2. Find the roots of the following quadratic equations by factorisation:
100x2 - 20x + 1 = 0

Answers

Answer 1

Answer:

x = [tex]\frac{1}{10}[/tex]

Step-by-step explanation:

Given

100x² - 20x + 1 = 0 ← this is a perfect square

(10x - 1)² = 0, thus

10x - 1 = 0 ( add 1 to both sides )

10x = 1 ( divide both sides by 10 )

x = [tex]\frac{1}{10}[/tex]

Answer 2

Answer:

Step-by-step explanation:

100x^2-20x+1=0

100x^2-(10+10)X+1=0

100x^2-10x-10x+1=0

10x(10x-1)-1(10x-1)=0

(10x-1)(10x-1)=0

So roots are X=1/10,1/10

what is the difference between 3/8 and 61/64 redosed

Answers

Answer:

Distance between points =  [tex]37/64\\[/tex]

Step-by-step explanation:

This is a relatively simple problem. Here we have to find the distance between two points on the number line.

The given two numbers are fractions and to find the difference between these two numbers, we have to make their denominators common.

One has denominator as 8 and the other as 64.

We make the common denominator as 64.

Then the fractions 24/64 are 61/64  and .

The distance between the two points = 61/64  - 24/64  

                                = 37/64

Step-by-step explanation:

Step 1: Define

f(x) = 5x - 12

f(2) is x = 2

Step 2: Solve

Substitute:                         f(2) = 5(2) - 12Multiply:                             f(2) = 10 - 12Subtract:                            f(2) = -2

Answer:

f ( 2 ) = - 2

Step-by-step explanation:

Step 1:

f ( x ) = 5x - 12            Function

Step 2:

f ( 2 ) = 5 ( 2 ) - 12          Input x

Answer:

0.036%

Step-by-step explanation:

80/100 = 80% ( wait that's not the reason. )

Here, 80/100 = 0.8 ⋅ 4.5 = 3.6 and if you move

Answers

Answer:

multiple of 4 : 8, 12

not a multiple of 4 : 2 , 18

prime : 3, 11

not prime : 9, 15

Step-by-step explanation:

First you need to know even number.

even number is (2,8,12,18 )

next odd number (3,9,11,15)

after that find number that is multiple of 4.

multiple of 4 is 4, 8,12,16,20,24,28 and so on

so its the number of multiple of 4 is ( 8 and 12)

and the number that is not a multiple of 4 is (2,18)

next odd number, odd number is ( 3,9,11,15)

next you should know prime number,

prime number is 3, 5,7,11,13,17,19 .....

so the answer for prime number for odd number is

( 3 and 11)

next is not prime number (9 and 15)

The answer is 7.

First, substitute the S for the 5 and you will have 9-8/4.
We know that fractions is just division so divide 8 and 4 to get 2. Then, subtract 2 from 9 to get 7.
