Select the correct answer from the drop-down menu. the sound level, , in decibels (db), of a sound with an intensity of i is calculated in relation to the threshold of human hearing, , by this equation. the threshold of human hearing is . the sound level of a jet plane is approximately 140 db. the intensity of the sound of a jet plane is approximately .
If the sound level of a jet plane is approximately 140 db, the intensity of the sound of a jet plane is approximate 100dB
Functions and valuesThe sound level of a jet plane is expressed according tothe expression given as:
β = 10log(I/I0)
Given the folowing parameters
β = 140dB
I0 = 10^-12 W/m²
Required
Intensity "I"
Substitute
140 =10log(I/10^-12)
14 = log(I/10^-12)
10^14 = I/10^-12
I = 10^14 * 10^-12
I = 10^2
I = 100dB
Hence if the sound level of a jet plane is approximately 140 db, the intensity of the sound of a jet plane is approximate 100dB

Bill ran 10 laps around the high school track in 12 minutes how many laps can be run in 45 minutes
Answer:
37.5 laps
Step-by-step explanation:
If we assume that Bill can run at the same speed for 45 minutes, the number of laps will be proportional to the time.
laps/time = 10 laps/(12 minutes) = n laps/(45 minutes)
n laps = (10 laps)(45/12) = 37.5 laps . . . . . multiply by 45 minutes
Bill can run 37.5 laps in 45 minutes.

A satellite is orbiting Earth at an orbital radius of 7. 3 x 10^4m. What is its velocity in terms of G and the mass of Earth,mp?
The velocity of the satellite in orbit around Earth is approximately 73.8856 x 10³m/s.
The velocity of a satellite in orbit around Earth can be found using the formula:
v = √(G * mp / r)
where G is the gravitational constant [tex](6.67 \times 10^{-11} Nm^2/kg^2)[/tex], mp is the mass of Earth ([tex]5.97 \times 10^{24}[/tex] kg), and r is the orbital radius of the satellite ([tex]7.3 \times 10^4[/tex] m).
Substituting the given values into the formula, we get:
[tex]v = \sqrt{(6.67 * 10^{-11} * 5.97 *10^{24} /(7.3*10^4)}[/tex]
v ≈ 73.8856 x 10³ m/s
Therefore, the velocity of the satellite in orbit around Earth is approximately 73.8856 x 10³m/s.

Step 2: Add 9 to both sides
[tex]1/4x - 9 = 6[/tex]
[tex]1/4x - 9 + 9= 6+ 9[/tex]
[tex]1/4x = 15[/tex]

Let x² + 15x = 49 . What values make an equivalent number sentence after completing the square? Enter your answers in the boxes.
x² + 15x + = [ ]
Answer:
Step-by-step explanation:
15/2 = 7.5 and (7.5)^2 = 56.25 so
x^2 + 15x + 56.25 = 49 + 56.25
x^2 + 15x + 56.25 = 105.25.
Answer:
[tex]x^2+15x+\boxed{\dfrac{225}{4}}=\boxed{\dfrac{421}{4}}[/tex]
[tex]x^2+15x+\boxed{56.25}=\boxed{105.25}[/tex]
Step-by-step explanation:
General form of a quadratic equation: [tex]ax^2+bx+c[/tex]
When completing the square, first add the number that is the square of half of [tex]b[/tex].
Given equation: [tex]x^2+15x=49[/tex]
Therefore, [tex]b=15[/tex]
[tex]\implies \left(\dfrac{b}{2}\right)^2=\left(\dfrac{15}{2}\right)^2=\dfrac{225}{4}[/tex]
So we need to add 225/4 to both sides of the equation:
[tex]\implies x^2+15x+\dfrac{225}{4}=49+\dfrac{225}{4}[/tex]
[tex]\implies x^2+15x+\boxed{\dfrac{225}{4}}=\boxed{\dfrac{421}{4}}[/tex]
In decimal form:
[tex]\implies x^2+15x+\boxed{56.25}=\boxed{105.25}[/tex]
To finish completing the square,
factor the left side of the equation:
[tex]\implies \left(x+\dfrac{15}{2}\right)^2=\dfrac{421}{4}[/tex]
Finally, subtract 421/4 from both sides:
[tex]\implies \left(x+\dfrac{15}{2}\right)^2-\dfrac{421}{4}=0[/tex]
In decimal form:
[tex]\implies (x+7.5)^2-105.25=0[/tex]

Doing some review on PEMDAS. I just need help to know if I am on the right track with this problem.
Answer:
The order in which you evaluated the expression was a bit incorrect but the outcome either way was 78. In some cases if you evaluate the expression incorrectly or not in order will result in you getting the wrong answer. If you want to see how to evaluate it correctly just look below.
Step-by-step explanation:
PEMDAS stands for
Parenthesis
Exponents
Multiplication and Division ( left to right )
Addition and Subtraction ( left to right )
And it basically tells us the order in which you are suppose to evaluate a mathematical expression.
It appears the expression you are given is 4² + ( 1 × 5 + 7² ) + 8
First we would do the operation inside of the parenthesis
so we have ( 1 × 5 + 7² )
Exponents come before multiplying and addition so first evaluate the exponent, 7² = 49
we now have ( 1 × 5 + 49 )
we next do the multiplication
( 5 + 49 )
Finally we do the addition
5 + 49 = 54.
We then replace the expression ( 1 × 5 + 7² ) with 54 as we just evaluated everything in the parenthesis
we get 4² + 54 + 8
So we just did the parenthesis and next is exponents so lets evaluate the exponents, 4² = 16
16 + 54 + 8
Next in PEMDAS is multiplication and division. There is none so we go to the next step.
We now do the addition and subtraction. ( going left to right )
16 + 54 + 8
first add 16 and 54
70 + 8
finally add 70 and 8
= 78
Notes:
For parenthesis you evaluate everything inside of the parenthesis before you remove the parenthesis
For multiplcation and division, you must evaluate in order going left to right, not doing so can result in a wrong answer.

What is the formula for finding the slope of a line? Circle your choice.
Answer:
B
Step-by-step explanation:
to find the slope of a line you use slope intercept form
Option (b) is correct. The formula m = (y₂ - y₁)/(x₂ - x₁) is used to find the slope of the line.
What is slope of the line?In Mathematics, "a slope of a line is the change in y coordinate with respect to the change in x coordinate".
According to the question,
Equation of the line using slope intercept form is y = mx + c where 'x, y' are variable and 'm' is the slope of the line and 'c' is constant.
To find the slope of the line m = (y₂ - y₁)/(x₂ - x₁).
Hence, the option (B) m = (y₂ - y₁)/(x₂ - x₁) is correct.
