Answer»

Answer:x-y=14

Step-by-step explanation:

LET x be 5a and y be 3a.

∵x+y=56

∴5a +3a=56

8a=56

a=7

So,

x=5×7=35 and y=3×7=21.

Then,

∴x-y=35-21=14

In an arithmetic sequence ,if 'n'th term is m and 'm'th term is n .Prove that it's common difference is -1.​

Answer»

Answer:

Step-by-step explanation:

d = common difference

Here, NTH term,i.e,a(n)= a+(n-1)d =m [given]. ....(I)

and, MTH term,i.e.,a(m)= a+(m-1)d =n [given]. ....(ii)

SUBTRACTING (i) from (ii),we get-

(n-1)d-(m-1)d=m-n

or, d(n-1-m+1) = m-n

or, d(n-m) = -(n-m)

or, d = -1 ...

Find an equation of the parabola that is symmetric about y-axis has its vertex at theorigin and passes though the point (10, 4). Also show its focus and direction on thegraph

Answer»

GIVEN: vertex at the origin and passes though the point (10, 4).  

To FIND: Find an equation of the parabola ?

Solution:

  • Now we have given that the parabola is symmetric about y-axis so the standard equation will be:

               x² = ± 4ay

  • Now we have given that parabola passes through the point (10, 4) then the Parabola lies on positive y-axis, so:

               x² =  4ay

  • Now the point should satisfy the equation of the parabola:

               10² =  4a(4)

               100 = 16A

               a = 100/16

               a = 25/4

  • So the equation of parabola is x² = 25/4y
  • Now we know that focus of upward opening parabola is:

               4p (y - k) = (x - h)²

               |p| = FOCAL length = 25/16

               4 (25/16) (y - 0) = (x - 0)²

  • So the focus of e is:

               (0, 0+p) = (0, 0+25/16) = (0, 25/16)

  • So the focus is, (0, 25/16)

Answer:

         The equation of parabola is x² = 25/4y and the focus is given by, (0, 25/16).

In a survey, of 410salesperson & 350 construction workers, it's found that 164 of salesperson & 196 of construction workers are overweight. If a person is selected at random from group then what is the probability that:- 1. This person is over weight 2. This person is salesperson, given that the person is over weight. 3. This person is over weight, given that the person is a salesperson. 4. This person is a construction worker, given that the person is not over weight. 5. This person is not over weight, given that the person is a construction worker.

Answer»

Given :  In a survey, of 410 salesperson & 350 construction workers, it's found that 164 of salesperson & 196 of construction workers are overweight. a person is selected at random from group

To find :  1. This person is over weight 2. This person is salesperson, given that the person is over weight. 3. This person is over weight, given that the person is a salesperson. 4. This person is a construction worker, given that the person is not over weight. 5. This person is not over weight, given that the person is a construction worker.

Solution:

Sales person  = 410

Overweight sales person = 164

Not Overweight sales person = 410 - 164  = 246

Construction worker 350

Overweight construction worker 196

Not overweight construction worker = 350 -196 = 154

Total Person = 410 + 350 = 760

Total Overweight = 164 + 196 = 360

Total Not overweight = 246 + 154  = 400

Probability Person is over weight   =  Total overweight / total person =  360/760  

=  9/19

Probability person is salesperson, given that the person is over weight. =  Overweight sales person /  total overweight  =  164/360  

= 41/90

Probability person is over weight, given that the person is a salesperson

= Overweight Sales person / total Sales person

=  164 / 410

= 82/205

Probability  person is a construction worker, given that the person is not over weight.   =  not overweight construction worker / total not overweight

= 196/400

= 49/100

Probability  person is not over weight, given that the person is a construction worker = not overweight construction worker / Construction worker

= 196/350

= 14/25

Find the square of 35 by using column method.verify the result by finding the square using the prime factorisation method

Answer»

Answer:

1225

Step-by-step explanation:

Consider a = 3 and B = 5

From the FORMULA, let us take a^2 as column 1, 2*a*b as column 2 and b^2 as column 3.

(<klux>35</klux>)^2 \\ \\ a = 3,\:\: b = 5\\ \\\begin{tabular}{ c | c | c }CI & CII & CIII \\ \cline{1-3}9 & 30 & 2\underline5 \\ +3& +\underline2 &\\ \cline{1 - 3}\underline{12}& 3\underline2&\end{tabular}

Column 1 = a^2 = 3*3 =9

Column 2 = 2*a*b = 2*3*5= 30

Column 3 = b*b = 5*5 = 25

Underline the unit digit of b^2, add its tens digit to column 2 value.

b^2 = 25

2ab = 30+2=32

Underline the unit digit of 2ab,add its tens and other digit values to a^2.

2ab =32

a^2 = 12

So a^2 will be 12

Write final underlined a^2,2ab,b^2 TOGETHER in a sequence.

1225

∴ Square of 35 is 1225

Three positive integers x , y , z , are in AP such that sum of x, y and z is 33 and product of x, y and z is 1155 then the value of x is

Answer»

In the above Question, the following information is given -

Three POSITIVE integers x , y , Z , are in AP such that sum of x, y and z is 33 and PRODUCT of x, y and z is 1155 .

To find -

The value of x is -

Solution -

Here ,

Three positive integers x , y , z , are in AP such that sum of x, y and z is 33 and product of x, y and z is 1155 .

Let y = y

x = ( y - d )

x = ( y + d )

Now ,

Three positive integers x , y , z , are in AP such that sum of x, y and z is 33

So ,

( y - d ) + y + ( y + d ) = 33

=> 3y = 33

=> y = 11

Product -

=> ( y - d )( y + d ) y

=> ( 11 - d )( 11 + d ) × 11

=> ( 121 - d² ) × 11

=> 1331 - 11d²

But , this is equal to 1155 .

So ,

1331 - 11d² = 1155

=> 11 d² = 176

=> d² = 16

=> d = \neq 4

Thus , x can be 15 as well as 7 .

This is the required answer .

Write some context in which you have used irrational number

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a SIMPLE fraction because there is not a FINITE number of numbers when written as a decimal. Instead, the numbers in the decimal would go on FOREVER, WITHOUT REPEATING.
