If the sound level of a jet plane is approximately 140 db, the intensity of the sound of a jet plane is approximate 100dB

The 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

Answer:

your question is not quite clear.

are you trying to ask ask this " Are negative 4 minus 6 less than 50 ?

if so then it can also be translated mathematically as " - 4 - 6 = 50

then the answer is YES.

Step-by-step explanation:

because - 4 - 6 is -10

- 10 is less than 50

Because in the number line

e.g -10, -9, -8 , -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, and so on...

you can see that -10 is way lesser than 50.

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.

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.

If 2 chords intersect then the product of the parts of one chord is equal to the product of the parts of the other chord , that is

4x = 2 × 12 = 24 ( divide both sides by 4 )

x = 6

Answer:

Step-by-step explanation:

Given :

x = -6

-7x + 6y = -18 ... i)

Putting the value of x in equation ...i)

=> -7 (-6) + 6y = -18

=> 42 + 6y = -18

=> 6y = -18 -42

=> 6y = - 60

=> y = -60/6

=> y = -10

The value of y = -10 and x = -6

Answer:

x= 4, y=6

Step-by-step explanation:

9x-9y = -18

9x=-18+9y

x=-2+y

-6(-2+y) + 9y = 6

-12-6y+9y=6

3y=18

Answer:

14.9g + 9.5c

Step-by-step explanation:

g stands for $ earned training & c stands for $ earned working with customers

Anthony trained for 8.5 hours so, 8.5 hours x g $ earned at training = 8.5g

He worked with customers for 4.3 hours, so 4.3 hours x c $ earned with customers = 4.3c

Anthony's total $ earned is 8.5g + 4.3c

Madison trained for 6.4 hours so, 6.4 hours x g $ earned at training = 6.4g

She worked with customers for 5.2 hours, so 5.2 x c $ eared with customers = 5.2c

Madison's total $ earned is 6.4g + 5.2c

Anthony  8.5g  +  4.3c

Madison  6.4g  +  5.2c

If you add both their $ earned training, you get 14.9g

If you add both their $ earned with customers, you get 9.5c

To total what they both earn  it would be 14.9g + 9.5c

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.

Answer:

21°C

Step-by-step explanation:

If the temperature was -5° in the morning and 16° in the morning, then that means there was an increase in temperature. To find the exact change in temperature, we need to find what plus -5 would be equal to 16.

-5 + x = 16

-5+5 + x = 16+5

x = 21

From this, we can see that the change in temperature was 21°C.

Polynomial are expression that have a leading degree of 3. Given the following expression

Sum = –yz^2 – 3z^2 – 4y^4.

One of the polynomial = y – 4yz^2 – 3

The other polynomial

Let the unknown polynomial be "a" such that:

a =  –yz^2 – 3z^2 – 4y^4 - (y – 4yz^2 – 3)

Expand

a =  –yz^2 – 3z^2 – 4y^4 - y + 4yz^2 + 3

a = 3yz^2 – 3z^2 – 4y^4 - y + 3

Step-by-step explanation: got it right on edge

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.

Using the permutation formula, it is found that there are 840 possible arrangements of the 4 trophies.

The problem says the word "arrangements", which implies that the order matters, hence the permutation formula is used to solve this question.

The number of possible permutations of x elements from a set of n elements is given by:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this problem, 4 elements from a set of 7 are arranged, hence:
