Answer:

The train travels at 66 miles per hour.

Step-by-step explanation:

Given that:

Time taken by train = 8 hours

Distance covered by train in 8 hours = 528 miles

Unit rate is defined by the distance travelled by train in one hour.

Therefore, we will divide the total time taken by train to distance covered by train in that time.

Unit rate = [tex]\frac{Distance\ travelled}{Time\ taken}[/tex]

Unit rate = [tex]\frac{528}{8}[/tex]

Unit rate = 66 miles per hour

Hence,

The train travels at 66 miles per hour.

Answer:

[tex]\mathbf{\iint _D y^2 dA= \dfrac{22}{3}}[/tex]

Step-by-step explanation:

From the image attached below;

We need to calculate the limits of x and y to find the double integral

We will notice that y varies from 1 to 2

The line equation for (0,1),(1,2) is:

[tex]y-1 = \dfrac{2-1}{1-0}(x-0)[/tex]

y - 1 = x

The line equtaion for (1,2),(4,1) is:

[tex]y-2 = \dfrac{1-2}{4-1}(x-1) \\ \\ y-2 = -\dfrac{1}{3}(x-1)[/tex]

-3(y-2) = (x -1)

-3y + 6 = x - 1

-x = 3y - 6 - 1

-x = 3y  - 7

x = -3y + 7

This implies that x varies from y - 1 to -3y + 7

Now, the region D = {(x,y) | 1 ≤ y ≤ 2, y - 1 ≤ x ≤ -3y + 7}

The double integral can now be calculated as:

[tex]\iint _D y^2 dA= \int ^2_1 \int ^{-3y +7}_{y-1} \ 2y ^2 \ dx \ dy[/tex]

[tex]\iint _D y^2 dA= \int ^2_1 \bigg[ 2xy ^2 \bigg]^{-3y+7}_{y-1} \ dy[/tex]

[tex]\iint _D y^2 dA= \int ^2_1 \bigg[2(-3y+7)y^2-2(y-1)y^2 \bigg ] \ dy[/tex]

[tex]\iint _D y^2 dA= \int ^2_1 \bigg[-6y^3 +14y^2 -2y^3 +2y^2 \bigg ] \ dy[/tex]

[tex]\iint _D y^2 dA= \int ^2_1 \bigg[-8y^3 +16y^2 \bigg ] \ dy[/tex]

[tex]\iint _D y^2 dA= \bigg[-8(\dfrac{y^4}{4}) +16(\dfrac{y^3}{3})\bigg ] ^2_1[/tex]

[tex]\iint _D y^2 dA= \bigg[-8(\dfrac{16}{4}-\dfrac{1}{4}) +16(\dfrac{8}{3}-\dfrac{1}{3})\bigg ][/tex]

[tex]\iint _D y^2 dA= \bigg[-8(\dfrac{15}{4}) +16(\dfrac{7}{3})\bigg ][/tex]

[tex]\iint _D y^2 dA= -30 + \dfrac{112}{3}[/tex]

[tex]\iint _D y^2 dA= \dfrac{-90+112}{3}[/tex]

[tex]\mathbf{\iint _D y^2 dA= \dfrac{22}{3}}[/tex]

To answer this question, we need, first get the equations for the lines that enclosed the surface, and integrate according to the limits these equations give.

The solution is:

A = 22/3 square units

Let´s call points:

P ( 0 , 1 )    Q ( 1 , 2 ) and R ( 4 , 1 )

The equation for the line between P and R is:

y = 1

The equation for the line between P and Q is:

Slope-intercept equation is  y = m×x + b

The slope   m₁ = ( 2 - 1 ) / ( 1 - 0 )    m₁ = 1

and the line passes over the point  x = 0  y = 1   ; then

1 = 0 +b           b = 1

y = x + 1            ⇒    x = y - 1  

The equation  for the line between Q and R is:

m₂ = ( 1 - 2 ) / ( 4 - 1)    m₂ = - 1/3

y = ( -1/3)× x + b

when x = 1    y = 2

2 = ( - 1/3)×(1) + b

2 + 1/3 = b

b = 7/3

y = - (x/3) + 7/3            ⇒  x = 7 - 3×y

The double  integral becomes:

A = 2×∫∫ y² dx dy          ⇒   A = 2 ×∫₁² y²dy ∫dx  | (y - 1 ) y ( 7 - 3y)

A = 2 ×∫₁² y²dy  × x |  ( y - 1 ) y ( 7 - 3y)

A = 2 ×∫₁² y²dy  × [ 7 - 3×y - ( y - 1 )]

A = 2 ×∫₁² y²dy  × (8 - 4×y )      ⇒     A = 2 ×∫₁² (8×y² - 4×y³ ) dy

A = 2 × [ (8/3)×y³ - y⁴ | ₁²

A = 2 × [ 64/3 - 16 - (8/3) + 1 ]

A = 2  × ( 56/3 - 15 )

A = 2  × ( 56 - 45 /3)

A = 2 × 11/3

A = 22/3 square units

Answer:

$3.90

Step-by-step explanation:

its B

The price of the ticket at which the student councils will maximize the profit is $3.90.

