10.

The area of a square field is 576 m². A rectangularfield whose length is twice its breadth has itsperimeter equal to the perimeter of the squarefield. Find the area of the rectangular field.Plz send only answer

Answer»

Answer:

512 m

Step-by-step explanation:

area of square = 576 m^2

s^2 = 576

s = square root of 576

s = 24

perimeter of square = 4 * 24

= 96 m

l = 2b

2(l+b) = 96

2(2 b + b) = 96

3b = 96/2= 48

b = 48/3

b = 16m

l = 2b

= 2* 16

l = 32

A= l*b

= 32 * 16

= 512 m

14.	The sum of q number and it's reciprocal is 3, find the number
Answer» Answer: Reciprocal means 1 DIVIDED by that number. For example, the reciprocal of 2 is 1/2. So lets call the number we are trying to find x. x + 1/x = 3 so, now rearrange x and 1/x so they have the same denominator (the bottom part of the fraction). To do this, we can say that x = x/1. TIMES the top and bottom by x. That gives x2/x. so... x2/x + 1/x = 3 now we can add the fractions. (x2+1) / x = 3 Times each side of the equation by x. x2+1 = 3x x2 -3x +1 = 0 This is a quadratic equation that we can solve, to find x. Then you can use the quadratic formula to find x. If you want to see how this works, go to: but it gives us the answers: x = (3+sqrt5)/2 or (3-sqrt5)/2 (sqrt 5 means the square root of 5) which come out as 2.618 (to 3 decimal places) and 0.382 (to 3 decimal places) and you can check: when you add them to their reciprocal, you get 3

14.

The sum of q number and it's reciprocal is 3, find the number

Answer»

Answer:

Reciprocal means 1 DIVIDED by that number. For example, the reciprocal of 2 is 1/2.

So lets call the number we are trying to find x.

x + 1/x = 3

so, now rearrange x and 1/x so they have the same denominator (the bottom part of the fraction). To do this, we can say that x = x/1. TIMES the top and bottom by x. That gives x2/x.

so...

x2/x + 1/x = 3

now we can add the fractions.

(x2+1) / x = 3

Times each side of the equation by x.

x2+1 = 3x

x2 -3x +1 = 0

This is a quadratic equation that we can solve, to find x.

Then you can use the quadratic formula to find x. If you want to see how this works, go to:

but it gives us the answers:

x = (3+sqrt5)/2

or (3-sqrt5)/2

(sqrt 5 means the square root of 5)

which come out as 2.618 (to 3 decimal places)

and 0.382 (to 3 decimal places)

and you can check: when you add them to their reciprocal, you get 3

The nth term of an A.P. is given by An =-4n+15. Find the 15th term and the common difference of the A.P. (Ans: a15 = -45, d = -4)

Answer»

Answer:

15 th TERM = - 45

common DIFFERENCE = - 4

Step-by-step explanation:

=> An = - 4n + 15

=> a + ( n - 1 ) d = - 4n + 15

=> a + ( n - 1 ) d = 11 + ( n - 1 ) (-4)

COMPARING LHS and RHS

a = 11 and d = - 4

15th term = 11 + 14x(-4)
