One of the two conditions for equilibrium states that the sum of the torques around every possible center of rotation must be equal to zero. Does this mean that when you analyze a body in equilibrium

Step-by-step explanation:

One of the two conditions for equilibrium states that the sum of the torques around every possible center of rotation must be equal to zero. Does this mean that when you analyze a body in equilibrium

There are 2 conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium).

Torque is the expression of a rotational or twisting force. The engines in vehicles rotate about an axis, thus creating torque.

One of the two conditions for equilibrium states that the sum of the torques around every possible center of rotation must be equal to zero.

When a body or a system is in equilibrium, there is no net tendency to change.

In mechanics, equilibrium has to do with the forces acting on a body. When no force is acting to make a body move in a line, the body is in translational equilibrium; when no force is acting to make the body turn, the body is in rotational equilibrium.

There are 2 conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium).

These two conditions must be simultaneously satisfied in equilibrium.

Answer:

0.125

Step-by-step explanation:

This is a standard calculus question. If you search out L'Hopital's Rule you will find that there are only Calculus examples present. If you use calculus, the answer comes to 1/8. The only way I can think of doing this without the use of Calculus is to let x = something very small -- say x = 0.0001 That approaches 0, but it is not quite = to 0.

So let's try it.

16 + 0.00001  = 16.00001

sqrt(16.0001) = 4.00000125

Now subtract 4

4.00000125 - 4

0.00000125

Now divide by 0.00001

0.12499998

which is close to 0.125.

Answer:

P(6,-π/6) = (6, -π/6 + 2nπ) and P(-6,-π/6) = (-6, -π/6 + (2n+1)π)

Step-by-step explanation:

We need to find all polar coordinates of

[tex]P = (6,\frac{-\pi }{6})[/tex]

The polar coordinates of any point can be reresented by (r,Ф)

where

(r,Ф) = (r, Ф+2nπ) where n is any integer and r is positive

and

(r,Ф) = (-r, Ф+(2n+1)π) where n is any integer and r is negative.

So, in the question given, r = 6 and Ф = -π/6

So, Polar coordinates will be:

P(6,-π/6) = (6, -π/6 + 2nπ) where where n is any integer and r is positive

and

P(-6,-π/6) = (-6, -π/6 + (2n+1)π) where n is any integer and r is negative.

Answer:

All polar coordinates of point P are [tex](6,-\frac{\pi}{5}+2n\pi)[/tex] and [tex](-6,-\frac{\pi}{5}+(2n+1)\pi)[/tex], where n is an integer.

Step-by-step explanation:

The given point is

[tex]P=(6,-\frac{\pi}{5})[/tex]

If a point is [tex]P=(r,\theta)[/tex], then all polar coordinates of point P are defined as

[tex](r,\theta)=(r,\theta+2n\pi)[/tex]

[tex](r,\theta)=(-r,\theta-(2n+1)\pi)[/tex]

where n is an integer.

In the given point [tex]r=6[/tex] and [tex]\theta=-\frac{\pi}{5}[/tex]. So all polar coordinates of point P are defined as

[tex](6,-\frac{\pi}{5})=(6,-\frac{\pi}{5}+2n\pi)[/tex]

[tex](6,-\frac{\pi}{5})=(-6,-\frac{\pi}{5}+(2n+1)\pi)[/tex]

Therefore all polar coordinates of point P are [tex](6,-\frac{\pi}{5}+2n\pi)[/tex] and [tex](-6,-\frac{\pi}{5}+(2n+1)\pi)[/tex], where n is an integer.

Giselle worked as a carpenter for hours and as a blacksmith for hours, last week will be 18 hours and 12 hours, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Giselle works as a carpenter and as a blacksmith. She earns $20 per hour as a carpenter and $25 per hour as a blacksmith. Last week, Giselle worked both jobs for a total of 30 hours and earned a total of $690.

Let 'x' be the number of hours of a blacksmith and 'y' be the number of hours of a carpenter. Then the equations are given as,

x + y = 30                         ...1

20x + 25y = 690             ...2

From equations 1 and 2, then we have

20(30 - y) + 25y = 690

600 - 20y + 25y = 690

5y = 90

y = 18

Then the value of 'x' is given as,

x + 18 = 30

x = 30 - 18

x = 12

Factors of -3 that add up to +2 are +3 and -1.

Divide by a: +3/3, -1/3

Reduce: +1/1, -1/3

So the factors are x + 1 and 3x - 1.

