Answer:

Step-by-step explanation:

Given that, the length of the chain is

L= 19m

And the mass of the chain is

M= 84kg

Work to raise the chains to a height of

H = 7m

Acceleration due to gravity

g = 9.8m/s²

Since the chain is 19m long and it has a mass of 84kg

Then, it mass/ length is 84/19

M/L = 4.42kg/m

So, it weight / length is mass / length × gravity

W/L = M/L × g

W/L = 4.42 × 9.8

W/L = 43.33 N/m

So, workdone can be calculated using

Work = ∫F∆x

Work = ∫(W/L)•xdx.

Work = ∫43.33x dx. From x = 0 to 7

Work = 43.33 ∫x dx.

Work = 43.33 x²/2. From x = 0 to 7

Work = 21.66 [x²] from x = 0 to 7

Work = 21.66 ( 7²-0²)

Work = 21.66 × 49

Work = 1061.5 Joule

The workdone to lift the chain to 7m is 1061.5 J

"When work is done to lift the chain to 7m is 1061.5 J. To understand the calculations, check below".

Given that, the length of the chain as per the question is:

L= 19m

And also the mass of the chain is

Then M= 84kg

Now Work to raise the chains to a height of

After that H = 7m

Acceleration due to gravity

Then g = 9.8m/s²

Since When the chain is 19m long and it has a mass of 84kg

Then, it mass/ length is 84/19

M/L = [tex]4.42kg/m[/tex]

After that, it weight / length is mass / length × gravity

W/L = M/L × g

W/L = 4.42 × 9.8

W/L = 43.33 N/m

Then, work done can be calculated using

Work is = ∫F∆x

Work is = ∫(W/L)•xdx.

Then Work = ∫43.33x dx. From x = 0 to 7

After that Work = 43.33 ∫x dx.

Now Work = 43.33 x²/2. From x = 0 to 7

Work is = 21.66 [x²] from x = 0 to 7

Work is = 21.66 ( 7²-0²)

Then Work = 21.66 × 49

Hence Work = 1061.5 Joule

Therefore, The work done to lift the chain to 7m is 1061.5 J

Answer:

43.13 yd squared

Step-by-step explanation:

This is a figure composed of a semicircle and a right triangle.

Triangle:

The area of a triangle is denoted by A = (1/2) * B * h, where b is the base and h is the height. Here, the base is actually also the radius of the semicircle, which is 4. The height is 9. Plug these in: A = (1/2) * 4 * 9 = 36/2 = 18 yd squared.

Semicircle:

The area of a semicircle is denoted by A = [tex](1/2)\pi r^{2}[/tex], where r is the radius. Here the radius is 4. So: A = [tex](1/2)\pi *4^{2}=8\pi[/tex] ≈ 25.13 yd squared.

Adding these up: 18 + 25.13 = 43.13 yd squared

Hope this helps!

Answer:

Answer:

The distance the tornado traveled was approximately 205 miles.

Step-by-step explanation:

The equation representing the relationship between the wind speed (in miles per hour) and the distance the tornado travels (in miles) is:

[tex]s=93\log d+65[/tex]

Compute the value of d for s = 280 as follows:

        [tex]s=93\log d+65[/tex]

     [tex]280=93\log d+65[/tex]

[tex]93\log d=280-65\\93\log d=215[/tex]

   [tex]\log d=2.312\\[/tex]

        [tex]d=10^{2.312}\\d=205.035\\d\approx 205[/tex]

Thus, the distance the tornado traveled was approximately 205 miles.

Final answer:

The process of finding the surface area of a rectangular prism is similar to finding the surface area of a triangular prism. Both involve drawing a net and adding the areas of the faces. However, the formulas used are different because the shapes have different types of faces.

Explanation:

For both prisms, you can draw a net to help you find the areas of the faces. Add the areas together to find the surface area. A rectangular prism has only rectangular faces, and you use the formula bh to find area. A triangular prism has triangular and rectangular faces, and you use the area formula bh for rectangular faces and the area formula 1/2bh for triangular faces.

The correct option is D (-∞,-3)∪(-1,1)

Step-by-step explanation:

Given,

[tex]\frac{x^{2}-1 }{3x+9}[/tex] ≤ 0

To find the solution.

The solution could be found if

[tex]x^{2} -1[/tex] ≤ 0           and

3x+9 ≠ 0 [if the denominator is 0, it gives ∞ as solution]

Now,

[tex]x^{2} -1[/tex] ≤ 0

or, (x+1)(x-1) ≤0

or, x ≤1 and x≤-1

Both of the above condition holds is x≤1

Again,

3x+9≠0

or, x≠-3

All the conditions gold for the values (-∞,-3)∪(-1,1)

Hence the correct option is D.

Answer:

y = 2x + 1

y = 4x - 1

Step-by-step explanation:

You haven't mentioned the question so, unfortunately I can't give you the answer.

The correct answer is that the system of equations has no solution.

