Answer:

\Huge \boxed{\mathrm{1.38 \ ft}}

\rule[225]{225}{2}

Step-by-step explanation:

\sf 1 \ cm = \displaystyle \frac{1}{30.48} \ ft

To convert 42 cm to ft:

\Longrightarrow \sf \displaystyle \ \ 42 \times \frac{1}{30.48}

\Longrightarrow \sf \displaystyle \ \ \frac{42}{30.48}

\Longrightarrow \sf \displaystyle \ \  1.37795...

42 cm is approximately 1.38 ft.

\rule[225]{225}{2}

Step-by-step explanation:

There is infinitely many ratios which are equivalent to 5:9. As we know always we can write divide as fraction, so . We can multiply nominator and denominator by the any number (but the same) and get another numbers but ratio will be the same, so equivalent.

For example

10:18,

15:27

Hope this helps.

Select the correct answer​
Paladinen [302]

Answer:

a)  We get \mathbf{A+B=x^2-2x+1}

So, Is the result of A+B is a polynomial:Yes

b) We get \mathbf{A-B=6x^3-7x^2+2x-1}

So, Is the result of A-B is a polynomial:Yes

c)  We get \mathbf{A.B=9x^6+21x^5-18x^4+9x^3-3x^2}

So, Is the result of A.B is a polynomial:Yes

Step-by-step explanation:

We are giving the polynomial equations:

A= 3x^2(x-1)\\B=-3x^3+4x^2-2x+1

We need to find

a) A+B

A+B=3x^2(x-1)+(-3x^3+4x^2-2x+1)\\A+B=3x^3-3x^2-3x^3+4x^2-2x+1\\A+B=3x^3-3x^3-3x^2+4x^2-2x+1\\A+B=x^2-2x+1\\

So, we get \mathbf{A+B=x^2-2x+1}

So, Is the result of A+B is a polynomial:Yes

b) A-B

A-B=3x^2(x-1)-(-3x^3+4x^2-2x+1)\\A-B=3x^3-3x^2+3x^3-4x^2+2x-1\\A-B=3x^3+3x^3-3x^2-4x^2+2x-1\\A-B=6x^3-7x^2+2x-1\\

So, we get \mathbf{A-B=6x^3-7x^2+2x-1}

So, Is the result of A-B is a polynomial:Yes

c) A . B

A.B=3x^3(-3x^3+4x^2-2x+1)-3x^2(-3x^3+4x^2-2x+1)\\A.B=9x^6+12x^5-6x^4+3x^3+9x^5-12x^4+6x^3-3x^2\\A.B=9x^6+12x^5+9x^5-6x^4-12x^4+3x^3+6x^3-3x^2\\A.B=9x^6+21x^5-18x^4+9x^3-3x^2

So, we get \mathbf{A.B=9x^6+21x^5-18x^4+9x^3-3x^2}

So, Is the result of A.B is a polynomial:Yes

Step-by-step explanation:

DCB and ABC are right angles

DCB = 90 = 7x + 34

If 7x + 34 = 90, then 7x = 56 and x = 8

Find a polynomial P(x) with the zeros x=2, −(2), √3, −√3
Zigmanuir [339]

Answer:

P(x) = x^{4} - 7x² + 12

Step-by-step explanation:

Given zeros x = 2, x = - 2, x = \sqrt{3}, x = - \sqrt{3}

Then the factors are (x - 2), (x + 2), (x - \sqrt{3} ), (x + \sqrt{3} )

and the polynomial is the product of the factors, that is

P(x) = (x - 2)(x + 2)(x - \sqrt{3} )(x + \sqrt{3} ) ← expand in pairs using FOIL

      = (x² - 4)(x² - 3) ← distribute

     = x^{4} - 3x² - 4x² + 12 ← collect like terms

    = x^{4} - 7x² + 12

The diameter is 12 inches. What is the area? What do I do to solve it please help!
SashulF [63]

Answer:

113.04 sq. in.

Step-by-step explanation:

If the diameter of the circle is 12", then the radius is 6" (half the diameter), and the area "A" is (approximately) 3.14 * 6^2. The calculation is approximate because 3.14 is a rounded value for pi.