The coordinates of point s are (-3 , 3)

Step-by-step explanation:

* Lets revise some transformation

- If the point (x , y) translated horizontally to the right by h units

 then the new point  = (x + h , y)

- If the point (x , y) translated horizontally to the left by h units

 then the new point  = (x - h , y)

- If the point (x , y) translated vertically up by k units

 then the new point  = (x  , y + k)

- If the point (x , y) translated vertically down by k units

 then the new point  = (x  , y - k)

* Now lets solve the problem

∵ The vertices of triangle cde are c (-3 , 1) , d (-1 , 4) , e (-6 , 4)

∵ The new coordinates of two vertices are q (-1 , 6) , r (-6 , 6)

- The image of point d is q and the image of point e is r

∵ Point d = (-1 , 4) and point q = (-1 , 6)

∵ Point e = (-6 , 4) and point r = (-6 , 6)

- The x-coordinate has no change but the y-coordinate added by 2

∴ The triangle cde translated vertically up by 2 units to create the

  congruent triangle sqr

- Lets translate point c two units up to find the coordinates of point s

∵ Point c = (-3 , 1)

∴ Poin s = (-3 , 1 + 2) = -3 , 3)

* The coordinates of point s are (-3 , 3)

Answer:

10.125 feet

Step-by-step explanation:

h(t) = -2t² + 3t + 9

The maximum height is at the vertex of the parabola.  For a parabola ax² + bx + c, the vertex is at x = -b/(2a).

t = -3 / (2×-2)

t = 3/4

h(3/4) = -2(3/4)² + 3(3/4) + 9

h(3/4) = -9/8 + 9/4 + 9

h(3/4) = 81/8

h(3/4) = 10.125 feet

The magnitude of the net force on the box is 100 Newtons to the left.

A force is the result of the interaction between two things and can be either a push or a pull. Due to the fact that it is a vector quantity, it possesses both magnitude and direction. The object's state of motion, direction, size, and form might all change as a result.

Given, the box is being pushed to the right with a force of 300 newtons, and to the left with a force of 400 newtons.

Here,

400 newtons > 300 newtons

400 newtons is much more than 300 newtons,

The net force on the box will be the sum of F₁ and F₂.

Answer:

y = x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (5, 4) and (x₂, y₂ ) = (- 4, - 5)

m = [tex]\frac{-5-4}{-4-5}[/tex] = [tex]\frac{-9}{-9}[/tex] = 1, thus

y = x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (5, 4), then

4 = 5 + c ⇒ c = 4 - 5 = - 1

y = x - 1 ← equation in slope- intercept form

The final equation is y = x - 1.

To find the equation of the line in slope-intercept form, which is y = mx + b, we need two pieces of information: the slope (m) and the y-intercept (b). First, let's calculate the slope using the two given points (5,4) and (-4,-5).

The formula for slope is:

m = (y2 - y1) / (x2 - x1)

Therefore:

m = (-5 - 4) / (-4 - 5) = (-9) / (-9) = 1

Now that we have the slope, we use one of the points to solve for the y-intercept. By substituting the slope and the coordinates of one of the points into the equation, we get:

4 = (1)(5) + b

4 = 5 + b

b = 4 - 5 = -1

Finally, the equation of the line in slope-intercept form is:

y = x - 1

You multiply 27.50 with 5 and then divise by 100 (5%).It is around $1.37 to &1.38

To calculate the sales tax on a $27.50 purchase at 5%, convert 5% to decimal form (0.05) and multiply by the purchase amount. This results in a tax of $1.38, and the total cost with tax is $28.88.

To find the amount of sales tax due on a purchase of $27.50 with a 5% tax rate, you should first convert the percentage to a decimal. To do this, you divide by 100 or simply move the decimal point two places to the left. Thus, 5% becomes 0.05 as a decimal. Then, multiply this decimal by the total cost of the purchase to calculate the sales tax.

This calculation is as follows: $27.50 \ imes 0.05 = $1.375.

Since you generally do not pay fractions of a cent, you would round this number to the nearest cent, making the sales tax $1.38. The total cost with tax would then be the sum of the original cost plus the sales tax: $27.50 + $1.38 = $28.88.

You can calculate the surface area of this right prism by adding the area of its faces.

You can observe that the faces of the right prism are:  Three different rectangles and two equal triangles.

The formula for calculate the  area of a rectangle is:

[tex]A=lw[/tex]

 Where "l" is the lenght and "w" is the width.

The formula for calculate the  area of a triangle is:

[tex]A=\frac{bh}{2}[/tex]

Where "b" is the base and "h" is the height.

You can observe that the hypotenuse of the each triangle is the width of one of the larger rectangle, then , you can find its value with the Pythagorean Theorem:

[tex]a=\sqrt{b^2+c^2}[/tex]

Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.

Then, this is:

[tex]a=\sqrt{(8units)^2+(15units)^2}=17units[/tex]

Therefore, you can add the areas of the faces to find the surface area of the right prism (Since the triangles are equal, you can multiply the area of one of them by 2). This is:

[tex]SA=(10units)(8units)+(15units)(10units)+(17units)(10units)+2(\frac{(15units)(8units)}{2})\\\\SA=520units^2[/tex]