To determine the solution to the system of equations, we need to compare the two equations

1. [tex]\( y = 2x + 1 \)[/tex]

2. [tex]\( y = 4x - 1 \)[/tex]

For a system of equations to have a solution, both equations must be satisfied simultaneously. This means that the values of [tex]\( x \) and \( y \)[/tex] that satisfy one equation must also satisfy the other equation.

Let's analyze the equations. Both equations are in slope-intercept form, [tex]\( y = mx + b \)[/tex], where m is the slope and b  is the y-intercept.

For the first equation, the slope is 2 and the y-intercept is 1. For the second equation, the slope is 4 and the y-intercept is -1 .

Since the slopes of the two lines are different (2 for the first line and 4 for the second line), the lines are not parallel. However, the y-intercepts are different as well (1 for the first line and -1 for the second line). This means that the lines are not the same line and they will never intersect because two lines with different slopes and different y-intercepts cannot meet.

Therefore, there is no point [tex]\( (x, y) \)[/tex] that satisfies both equations simultaneously, and the system of equations has no solution. This is an example of a system of linear equations that is inconsistent.

In conclusion, the system of equations given by [tex]\( y = 2x + 1 \)[/tex] and [tex]\( y = 4x - 1 \)[/tex] has no solution because the lines represented by these equations are neither parallel nor do they intersect.

Step-by-step explanation:

Please see the attached picture for full solution.

The total surface area of the cone is 7π square yards.

To find the total surface area of the cone, we need to find the lateral surface area and add it to the base area.

The lateral surface area of a cone is given by the formula πrℓ, where r is the radius and ℓ is the slant height.

In this case, the lateral surface area is 62.8 square yards and the slant height is 2 yards.

So, the lateral surface area of the cone is π(2)(2) = 4π square yards.

The base area of a cone is given by the formula πr^2, where r is the radius.

Since the slant height is given, we can use the Pythagorean theorem to find the radius. The radius is the hypotenuse of a right triangle with the slant height as one of the legs and the height of the cone as the other leg.

Using the Pythagorean theorem, we have r^2 = (2)^2 - (1)^2 = 4 - 1 = 3.

Therefore, the radius is √3 yards.

The base area of the cone is then π(√3)^2 = 3π square yards.

The total surface area of the cone is the sum of the lateral surface area and the base area, 4π + 3π = 7π square yards.

Answer:

1,350

Step-by-step explanation:

To find Surface Area you need to area of all the sides and add them

So to find one side of the cube you do L x H

So 15 x 15 = 225

Since all the sides of the cube are the same, you don't need to figure out the area of the other sides.

225 x 6 sides = 1,350

In the given diagram

Each small box along X axis = 2 unit

Each small Box along Y axis = 2 unit

For rectangle:

Length = 16 unit

Width = 16 unit

For triangle 1

Base = 8 unit

Height = 6 unit

For triangle 2

Base = 8 unit

Height = 4 unit

For triangle 3

Base = 16 unit

Height = 12 unit

Formula

Area of the trapezoid is

[tex]A = R -T_{1} -T_{2} -T_{3}[/tex]

Where, [tex]A[/tex] be the area of the trapezoid

[tex]R[/tex] be the area of the rectangle

[tex]T_{1} ,T_{2} ,T_{3}[/tex] be the area of the triangle 1, 2 and 3 respectively.

[tex]R = lb[/tex] where, l be length and b the width

[tex]T_{1} = \frac{1}{2} bh[/tex], where, b be the base and h be the height

Now,

Taking, l = 16 and b = 16 we get,

[tex]R = (16)(16)[/tex] = 256 sq unit

For Triangle 1

Taking, b = 8 and h = 6 we get,

[tex]T_{1} = \frac{1}{2}(8)(6)[/tex] sq unit

[tex]T_{1} = 24[/tex] sq unit

For Triangle 2

Taking, b = 8 and h = 4 we get,

[tex]T_{2} = \frac{1}{2}(8)(4)[/tex] sq unit

[tex]T_{2} = 16[/tex] sq unit

For Triangle 3

Taking, b = 16 and h = 12 we get,

[tex]T_{3} = \frac{1}{2}(16)(12)[/tex] sq unit

[tex]T_{3} = 96[/tex] sq unit

Therefore,

The area of the trapezoid is = 256-24-16-96 sq unit = 120 sq unit

Hence,

Area of rectangle =256 square units

Area of triangle 1 = 24 square units

Area of triangle 2 = 16 square units

Area of triangle 3 = 96 square units

Area of trapezoid = 120 square units

The solution of a system of equations is (3,0).

A system of linear equations is a collection of one or more linear equations involving the same variables in mathematics. The system of linear equations appears to have a solution of (3, 0).

A linear equation is one in which the variable's maximum power is always 1.  The degree of the linear equation is always equal to one.

If a system of linear equations has two equations and a graph of these two equations intersect each other at (a,b), then the point (a,b) is the solution of that system of equations.

Since, the solution of a system of equations is (3,0), therefore on a coordinate plane, 2 lines intersect at (3, 0).

Therefore, the solution of a system of equations is (3,0).
