In most cases, a private company is owned by the company's founders, management, or a group of private investors. A public company is a company that has sold all or a portion of itself to the public via an initial public offering.

3 times the sum of x and y squared plus 5 times the difference of 2x and y

Virty [35]

3x + xy^2 + 5x - 2xy ok so once you can decode the sentence this is what it will look like. First you add the common facts which are 3x and 5x which = 8x ok so now we have 8x + xy^2 - 2xy so then I believe you cant do anything after that because there will be no more common factors hey can you tell me if I am write if you have already had turn this in please hope this helps

The rectangular bar is connected to the support bracket with a 10-mm-diameter pin. The bar width is w = 70 mm and the bar thickn

german

Answer:

P_max = 9.032 KN

Step-by-step explanation:

Given:

- Bar width and each side of bracket w = 70 mm

- Bar thickness and each side of bracket t = 20 mm

- Pin diameter d = 10 mm

- Average allowable bearing stress of (Bar and Bracket) T = 120 MPa

- Average allowable shear stress of pin S = 115 MPa

Find:

The maximum force P that the structure can support.

Solution:

- Bearing Stress in bar:

T = P / A

P = T*A

P = (120) * (0.07*0.02)

P = 168 KN

- Shear stress in pin:

S = P / A

P = S*A

P = (115)*pi*(0.01)^2 / 4

P = 9.032 KN

- Bearing Stress in each bracket:

T = P / 2*A

P = T*A*2

P = 2*(120) * (0.07*0.02)

P = 336 KN

- The maximum force P that this structure can support:

P_max = min (168 , 9.032 , 336)

P_max = 9.032 KN

I'm genuinely lost in any problems like this and my teachers are no help, I need help doing exponents in general, everything to

Stolb23 [73]

Answer:

See below.

Step-by-step explanation:

So we have the expression:

$(-6n^{-3})^2$

We can use the power of a product property, where:

$(ab)^n=a^n\cdot b^n$

So:

$=(-6)^2\cdot(n^{-3})^2$

For the left, -6 squared is the same as -6 times -6. This equals positive 36.

For the right, we can use the power of a power property. The property says that:

$(a^n)^k=a^{nk}$

So:

$(n^{-3})^2=n^{(-3)(2)}\\=n^{-6}$

So, all together, we have:

$=(-6)^2\cdot(n^{-3})^2\\=36n^{-6}$

We have the expression:

$-\frac{3x^0}{x^4}$

First, note that anything to the zeroth power (except for 0) is 1, thus, x^0 is also 1. Simplify:

$=-\frac{3}{x^4}$

And that's the simplest we can do :)

Notes for 6)

We <em>can</em> put the x^4 to the numerator. Recall that when you put an exponent to opposite side, you put a negative. In other words:

$x^n=\frac{1}{x^{-n}}$

And vice versa:

$\frac{1}{x^{-n}}=x^n$

So, we can write the above as:

$=-\frac{3}{x^4}\\=-\frac{3}{x^{-(-4)}}\\=-3x^{-4}$

However, traditionally, we want only positive exponents, so this wouldn't be correct.

Write and equation for vertical translation y=2/3x ; 3 units down

OlgaM077 [116]

Answer:

y=2/3x - 3

Step-by-step explanation:

In order to move an equation down, you just subtract how many units you want to move down on the graph. In this case, you want to move 3 units down, so that's why you subtract by 3. Easy as that!

Is y^2+25y+200 a perfect trinomial

lukranit [14]

No because the perfect trinomial has a square as the third term and the middle term is a multiple of 2.
