This is the representation of 7/4

We can do it by using PythagorasTheorem.

We can write√10 =√(9 + 1)

=> √10 =√(3^2+ 1)

Construction

1. Take a line segment AO = 3 unit on thex-axis. (consider 1 unit = 2cm)

2. Draw a perpendicular on O and draw a line OC = 1 unit

3. Now join AC with √10.

4. Take A ascenter and AC as radius, draw an arc which cuts the x-axis at point E.

5. The line segment AC represents √10 units.

Given :Diameter of cylinder = 12 cmSo, the radius = 12/2 = 6 cmHeight of the cylinder = 15 mLet 'h' be the total height and 'r' the radius of the hemisphere respectively.Now,Radius of hemisphere = Radius of the coneFrom the given information.h = 3rVolume of cylinder = Volume of hemisphere + Volume of coneπr1²h = 12× (2/3πr³ + 1/3πr²h)⇒π(6)²*15 = 12π× {2/3r³ + 1/3r²(3r)}⇒ 36*15 = 12× (2/3r³ + r³)⇒ 36*15 = 12× (5r³/3)⇒ 540 = (60r³/3)⇒ 540 = 20r³⇒ r³ = 540/20⇒ r³ = 27⇒ r =∛27r = 3 cmNow, the radius of the hemisphere is 3 cm.Therefore, height of the toy = 3× 3 = 9 cm

Given that (a-b) x + (a + b)y = a2 - 2ab - b2 -------------(1)

(a+b) x+ (a+b)y = a2 + b2 -------------(2)

Substracting (2) from (1) we get

-2bx = -2ab

=2b2 x = a + b

Subsitute x in equation (2) we get y = - 2ab / ( a + b).

Multiply with -1.The sign for every element will modify.

where is wrong in my answer please check

Two numbers are co prime when HCF is 1All three options are correct as thier HCF is 1

a) HCF ( 2 and 7 ) = 1

b) HCF(9,22) = 1

c) HCF (7,24) = 1

thanks

(B) 7

(5/8) × 24 = (15/7) × ? 15 = (15/7) × ? ? = 15 × (7/15) = 7

438 oranges price = 1384.08 one orange price=1384.08/438=3.16 rupies8 dursen = 12*8=96so 96 oranges price =96*3.16=303.36 rupies

438 ka price : 1384.08 to 1 ka : 1384.08÷438 to 8 dozen ka: 1384.08/438×8×12= 303.36 yani 300

12*8 = 96 so 96*3.16=303.36 rupees

438 🍊 orange=1384.0812×8=9696×3.16=303.36 rupeesanswer b. =300 wright

but the numbers are 2, 17, 20, 125 so how it can be 5, 12 and all

Let rational number be x

Then,x * 2/3 = 2x/3

x * 2/9 = 2x/9

2x/9 - 2x/3 = - 3 1/5

2x(1 - 3)/9 = - 16/5

-4x/9 = - 16/5

x = 16/5 * 9/4

x = 9*4/5 = 36/5

Therefore,Rational number = 36/5

a)8/19b) is notc) 7/9d) is note)6/12f)8 /17

3/5 and 2/33*3/5*3 and 2*5/3*5=9/15and 10/15hence 5 rational number are9.1/15,9.2/15,9.3/15,9.4/15,9.5/15

2.1/3; 2.2/3; 3/3; 3.1/3; 3.3/3

thank u

Answer:

Step one is to rewrite the function as a rational exponentf(x)=sin(x)^(1/2)

Explanation:

After you have your expression in that form, you can differentiate it using theChain Rule:

In your case:u^(1/2)→(1/2)sin(x)^(−1/2)⋅d/dxsin(x)

Then,1/2sin(x)^(-1/2)⋅cos(x)which is your answer

thank you

(9-2)^2=49; (8-5)^2=9; (6-4)^2=4 then (7-6)^2=1

6-4=2x2=4,8-5=3x3=9,9-2=7x7=49,then 7-6=1x1=1 Ans.

x/y = (-2/3)^9÷ (-2/3)^8 = (-2/3)^(9-8) = -2/3

so (x/y)² = (-2/3)² = 4/9

41 is the best answer

49 is correct answer

2.

answer is clearly so plzzzzzzz send me answer clearly plzzzzzzz

Equation of tangent is given by = (y-y1)= M(x-x1)M=dy/dx of the curvexy=10y=10/xdy/dx = (-10/x^2 ) at x = 2M= -10/4=-5/2 so we get the slope nowy1=5 x1 =2y-y1=m(x-x1) be equation of tangenty-5=-5/2(x-2)y+5/2x -10 = 02y + 5x - 20 =0 is the equation of tangent now for equation of normalwe need Mn by using this equationM*Mn = -1Mn *-5/2 =-1Mn =2/5 for equation of tangenty-y1 =Mn (x-x1)y-5 = 2/5(x-2)y-2/5 x -5 + 4/5 = 05y - 2x -21 = 0 be the equation of tangent

Since, length of subnormal is directly proportional to cube of y, hence, it is directly proportional to cube of abscissa.

it is right.thanks a lot
