Joule per meter second is the unit of measurement for momentum flux or power per unit area. It is commonly used in physics and engineering to quantify the rate of energy transfer or momentum flow per unit area.

Joule per meter second (J/m^2s) is not the correct unit for momentum flux or power per unit area. The correct unit for momentum flux is Newton per square meter (N/m^2), also known as Pascal (Pa), while the correct unit for power per unit area is watt per square meter (W/m^2). The joule per meter second (J/m^2s) is actually the unit for volumetric energy dissipation rate, which measures the rate at which energy is being dissipated within a fluid volume per unit volume. It is used in the study of fluid dynamics and turbulence.

Given:

Write and evaluate the definite integral that represents the volume of the solid formed by revolving the region about the x-axis.

y = x^4, y = x^7

In addition, we must identify if the axis of revolution is vertical or horizontal.

In this case, the axis of revolution is on the x-axis, when y=0

The axis of revolution is Horizontal.

Select the method to find the volume. We select the Washer Method:

\(V = pi*\int\limits^b_a {(R(x))^2-(r(x))^2} \, dx\)

From the image uploaded:

Step-by-step explanation:

Let x be the total number of students who average watching more than 4 hours of TV each day.

We have been given that Timpony School District surveyed a random sample of 60 middle school students about the amount of time they watch TV. Of the students surveyed, 14 average watching more than 4 hours of TV each day.  

So the probability of a student watching more than 4 hours of TV each day will be

To find the estimated number of students, who watch the TV more than 4 hours each day, we will use relative probability as it is the ratio of the occurrence of a singular event and the total number of outcomes.

So we can set a proportion as:

Upon dividing both sides of our equation by 1143 we will get,

Therefore, approximately 267 students of Timpony School District middle school average watching more than 4 hours of TV each day.

Using the linear approximating polynomial, e^(-0.7) is approximately 1.7, and using the quadratic approximating polynomial, e^(-0.7) is approximately 1.945.

To find the linear approximating polynomial, we need the first-degree Taylor polynomial centered at a = 0. The linear approximating polynomial is given by p_1(x) = f(a) + f'(a)(x - a), where f(x) = e^(-x).

First, we find f(a) and f'(a):

f(a) = f(0) = e^0 = 1

f'(a) = f'(0) = -e^0 = -1

Substituting these values into the linear approximating polynomial, we get:

p_1(x) = 1 - 1(x - 0) = 1 - x

b. To find the quadratic approximating polynomial, we need the second-degree Taylor polynomial centered at a = 0. The quadratic approximating polynomial is given by p_2(x) = f(a) + f'(a)(x - a) + (1/2)f''(a)(x - a)^2.

First, we find f''(a):

f''(a) = f''(0) = -f'(0) = -(-1) = 1

Substituting all the values into the quadratic approximating polynomial, we get:

p_2(x) = 1 - 1(x - 0) + (1/2)(1)(x - 0)^2

= 1 - x + (1/2)x^2

= 1 - x + (1/2)x^2

c. Using the linear approximating polynomial p_1(x) = 1 - x, we can approximate e^(-0.7) by substituting x = -0.7:

p_1(-0.7) = 1 - (-0.7) = 1 + 0.7 = 1.7

Using the quadratic approximating polynomial p_2(x) = 1 - x + (1/2)x^2, we can approximate e^(-0.7) by substituting x = -0.7:

p_2(-0.7) = 1 - (-0.7) + (1/2)(-0.7)^2 = 1 + 0.7 + (1/2)(0.49) = 1 + 0.7 + 0.245 = 1.945

The relative intensity of the air-raid siren is 10^3 times greater than that of the jet engine noise.

To find how many times greater the relative intensity of the air-raid siren is compared to the jet engine noise, we need to compare the decibel values and use the equation L = 10 log R.

Let's assume the relative intensity of the jet engine noise is R_jet and the relative intensity of the air-raid siren is R_siren.

We are given:

L_jet = 120 decibels

L_siren = 150 decibels

Using the equation L = 10 log R, we can rewrite it as R = 10^(L/10).

For the jet engine noise:

R_jet = 10^(L_jet/10) = 10^(120/10) = 10^12

For the air-raid siren:

R_siren = 10^(L_siren/10) = 10^(150/10) = 10^15

To find the ratio of the relative intensities, we divide R_siren by R_jet:

Ratio = R_siren / R_jet = (10^15) / (10^12) = 10^(15-12) = 10^3

Given the real number 0.017.

The proper way for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

Next, we would switch the decimal point to the left of the decimal point until there is just one non-zero integer.

0.017 ---> 001.7

Second, we must count how many places we moved the decimal point, in this case it's 2 places. This will be the b exponent.

