19.

find the zeroes of the quadratic polynomial 3x2-x-4 and verify the relationship between the zeroes and coefficient.

Answer»

Solution

Given :-

Equation, 3x² - x - 4 = 0

Find :-

Its roots

Explanation

Let,

P & Q be roots of this Equation.

Using Formula

★ Sum of roots = - ( Coefficient of x)/(coefficient of x²)

★ product of roots = (constant part)/(coefficient of x²)

So, keep above Value,

==> sum of roots = -(-1)/3

==> P + Q = 1/3____________(1)

And,

==> Product of roots = -4/3

==> P.Q = -4/3

==> P = -4/(3Q)____________(2)

keep in EQU(1)

==> -4/(3Q) + Q = 1/3

==> (-4 + 3Q² ) × 3 = 3Q

==> 9Q² - 3Q - 12 = 0

==> 3Q² - Q - 4 = 0

==> 3Q² - 4Q + 3Q - 4 = 0

==> Q(3Q - 4) + 1(3Q - 4) = 0

==> (3Q - 4)(Q + 1)= 0

==> 3Q - 4 = 0 Or, Q + 1 = 0

==> Q = 4/3 Or, Q = -1

keep value of Equation (1)

When,

Q = 4/3

==> P + 4/3 = 1/3

==> P = 1/3 - 4/3

==> P = (1- 4)/3

==> P = -3/3

==> P = -1

When,

Q = -1,

==> P - 1 = 1/3

==> P = 1/3 + 1

==> P = (1 + 3)/3

==> P = 4/3

Since

Roots will be of this Equation, 4/3 , -1 Or, -1 , 4/3.

______________________________

Answer Verification

★Sum of roots = 1/3

==> 4/3 - 1 = 1/3

==> ( 4 - 3)/3 = 1/3

==> 1/3 = 1/3

L.H.S. = R.H.S.

That's Proved.

Answer»

Answer:

maybe 13, or maybe 25

Step-by-step explanation:

There are 2 solutions for this.

Solution 1

Multiplying the TWO digit integers and then adding the digits of its product GIVES us the answer.

Multiply 12*12=144

Sum of the digits of its product 1+4+4=9

Therefore 12*12=9

In the same way

Multiply 23*23=529

Sum of the digits of its product 5+2+9=16

And now

Multiply 34*34=1156

Sum of the digits of its product 1+1+5+6=13

Therefore 34*34=13

Solution 2

The square of the third number to the digit in the integer gives us the answer.

12*12 ,third number is 3, HENCE 3 power 2 is 9

23*23, third number is 4, hence 4 power 2 is 16

Similarly,

34*34, third number would be 5, hence 5 power 2 is 25

Therefore 34*34=25.

Solution:-

━━━━━━━━━━━━━━━━━━━━━━━━━━

$\large\to{\underbrace{\underline{\sf{Understanding\:the\:concept:-}}}}$

$\implies$ Here a percentage have been given to us that is 10.5%. Now the question has ASKED us to express the following percentage as ratios in the reduced form.

⛤ HOW TO DO:-

$\to$ Here to convert the given percentage into ratios first of all we need to remove the decimal POINT. When we will remove the decimal point we will have to 10 in the denominator. As percentage is calculated out of 100 we will divide it by 100. Then by simplifing it further we will get the answer. SEE the solution below for answer.

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

ANSWER:-

⇉ 10.5% will be expressed as 21/200 in ratios.

GIVEN:-

» Percentage = 10.5%

TO FIND:-

Here we have to express the given percentage as ratios in the reduced form.

SOLUTION:-

Follow the steps below

We know that:-

We have to remove the decimal point.
As we remove the point there was a number after it so we will write 10 in 0.
Dividing by 100.
By simplifing it further we will get the answer.

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

So let's solve it!

Expressing the percentage as ratios:-

Removing the decimal point = 105/10

So,

➪ 105/10

Cancellig the terms by 5 = 21/2

So,

➪ 21/2

Dividing by 100 = 21/2 ÷ 100/1

So,

➪ 21/2 ÷ 100/1

Doing reciprocal = 21/2 × 1/100

So,

➪ 21/2 × 1/100

Multiplying = 21/2 × 1/100 = 21/200

So,

➪ 21/200

Final answer:- 21/200

Thus, we GOT the answer.

Answer»

Answer:

The LENGTH of a rectangle is 5 metres less than twice the breadth. If the perimeter is 50

metres, find the length and breadth of the rectangle.

Let the breadth be X

Then length = 2x-5

Perimeter = 50 metres

Length + breadth = (x)+(2x-5)

(2x-5) + x = 25

3x – 5 = 25

3x = 30

x = 10

breadth = 10 metres, length = 15 metres
