The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as L = 10 log StartFraction I Over I 0 EndFraction, where I 0 = 10 Superscript negative 12 and is the least intense sound a human ear can hear. What is the approximate loudness of a rock concert with a sound intensity of 10–1?.
The approximate loudness of a rock concert with a sound intensity of 10⁻⁹ is 110 Db.
What is a logarithm?Logarithms are another way of writing exponent. A logarithm with a number base is equal to the other number. It is just the opposite of the exponent function.
The loudness (L) measured in decibels (Db), of sound intensity (I), measured in watts per square meter, is defined as
[tex]\rm L = 10 \ log \ \dfrac{I}{I_o}[/tex]
where [tex]\rm I_o = 10^{-12}[/tex] and is the least intense sound a human ear can hear.
The approximate loudness of a rock concert with a sound intensity of 10⁻¹ will be
[tex]\rm L = 10 \ log \ \dfrac{10^-^1}{10^{-12}}\\\\\rm L = 10 \ log 10^1^1\\\\L = 10*11\\\\L = 110[/tex]
The approximate loudness of a rock concert with a sound intensity of 10⁻¹ is 110 Db.

Pls help me on this problem I’m confused
Answer:
30 × 24 = 720 inches
since there are 12 inches in a foot
720 ÷ 12 = 60
60 feet converted to yards is 20 yards
50 - 20 = 30
they should have 30 yards of string left over

Jordan and Raj each bake 7 batches of muffins. Jordan makes 18 muffins per batch, and Raj makes 15 muffins per batch. They combine their muffins and put all of them into boxes. They fill as many boxes as possible with 6 muffins each. They place the remaining muffins in the last box.
Enter your answers in the boxes.
How many full boxes do they make, and how many muffins will be in the last box?
i cant understand it much.
Answer:
Step-by-step explanation: Jordan's batches have 18 muffins a piece he made 7 bathes so 7 times 18 equals 126 muffins. Raj's batches have 15 muffins per batch which he also makes 7 batches of so 7 times 15 is 105. The boys then add all their muffins together so 126 muffins plus 105 muffins is 231 muffins. They then have to divide the muffins into boxes that can hold up to 6 muffins each so you are dividing 231 divided by 6 so the answer is 38 full boxes and 3 muffins left in the last box ( I just took the test and that was the answer)

4(2a + 3) < 3(a - 1)
Answer:
-3
Step-by-step explanation:
4(2a +3)<3(a - 1)
8a +12 <3a - 3
8a - 3a <-3 - 12
5a<-15
a<15 :5
a<-3
Answer:
Step-by-step explanation:
4(2a+3) =3(a-1)
simplify
8a+12 =3a-3
-12 on the 12 and -3
8a=3a-15
add 15 to the 15 and 8
13=3a
always divide by the variable so 3 divide by 3 and 3 divide by 13

A. 4 real
OB. 4 real; 4 complex
C. 2 real; 2 complex
OD. 4 complex
Reset Selection
Answer:
D, it admits 4 complex roots
Step-by-step explanation:
Based on what you've written;
f(x) can be rewritten by adding the light terms together as;
f(x)=2x⁴-16x+1768.68
By graphing this function on an app, since i cannot possibly simplify this equation or use a calculator;
we observe that this function does not intersect the x-axis at any point, hence it does not admit any real roots.
So your answer must be D.
ps: Regardless if you forgot any x's in your equation and if f(x) was actually defined by,
f(x)=2x⁴-9.32x³+1772x²-16x+6
This equation also admits 4 complex roots and does not intersect the x-axis

Solve each proportion
Hello.
In order to solve a proportion, you should cross-multiply:
[tex]\displaystyle\frac{7}{x} =\frac{5}{9}[/tex]
Multiply 7 times 9 and 5 times x:
5x=63
Divide both sides by 5:
x=[tex]\displaystyle\frac{63}{5}[/tex]
Now let's solve the second proportion.
Multiply 8p times 6 and 12 times 15:
48p=180
Divide both sides by 48:
p=3.75

write an equation for the point 4,3
Answer:
y-3=3(x-4)
Step-by-step explanation:
Hi there!
We are given that a line intersects the points (4, 3), and (6, 9)
The slope of this line is 3
And we want to write an equation in point-slope form using (4, 3)
Point-slope form is written as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point
We already have one point of the equation filled out -- the [tex]y_1[/tex], which in this case, is 3;
Our current equation is:
[tex]y-3=m(x-x_1)[/tex] (n.b. I put m and [tex]x_1[/tex] as place holders)
Before we proceed though, let's label the values of the other things (m and [tex]x_1[/tex]) to avoid confusion:
[tex]x_1=4\\m=3[/tex]
Now we can substitute these into the equation:
y-3=3(x-4)
Hope this helps!

Given the arithmetic sequence : 52, a, b, 67 . Find the value of a * b
Answer:
a=57 b=62
Step-by-step explanation:
u⁰=52
u¹=a
u²=b
u³=67
Use the explicit relation given by:
u(n)=u⁰+nd
where n is any term and d is the common difference.
u³=u⁰+3d
67=52+3d
3d=67-52
d=15/3
d=5
a=52+5=57
b=a+5=62
67=b+52=62+5=67 (just to make sure of the answer)

Step-by-step explanation:
We can use the Pythagorean Theorem to find x.
Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
Where "a" and "b" represent the legs and "c" represents the hypotenuse of the right triangle.
Let's substitute the given lengths into the equation:
[tex]28^2+45^2=x^2\\784+2025=x^2\\x^2=2809[/tex]
Take the square root of both sides:
[tex]\sqrt{x^2}=\sqrt{2809}[/tex]