As we moved the decimal two places to the right, then b is negative.

b= -2

Step-by-step explanation:

a1 = 7

nth term is -175

common difference d= 0-7 = -7 or -7 - 0 = -7

nth term = first term + ( n-1) * common difference

-175 = 7 + ( n - 1 ) * (- 7)

-175 = 7 - 7n + 7

-175 = 14 - 7n

-175-14 = -7n

-189 = - 7n

Answer:

175 + 15x = 400

Step-by-step explanation: X= the pack of cards.

Jenna will have to buy 22 card packets to have more than 400 cards in the collection.

An inequality is used to compare two or more expressions or numbers.

For example -

2x > 4y + 3

x + y > 3

x - y < 6

Given is that Jenna has a collection of trading cards. She started her collection with 175 cards. She buys packs of cards that contain 15 cards each

Assume that she will have to buy {x} packets of cards to have over 400 cards. Then, we can write the inequality as -

400 < 175 + 15x

15x > 325

x > 325/15

x > 65/3

x > 21.8

x > 22 {approx.}

Therefore, Jenna will have to buy 22 card packets to have more than 400 cards in the collection.

The average rate of change from year 2 to year 10 is approximately 6.9 inches per year.

Let's first calculate the height at year 2 and year 10 using the given function:

For year 2:

r = 2

h = -0.2 + 6.9 * 2 + 16

h = -0.2 + 13.8 + 16

h = 29.6 inches

For year 10:

r = 10

h = -0.2 + 6.9 * 10 + 16

h = -0.2 + 69 + 16

h = 84.8 inches

Average rate of change = (Change in height) / (Change in time)

Change in height = h(year 10) - h(year 2) = 84.8 - 29.6 = 55.2 inches

Change in time = year 10 - year 2 = 10 - 2 = 8 years

Average rate of change = (55.2 inches) / (8 years)

Average rate of change ≈ 6.9 inches per year

To find the homogeneous and particular solutions of the non-homogeneous differential equation y" + 3y - 4y = e, we can use the method of undetermined coefficients. The correct answer is option (e).

To solve the non-homogeneous differential equation, we first find the homogeneous solution by setting the right-hand side (e) to 0. The homogeneous equation becomes y" + 3y - 4y = 0, which can be rewritten as y" + 3y - 4y = 0. Solving this homogeneous equation yields the homogeneous solution yh = c₁y₁ + c₂y₂, where c₁ and c₂ are arbitrary constants, and y₁ and y₂ are linearly independent solutions.

Next, we need to find a particular solution that satisfies the non-homogeneous equation y" + 3y - 4y = e. We substitute this particular solution into the non-homogeneous equation and solve for the constants c₁ and c₂. Therefore, the correct answer is option (e), where the homogeneous solution is yh = c₁y₁ + c₂y₂ and the particular solution is y = cy₁ + c₂y₂.

 √2/2

Step-by-step explanation:

Factor 1296 into its prime factors

           1296 = 24 • 34 

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

Factors which will be extracted are :

           1296 = 24 • 34 

No factors remain inside the root !!

To complete this part of the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :

           36 = 22 • 32 

At the end of this step the partly simplified SQRT looks like this:

         36 √(x¹⁶y¹²)

STEP2:Simplify the Variable part of the SQRT

Rules for simplifing variables which may be raised to a power:

   (1) variables with no exponent stay inside the radical

(2) variables raised to power 1 or (-1) stay inside the radical

   (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:

      √(x⁸)=x⁴

     √(x^-6)=x^-3

 Applying these rules to our case we find out that

      SQRT(x¹⁶y¹²) = x⁸y⁶

Combine both simplifications

      sqrt (1296x¹⁶y¹²) =  36 x⁸y⁶

Simplified Root : 36 x⁸y⁶

Brei owes her mom $19.80 for the phone call.

To calculate how much Brei owes her mom for the phone call, let's break down the call into two time periods: before 8:00 a.m. and after 8:00 a.m.

Before 8:00 a.m.:

The call started at 7:00 a.m. and ended at 8:00 a.m., making it a duration of 1 hour (60 minutes).

The cost for the first minute is $0.35, and for the subsequent minutes, it's $0.20 per minute. So for the remaining 59 minutes, the cost is:

59 minutes * $0.20/minute = $11.80

The total cost for the call before 8:00 a.m. is:

$0.35 (first minute) + $11.80 (remaining minutes) = $12.15

After 8:00 a.m.:

The call continued from 8:00 a.m. to 8:30 a.m., which is a duration of 30 minutes.

The cost for the first minute is $0.40, and for the subsequent minutes, it's $0.25 per minute. So for the remaining 29 minutes, the cost is:

29 minutes * $0.25/minute = $7.25

The total cost for the call after 8:00 a.m. is:

$0.40 (first minute) + $7.25 (remaining minutes) = $7.65

To find the total cost for the entire call, we sum up the costs from both time periods:

$12.15 (before 8:00 a.m.) + $7.65 (after 8:00 a.m.) = $19.80
