good morning....

have a GREAT day....

Answer:

Step by step solution :

Step 1:

Polynomial Roots Calculator :

1.1 Find roots (zeroes) of : F(x) = x4-x-10

Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0

Rational Roots TEST is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers

The Rational ROOT Theorem states that if a polynomial zeroes for a rational number P/Q then P is a FACTOR of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 1 and the Trailing Constant is -10.

The factor(s) are:

of the Leading Coefficient : 1

of the Trailing Constant : 1 ,2 ,5 ,10

Step 2 :

Quadratic equations:

2.1 Solve x4-x-10 = 0

In search of an interavl at which the above polynomial CHANGES sign, from negative to positive or the other wayaround.

Method of search: Calculate polynomial values for all integer points between x=-20 and x=+20

Found change of sign between x= -2.00 and x= -1.00

Approximating a root using the Bisection Method :

We now use the Bisection Method to approximate one of the solutions. The Bisection Method is an iterative procedure to approximate a root (Root is another name for a solution of an equation).

The FUNCTION is F(x) = x4 - x - 10

At x= -1.00 F(x) is equal to -8.00

At x= -2.00 F(x) is equal to 8.00

Intuitively we feel, and justly so, that since F(x) is negative on one side of the interval, and positive on the other side then, somewhere inside this interval, F(x) is zero.

x = -1.697471857

>>Given a set of n + 1 DATA POINTS (xi, yi) where no TWO xi are the same, one is looking for a polynomial p of degree at most n with the property. The unisolvence theorem states that such a polynomial p exists and is UNIQUE, and can be proved by the Vandermonde matrix, as DESCRIBED below.

x3 − x2 – 4x + 4 = 0

There is an extremely complicated formula for solving cubic equations. Some calculators have this formula built in and therefore can be used to solve cubic equations.

We are going to learn how these equations can be solved by factorising. If the equation has solutions that are integers  a, b and C then we can factorise the equation as follows:

   x3 − x2 – 4x + 4 = (x − a)(x − b)(x − c) = 0

Multiplying the brackets together we see that the constant term, 4, must be the NUMBER we GET when we multiply a, b and c together.

   abc = 4

All the solutions a, b and c must be factors of 4 so there are not many whole numbers that we need to consider.

We have only the FOLLOWING possibilities:

   ±1, ±2 and ±4

We’ll examine each of these numbers to find which ones are solutions of the equation.

   f(1) = 13 − 12 – 4×1 + 4 = 0                        1 is a solution

   f(−1) = (−1)3 − (−1)2 – 4×(−1) + 4 = 6    

   f(2) = 23 − 22 – 4×2 + 4 = 0                         2 is a solution

  f(−2) = (−2)3 − (−2)2 – 4×(−2) + 4 = 0        −2 is a solution

We have now found three solutions so we don’t need to try  4 and −4 as a cubic equation has a maximum of three solutions.

These three numbers give us the values of a, b and c and we can  factorise the equation.

   x3 − x2 – 4x + 4 = (x − 1)(x − 2)(x + 2) = 0

This method involves finding integers that are factors of ( can be divided into ) the constant term and then testing whether these integers are solutions of the equation.

Unfortunately we cannot ASSUME that the solutions of a third degree equation are all integers.

However, if we can find one integer solution, lets say it is x = a then, by the remainder theorem , we know that (x − a) is a factor of the equation. We can find another factor, a quadratic factor,  by division.

Answer:

8/3

Step-by-step explanation:

In an AP,

First term (a) = 5

Last term (L) = 45

Sum of the TERMS of the AP (Sn) = 400

Number of terms = (N) = ?

Common difference = (d) = ?

Now,

Sn = n/2 × (a + l)

=> 400 = n/2 × (5 + 45)

=> n/2 × 50 = 400

=> n = (400 × 2)/50

=> n = 16

Again,

l = a + (n - 1)d

=> 45 = 5 + (16 - 1) × d

=> 45 - 5 = 15d

=> d = 40/15 = 8/3

PRODUCT of √15 and √60 is 30

Product of √2 and 2√2 is 4

There are INFINITE pairs.

ANSWER:

80 PERCENT of 16 RUPEE is 12.80rupees

Step-by-step EXPLANATION:

Let the UNKNOWN number be X.

given that, when x is multiplied to itself the PRODUCT is 251953.8095.

thus,

=> x = 501.9500069728

=> x = 5019500069728/ 10000000000

hence, the required no. is 5019500069728/ 10000000000.

Answer:

SORRY i can't understand UR QUESTIONS.

Answer:

116 or 56

Step-by-step explanation:

x-y =2

or

x= y+2

substitute this in XY = 15

(y+2)y =15

y^2 + 2Y = 15

y^2 + 2y - 15 = 0

solving quadratic eqn

y^2 - 3Y + 5y -15 = 0

y = -5 y = 3

x - y = 2

when y = 3 ,x = 5

when y= 2, x = 4

so x^3 - y^3 = 5^3 - 3^3 = 125 - 9 = 116

or

4^3 - 2^3 = 64 - 8 = 56

so ans is 116 or 56

ANSWER:

Actually nothing of this NUMBERS are DIVISIBLE by the given disvisibilities

Hey there!!

To SOLVE this question, we will be using the zero theorem.

We know that ( x -2 ) is a factor of x² + ax - 6. This means, it leaves a REMAINDER of 0 and when x - 9x + b is divided by ( x - 2 ), it leaves a remainder of 0 too.

We will know take x - 2 = 0 and take x as 2.

Now, all we have to do is SUBSTITUTE the value of 'x' in both equations and find the value of a and b.

First, let's find for a :

x² + ax - 6 ; we know that x is 2

... (2)² + a(2) - 6 = 0

... 4 + 2a - 6 = 0

... -2 + 2a = 0

... 2a = 2

... a = 1

Now, let's solve for b:

x² - 9x + b ; We know that x is 2.

... (2)² - 9(2) + b = 0

... 4 - 18 + b = 0

... -14 + b = 0

... b = 14

We now know the values of a and b. a = 1 , b = 14