Option B is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of students = 480

Lowest ticket price = $3

Ticket price = $4.20

This means,

4.20 - 3 = 1.20

There is an increase of $1.20 which is 0.20 x 6 = $1.20.

The number of students who attended when the ticket price is $4.20.

= 480 - (6 x 20)

= 480 - 120

= 360

Profit:

= 360 x 4.20

= $1512

Ticket price = $3.90

This means,

3.90 - 3 = 0.90

There is an increase of $0.90 which is 0.20 x 4.5 = $0.90.

The number of students who attended when the ticket price is $3.90.

= 480 - (4.5 x 20)

= 480 - 90

= 390

Profit:

= 390 x 3.90

= $1521

Now,

Ticket price = $3.50

This means,

3.50 - 3 = 0.50

There is an increase of $0.50 which is 0.20 x 2.5 = $0.50.

The number of students who attended when the ticket price is $3.50.

= 480 - (2.5 x 20)

= 480 - 50

= 430

Profit:

= 430 x 3.50

= $1505

Now,

Ticket price = $4.00

This means,

4 - 3 = 1

There is an increase of $1 which is 0.20 x 5 = $1.

The number of students who attended when the ticket price is $4.20.

= 480 - (5 x 20)

= 480 - 100

= 380

Profit:

= 380 x 4.20

= $1520

We see that,

The profit is highest when the ticket price is $3.90.

Thus,

$4 ticket price will maximize the student council's profit.

Answer:

Average rate of change=22

Step-by-step explanation:

We need to find the average rate of change of the equation: [tex]y=4x^2-10x+2[/tex]between f(3) and f(5).

The formula used to find average rate of change is: [tex]Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}[/tex]

In the given question we have a=3 and b =5

Finding f(a) i.e f(3)

[tex]f(3)=4(3)^2-10(3)+2\\f(3)=4(9)-30+2\\f(3)=36-30+2\\f(3)=8[/tex]

Finding f(b0 i.e f(5)

[tex]f(5)=4(5)^2-10(5)+2\\f(5)=4(25)-50+2\\f(5)=100-50+2\\f(5)=52[/tex]

Putting values of f(3)=8 and f(5)=52 to find average rate of change

[tex]Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}\\Average \ rate \ of \ change=\frac{52-8}{5-3}\\Average \ rate \ of \ change=\frac{44}{2}\\Average \ rate \ of \ change=22[/tex]

Step-by-step explanation:

Lauren paid $30 for the jacket on sale.

Percentage of any number is calculated by dividing the number with the whole and then multiplying the result with 100.

Similarly the opposite steps can be used to find the original number out of the percentage.

So percentage is the ratio or number which can be expressed as a fraction of 100 or in simple terms, percentage is the part per 100.

The symbol we use to denote percentage is %.

Lauren bought a jacket that was on sale.

Original price of the jacket = $75

Amount Lauren paid is the 40% of the original price $75.

Actual price paid = 40% × 75

= (40/100) × 75

= 0.4 × 75

= 30

That is the actual price is $30.

Hence, if Lauren paid 40% of the original price $75, then the amount Lauren paid for the jacket is $30.

Answer:

a. The new number created is 265,134.

b. The new number created is 625,314.

c. The new number created is 652,314.

d. The new number created is 462,513.

e. The new number created is 253,416.

Step-by-step explanation:

Note: The first question is not correctly and fully stated. It is therefore restated as the questions are answered as follows:

a. Move the 2 so it is worth 10 as much.

From 625,134, the 2 implies 20,000.

If we move the 2 so it is worth 10 as much, it implies that 20,000 is multiplied by 10 and the answer is as follows:

20,000 * 10 = 200,000

The answer implies that 2 becomes the first number and the new number created from 625,134 is as follows:

The new number created is 265,134.

b. Move the 3 so it is worth 10 times as much.

From 625,134, the 3 implies 30.

If we move the 3 so it is worth 10 as much, it implies that 30 is multiplied by 10 and the answer is as follows:

30 * 10 = 300

The answer implies that 3 becomes the fourth number and the new number created from 625,134 is as follows:

The new number created is 625,314.

c. Move the 5 so it is worth 50,000.

This implies that 5 becomes the second number and the new number created from 625,134 is as follows:

The new number created is 652,314.

d. Move the 4 so its value changes to 4 X 100,000

This implies that 4 is now 400,000 and it now becomes the first number. The new number created from 625,134 is as follows:

The new number created is 462,513.

e. Move the 1 and the 6 so that the sum of their values is 16.

This implies the one becoms 10 and the 6 becomes just 6.

As a result, this implies that the 1 now becomes the fifth number and the 6 now become the last number. The new number created from 625,134 is now as follows:

The new number created is 253,416.

Answer:

Length = 162 feet and Width = 108 feet.

Step-by-step explanation:

The area of a 2D form is the amount of space within its perimeter. The area of this region will cover is 26,244 feet².

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

A four-sided figure covers the maximum area when the length of its four sides is equal. Therefore, the length and the width of the region will be equal. Thus, we can write the length of the fence as,

4x = 648 feet

x = 648/4 feet

x = 162 feet

Now, the area this region will cover is,

Area = 162 feet x 162 feet

        = 26,244 feet²

Hence, the area of this region will cover is 26,244 feet².
