Answer» Step-by-step explanation: Area of CONE = 792 cm2 ratio = 4:7 = 4x : 7X Π = 22/7 Area of cone = Π RL 792cm2 = 22/7 × 4x × 7x 792cm2 = 22/7 × 28 x2 792cm2 = 616x2/7 792cm2 = 88x2 x2 = 792cm2 /88 x2 = 9cm2 x = √ 9 cm2 x = 3cm RADIUS = 4x = 4× 3 = 12cm

10.

radius and slant height of the cone are in the ratio of 4:7 curved surface area is 792 CM square find its radius also find the total surface area

Answer»

Step-by-step explanation:

Area of CONE = 792 cm2

ratio = 4:7

= 4x : 7X

Π = 22/7

Area of cone = Π RL

792cm2 = 22/7 × 4x × 7x

792cm2 = 22/7 × 28 x2

792cm2 = 616x2/7

792cm2 = 88x2

x2 = 792cm2 /88

x2 = 9cm2

x = √ 9 cm2

x = 3cm

RADIUS = 4x = 4× 3 = 12cm

29.	A and b are the zeros of 4x^2-5x-1,then a^2b-b^2a=
Answer» Answer: - √41 / 16 Step-by-step EXPLANATION: Given-----> a and b are zeroes of ( 4x² - 5x - 1 ) To find -----> Value of ( a²b - b²a ) Solution-----> ATQ, 4x² - 5x - 1 has zeroes as a and b , We know that, Sum of zeroes = - Coefficient of x / Coefficient of x² => a + b = - ( - 5 ) / 4 => a + b = 5 / 4 Product of zeroes = Constant term / Coefficient of x² AB = - 1 / 4 Now, a²b - b²a = ab ( a - b ) = ab √( a - b )² We know that, ( a - b )² = ( a + b )² - 4ab , putting it , we get a²b - b²a = ab √{ ( a + b )² - 4ab } = ( -1/4 ) √{ ( 5/4 )² - 4 ( -1/4 ) } = ( -1/4 ) √{ ( 25/16) + 1 } = ( -1/4 ) √{ ( 25 + 16) / 16 } = ( -1/4 ) √( 41/16) = ( -1/4 ) √41/ 4 = - √41 /16

29.

A and b are the zeros of 4x^2-5x-1,then a^2b-b^2a=

Answer»

Answer:

- √41 / 16

Step-by-step EXPLANATION:

Given-----> a and b are zeroes of ( 4x² - 5x - 1 )

To find -----> Value of ( a²b - b²a )

Solution-----> ATQ,

4x² - 5x - 1 has zeroes as a and b ,

We know that,

Sum of zeroes

= - Coefficient of x / Coefficient of x²

=> a + b = - ( - 5 ) / 4

=> a + b = 5 / 4

Product of zeroes

= Constant term / Coefficient of x²

AB = - 1 / 4

Now,

a²b - b²a = ab ( a - b )

= ab √( a - b )²

We know that,

( a - b )² = ( a + b )² - 4ab , putting it , we get

a²b - b²a = ab √{ ( a + b )² - 4ab }

= ( -1/4 ) √{ ( 5/4 )² - 4 ( -1/4 ) }

= ( -1/4 ) √{ ( 25/16) + 1 }

= ( -1/4 ) √{ ( 25 + 16) / 16 }

= ( -1/4 ) √( 41/16)

= ( -1/4 ) √41/ 4

= - √41 /16

Tom's WORK in ONE day = 1/16

Tom and John's work in one day = 1/10

50.	If the number a b c d re form an AP then find the value of a-4b+6c-4d+e= ?
Answer» Answer: 0 Step-by-step explanation: The AP is : a b c d e Let the FIRST TERM be of the form A ; and the difference is D . Then Let the AP be in the form :- A-2D (a) A-D(b) A(c) A+D(d) A+2D(e) Now using these terms in the value a-4b+6c-4d+e =A-2D-4(A-D)+6(A)-4(A+D)+(A+2D) After EXPANDING , we get =A-4A+6A-4A+A =2A-8A+6A =8A-8A =0

If the number a b c d re form an AP then find the value of a-4b+6c-4d+e= ?

Answer»

Answer:

0

Step-by-step explanation:

The AP is : a b c d e

Let the FIRST TERM be of the form A ; and the difference is D . Then

Let the AP be in the form :-

A-2D (a) A-D(b) A(c) A+D(d) A+2D(e)

Now using these terms in the value

a-4b+6c-4d+e

=A-2D-4(A-D)+6(A)-4(A+D)+(A+2D)

After EXPANDING , we get

=A-4A+6A-4A+A

=2A-8A+6A

=8A-8A

=0
