2.

For what values of b is the polynomial x cube - 3 x + b x - 6 divisible by x - 3

Answer»

<P>p(X) = -3x+bx-6

g(X)= x-3

x-3=0

x=3

Substituting value of x in p(X)

-3(3)+B(3)-6=0

-27+3b-6=0

4.	What are the all degree of polynomial
Answer» hola mate...!!! The degree of a POLYNOMIAL is the highest of the DEGREES of its monomials (individual terms) with non-zero coefficients. The degree of a term is the sum of the exponents of the variables that appear in it, and thus is a non-negative integer. The term order has been used as a synonym of degree but, nowadays, may refer to several other concepts (see order of a polynomial (disambiguation). The following names are assigned to polynomials according to their degree: SPECIAL case – zero Degree 0 – non-zero constant Degree 1 – linear Degree 2 – quadratic Degree 3 – cubic Degree 4 – quartic (or, if all terms have even degree, biquadratic) Degree 5 – quintic Degree 6 – sextic (or, less commonly, hexic) Degree 7 – septic (or, less commonly, heptic) For higher degrees, names have sometimes been proposed,but they are RARELY used: Degree 8 – octic Degree 9 – nonic Degree 10 – decic

5.	the denominator of a fraction is one more than its numerator if one is deducted from both the numerator and the denominator the fraction becomes equivalent 0.5 the fraction is
Answer» *GIVEN: The* *denominator* of a FRACTION is ONE more than its numerator let the numerator be x and the denominator be x+ 1 so the fraction is => x/x+1 If one is deducted from both numerator and DENOMINATOR the fraction will be equal to 0.5 => x-1/x+1-1 = 0.5 => x-1/x = 5/10 => x-1/x = 1/2 By cross multiplying => x = 2(x-1) => x = 2x-2 => x-2x = -2 => -x = -2 => x = 2 so x+1 = 2+1 = 3 so the original fraction is 2 hope it helps you**

5.

the denominator of a fraction is one more than its numerator if one is deducted from both the numerator and the denominator the fraction becomes equivalent 0.5 the fraction is

Answer»

GIVEN:

The denominator of a FRACTION is ONE more than its numerator

let the numerator be x and the denominator be x+ 1

so the fraction is => x/x+1

If one is deducted from both numerator and DENOMINATOR the fraction will be equal to 0.5

=> x-1/x+1-1 = 0.5

=> x-1/x = 5/10

=> x-1/x = 1/2

By cross multiplying

=> x = 2(x-1)

=> x = 2x-2

=> x-2x = -2

=> -x = -2

=> x = 2

so x+1 = 2+1 = 3

so the original fraction is 2

hope it helps you

If x= 3+2√2,then find the value of x+1\x

Answer»

Given:

x=3+2√2

To find the value of,

$\sf{x + \frac{1}{x} } \\ \\$

Here,

We find the value of 1/x and then,add it with that of x. THUS, deriving the required value.

Now,

What is rationalising?

Rationalising is a mathematical TOOL or procedure which is applied to REMOVE the RADICAL signs EITHER by multiplying or dividing.

So,

$\sf{ \frac{1}{x} = \frac{1}{3 + 2 \sqrt{2} } } \\ \\ \: \: \: \: \: = \sf{ \frac{1}{3 + 2 \sqrt{2} } \times \frac{3 - 2 \sqrt{2} }{3 - 2 \sqrt{2} } } \\ \\ \: \: \: \: = \sf{\frac{3 - 2 \sqrt{2} }{3 {}^{2} - 2 \sqrt{2 {}^{2} } }} \ \\ \\ \: \: \: = \sf{\frac{3 - 2 \sqrt{2} }{9 - 8}} \\ \\ \implies \: \sf{ \frac{1}{x} = 3 - 2 \sqrt{2} }$

On adding both the term,

(3+2√2)+(3-2√2)

=3+3

=6

$\sf{6 \: is \: the \: value \: of \: x + \frac{1}{x} } \\ \\$

Prove that,in an isosceles triangle,the bisector of the vertical angle,the altitude from the vertex and the median to the base are coincident.

Answer»

Answer:

Proof:

Consider the two triangles ABD and ACD,

AB = AC (Given)

Angle BAD = Angle CAD (since given AD bisects angle BAC)

AD = AD (Common sides)

Thus the two triangles ABD and ACD are consistent (By 'SAS' compatibility adage of triangles)

therefore angle ADB = edge ADC - (1) (Corresponding parts of

CONGRUENCE triangles are equivalent)

In any case, these two are direct PAIR that is their entirety is 180 degrees - (2)

Thus from (1) and (2), EVERY one of the points ADB and ADC are 90 degrees.

Therefore, AD is perpendicular to BC.

