 3x + 8 if the f(x) = 3x + 10, g(x) = x - 2 after applying the concept of the composite function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
f(x) = 3x + 10
g(x) = x - 2
It is required to find the g(f(x))
g(f(x)) representing the composite function:
Plug f(x) = 3x + 10
In the function g(x):
g(f(x)) = (3x + 10) - 2
g(f(x)) = 3x + 8
Thus, the composite function g(f(x)) = 3x + 8 if the f(x) = 3x + 10, g(x) = x - 2 after applying the concept of the composite function.

I Need A Expert To Answer This! Find The Measure Of The indicated Angle In The Diagram.
Answer:
So,you're answer will be 21°{degree}..
Answer:
m∠YPQ = 159°
Step-by-step explanation:
m∠QRP = 107
m∠RQP = 52
m∠RPQ = x
m∠QRP + m∠RQP + m∠RPQ = 180°
107 + 52 + x = 180
159 + x = 180
x = 21°
m∠RPQ = x = 21°
m∠RPQ + m∠YPQ = 180°
21° + m∠YPQ = 180°
m∠YPQ = 159°

4. Two times a number added to another number is 25. Three times the first number minus the other number is 20. Find the two numbers.
Answer:9 & 7
Step-by-step explanation:
Let x be the first number and y be the second.
2x + y = 25
3x - y =20
1) Add them together.
5x = 45
x = 9
2) Solve for y.
2(9) + y = 25
y=7
3) Check your work on the other equation.
3(9) - (7) = 20
27 - 7 =20
20 = 20

Write the equation of a line perpendicular to 5x+3y=9 and passes through the point (-10,4).
y=3/5x+10
Explanation:
first convert to slope intercept form y=mx+b, 5x+3y=9 that will be y=-5/3x+3, to be perpendicular, the slope has to be an opposite reciprocal so -5/3x has to be 3/5x, then pass through the point (-10,4), the equation will be y=3/5x+10
