Why do centre of mass describes only translatory motion

Answer»

The CoM will always remain at the same position with respect to the body(unless the body CHANGES it's shape). HOWEVER, suppose a ball(with CoM at its geometrical centre) is moving ALONG X-axis at 1 m/s. Then the position of CoM will keep increasing by 1m every second from the origin, but ACTUALLY it will still always lie at the geometrical centre of the ball.

(5x⁴ - 3x³ + 4x² + 2x - 6) ÷ x². What is the quotient and remainder?

Answer»

Answer:

Step-by-step explanation:

GIVEN (5x⁴ - 3x³ + 4x² + 2X - 6) ÷ x². What is the quotient and remainder?

So we need to divide a polynomial (more than one term) by a MONOMIAL which has one term.  

So let us divide.

    x^2) 5x⁴ - 3x³ + 4x² + 2x - 6 (5 x^2 - 3 x + 4

            5x⁴ - 3x³ + 4x²

        ------------------------------- By SUBTRACTING we get

                           2 x - 6

After dividing, the quotient will be 5 x^2 - 3 x + 4 and remainder is 2 x - 6

The product of 2 rational numbers is 24.If one of them is -36/11.find the other

Answer»

LET the 2 no.s be x and y
So PRODUCT will be xy
xy=24
It is GIVEN that one of the no. Is -36/11
So x × -36/11= 24
X= 24÷-36/11
x= 24×11/36
x= 22/-3
ie; -22/3
Now check the answer by substituting it

(15y⁴ + 10y³ - 3y²) ÷ 5y². What is the quotient and remainder?

Answer»

Answer:

Quotient 3y² + 2y  - 1

REMAINDER = 2

Step-by-step EXPLANATION:

(15y⁴ + 10y³ - 3y²) ÷ 5y². What is the quotient and remainder?

Numerator = 15y⁴ + 10y³ - 3y²

= y²  (15y² + 10y - 3)

Denominator = 5y²

Cancelling y² from numerator & denominator

(15y² + 10y - 3)/5

= (15y² + 10y - 5 + 2)/5

= (5(3y² + 2y  - 1) + 2)/5

=5(3y² + 2y  - 1)/5  + 2/5

Quotient 3y² + 2y  - 1

Remainder = 2

30.

Divide the polynomial 6x³ + 8x² by the monomial 2x. What is the quotient and remainder?

Answer»

Answer:

3 x^2 + 4 x

Step-by-step explanation:

Given Divide the polynomial 6x³ + 8x² by the monomial 2x. What is the QUOTIENT and remainder?

So we need to divide a polynomial (more than one TERM) by a monomial which has one term.

So LET us divide.

        2 x ) 6 x^3 + 8 x^2 ( 3 x^2 + 4 x

                 6 x^3                             by subtracting

             --------------------------------

                         - 8 x^2

                           8 x^2

            ---------------------------------

                              0

So now quotient is zero and remainder is 3 x^2 + 4 x

What should be added twice the rational number -7/3 to get 3/7

Answer»

Heya !!



2 × -7/3 = -14/3



Let X should be added to -14/3 to GET 3/7.




Therefore,




-14/3 + X = 3/7




X = ( 3/7 + 14/3 )






X = ( 9 + 98)/21




X = 107/21



Hence,


107/21 should be added to-14/3 to get 3/7.

One zero of the polynomialis 2 / 3 . Find the other zeroes

Answer» \bold{Answer :}

SINCE, 2/3 is a ZERO of the given polynomial, (3x - 2) is a factor of it.

Now,

3x³ + 16x² + 15x - 18

= 3x³ - 2x² + 18x² - 12X + 27x - 18

= x² (3x - 2) + 6x (3x - 2) + 9 (3x - 2)

= (3x - 2) (x² + 6x + 9)

= (3x - 2) (x + 3)²

= (3x - 2) (x + 3) (x + 3)

So, all the FACTORS of the given polynomial are (3x - 2), (x + 3) and (x + 3)

Therefore, all its ZEROES are 2/3, (- 3) and (- 3).

If 4 x square + 9 y square equal to 69 and xy equal to 1 find the value of 2 X + 3 y

Answer»

(2X + 3y)^2
= 4x^2 + 9y^2 + 2×2x × 3y
= 4x^2 + 9y^2 + 12XY
= 69 + 12×1
= 81
hence
(2x + 3y)^2 = 81
so
2x+3y = √81
2x + 3y = 9
