Verify rolles theorem for the function f(x)=2x*3+x*2-4x-2

Answer»

Answer:

Step-by-step explanation:

The GIVEN function f(x) = 2x^{3} + x^{2} - 4x - 2 ...(i)       ( when \frac{-1}{2}≤x≤\sqrt{2} )

∴f(\frac{-1}{2})=2(\frac{-1}{8})+\frac{1}{<klux>4</klux>}-4(\frac{-1}{2})-2 = -1/4 +1/4+2-2 =0

∴f(\sqrt{2}) = 2.((\sqrt{2}) ^{3})+(\sqrt{2}) ^{2}-4.\sqrt{2}-2 = 4.\sqrt{2}+2-4.\sqrt{2}-2=0

f(\frac{-1}{2})=f(\sqrt{2})

Diff. (i) w.r. to 'x' both sides, we get

f'(x) = 6x^{2} + 2X - 4 replace with 'C' then

∴ f'(c) = 6c^{2} + 2c - 4

By Rolle's Theorems,

∴ 6c^{2} + 2c - 4 =0

6c^{2} + 6c - 4c - 4 = 0

6c(c + 1) - 4(c + 1) = 0

(c + 1)(6c - 4) = 0

∴c≠-1 ,c=  \frac{4}{6}=\frac{2}{3}

∴c ∈[\frac{-1}{2},\sqrt{2}]

Hence, verified Rolle's theorem.

The mass of a single barium atom is 2.28×10-22 grams. How many barium atoms would there be in 306 milligrams of barium?

Answer»

Given:

MASS of single barium atom = 2.28×10⁻²² grams

Mass of barium = 306 MILLIGRAMS = 0.396 grams

To FIND:

Number of ATOMS in 306 milligrams of barium

Calculation:

We know the formula

Number of atoms = Total mass / Mass of single atom

                             = 0.306 / 2.28×10⁻²²

                             = 0.134×10²²

                             = 13.4×10²⁰ atoms

Number of atoms in 306 milligrams of barium is 13.4×10²⁰ atoms

Find the simplest rationalising of √5-√2​

Answer»

Answer:

Rationalising Factor is (√5-√3)

Answer is 2

Step-by-step EXPLANATION:

Given,

√5-√2

For Rationalising let us MULTIPLY by

√5+√3

So,

(√5-√3)(√5-√3)

(a+b)(a-b)=a^2 - b^2

So,

(√5-√3)(√5-√3) = (√5)^2 - (√3)^2

Here SQUARE and ROOT gets cancelled

Remaining,

5-3

=2,

Obtain all othere zeroes of the polynomialif two of its zeroes are and​

Answer»

EXPLANATION.

Two ZEROES are = √2 and -√2

zeroes of polynomial.

=> x = √2 and x = -√2

=> x - √2 and x + √2

PRODUCTS of zeroes of polynomial.

=> ( x - √2 ) ( x + √2 )

=> x² - 2

divide 3x³ - 4x - x² + 2 by x² - 2

we GET,

=> 2x - 1

Now,

zeroes of the equation

=> 2x - 1 = 0

=> x = 1/2

Therefore,

All zeroes are = 1/2 , √2 , -√2