Answer» Answer: $\large{\red{\boxed{\sf \frac{7 + 3 \sqrt{5} }{3 + \sqrt{5}} - \frac{7 - 3 \sqrt{5} }{3 - \sqrt{5} } = \sqrt{5}}}}$ Step-by-step explanation: GIVEN that ; $\dfrac{7 + 3 \sqrt{5} }{3 + \sqrt{5} } - \dfrac{7 - 3 \sqrt{5} }{3 - \sqrt{5} }$ LET a = $\sf \dfrac{7 + 3\sqrt{5}}{3 + \sqrt{5}}$ and, B = $\sf \dfrac{7 - 3\sqrt{5}}{3 - \sqrt{5}}$ We need to FIND, (a - b) - CONSIDER a; $\frac{7 + 3 \sqrt{5} }{3 + \sqrt{5} } \\ \\ \implies \frac{7 + 3 \sqrt{5} }{3 + \sqrt{5} } \times \frac{3 - \sqrt{5} }{3 - \sqrt{5} } \\ \\ \implies \frac{(7 + 3 \sqrt{5} )(3 - \sqrt{5} )}{(3) {}^{2} - ( \sqrt{5}) {}^{2} } \\ \\ \implies \frac{35 + 9 \sqrt{5} - 7 \sqrt{5} - 15 }{9 - 5} \\ \\ \implies \frac{20 + 2 \sqrt{5} }{4} \\ \\ \implies \frac{2(10 + \sqrt{5}) }{4}\\ \\ \implies \frac{10 + \sqrt{5} }{2}$ Consider b; $\frac{7 - 3 \sqrt{5} }{3 - \sqrt{5} } \\ \\ \implies \frac{7 - 3 \sqrt{5} }{3 - \sqrt{5} } \times \frac{3 + \sqrt{5} }{3 + \sqrt{5} } \\ \\ \implies \frac{(7 - 3 \sqrt{5})(3 + \sqrt{5})}{(3) {}^{2} - ( \sqrt{5}) {}^{2} } \\ \\ \implies \frac{35 + 7 \sqrt{5} - 9 \sqrt{5} - 15}{9 - 5} \\ \\ \implies \frac{20 - 2 \sqrt{5} }{4} \\ \\ \implies \frac{2(10 - \sqrt{5}) }{4} \\ \\ \implies \frac{10 - \sqrt{5} }{2}$ Now, find (a - b) - $\implies \frac{10 + \sqrt{5} }{2} - \frac{10 - \sqrt{5} }{2} \\ \\ \implies \frac{10 + \sqrt{5} - (10 - \sqrt{5}) }{2} \\ \\ \implies \frac{10 + \sqrt{5} - 10 + \sqrt{5} }{2} \\ \\ \implies \frac{2 \sqrt{5}}{ 2} \\ \\ \boxed{ \bf \therefore \: \frac{7 + 3 \sqrt{5} }{3 + \sqrt{5}} - \frac{7 - 3 \sqrt{5} }{3 - \sqrt{5} } = \sqrt{5} }$

Answer»

Answer:

$\large{\red{\boxed{\sf \frac{7 + 3 \sqrt{5} }{3 + \sqrt{5}} - \frac{7 - 3 \sqrt{5} }{3 - \sqrt{5} } = \sqrt{5}}}}$

Step-by-step explanation:

GIVEN that ;

$\dfrac{7 + 3 \sqrt{5} }{3 + \sqrt{5} } - \dfrac{7 - 3 \sqrt{5} }{3 - \sqrt{5} }$

LET a = $\sf \dfrac{7 + 3\sqrt{5}}{3 + \sqrt{5}}$ and,

B = $\sf \dfrac{7 - 3\sqrt{5}}{3 - \sqrt{5}}$

We need to FIND, (a - b) -

CONSIDER a;

$\frac{7 + 3 \sqrt{5} }{3 + \sqrt{5} } \\ \\ \implies \frac{7 + 3 \sqrt{5} }{3 + \sqrt{5} } \times \frac{3 - \sqrt{5} }{3 - \sqrt{5} } \\ \\ \implies \frac{(7 + 3 \sqrt{5} )(3 - \sqrt{5} )}{(3) {}^{2} - ( \sqrt{5}) {}^{2} } \\ \\ \implies \frac{35 + 9 \sqrt{5} - 7 \sqrt{5} - 15 }{9 - 5} \\ \\ \implies \frac{20 + 2 \sqrt{5} }{4} \\ \\ \implies \frac{2(10 + \sqrt{5}) }{4}\\ \\ \implies \frac{10 + \sqrt{5} }{2}$

Consider b;

$\frac{7 - 3 \sqrt{5} }{3 - \sqrt{5} } \\ \\ \implies \frac{7 - 3 \sqrt{5} }{3 - \sqrt{5} } \times \frac{3 + \sqrt{5} }{3 + \sqrt{5} } \\ \\ \implies \frac{(7 - 3 \sqrt{5})(3 + \sqrt{5})}{(3) {}^{2} - ( \sqrt{5}) {}^{2} } \\ \\ \implies \frac{35 + 7 \sqrt{5} - 9 \sqrt{5} - 15}{9 - 5} \\ \\ \implies \frac{20 - 2 \sqrt{5} }{4} \\ \\ \implies \frac{2(10 - \sqrt{5}) }{4} \\ \\ \implies \frac{10 - \sqrt{5} }{2}$

Now, find (a - b) -

$\implies \frac{10 + \sqrt{5} }{2} - \frac{10 - \sqrt{5} }{2} \\ \\ \implies \frac{10 + \sqrt{5} - (10 - \sqrt{5}) }{2} \\ \\ \implies \frac{10 + \sqrt{5} - 10 + \sqrt{5} }{2} \\ \\ \implies \frac{2 \sqrt{5}}{ 2} \\ \\ \boxed{ \bf \therefore \: \frac{7 + 3 \sqrt{5} }{3 + \sqrt{5}} - \frac{7 - 3 \sqrt{5} }{3 - \sqrt{5} } = \sqrt{5} }$
