the sum of the two natural numbers is 30 the difference between the square of these two numbers is 240 find the numbers

Answer»

Step-by-step EXPLANATION:

LET the no. be X and y

ATQ

x + y = 30

sq. both sides

{x}^{2}  +  {y}^{2}  = 900........... < 1

also

{x}^{2}   -   {y}^{2}  = 240...............2

equ.1 + equ2

{x}^{2}  =  \:  1140

x =  \sqrt{1140}  = 33.76

A farmer connects a pipe of internal diameter 20 cm from a canal into a cylindrical tank in her field which is 10 cm in diameter and 2m deep. If water flows through 3 kmph, in how much time will the tank be filled completely?​

Answer»

The time required to fill the tank completely is 100 minutes.

Step-by-step EXPLANATION:

From question, internal DIAMETER of pipe = 20 cm

Now, the internal radius of pipe = 10 cm = 10/100 m = 1/10 m

From question, the rate of flow of water = 3 km/h = 3000 m/h

Let the time required to fill the tank be x

Volume of water flowing from pipe = Area of cross SECTION × Speed × Time

Volume of water that flows from pipe = πr² × Speed × Time

On substituting the known values, we GET,

Volume of water that flows from pipe = π(1/10)² × 3000 × x

Volume of water that flows from pipe = 30 πt m³

Diameter of the cylinder = 10 m

Radius of the cylinder = 5 m

Depth of the cylinder = 2 m

Volume of tank = πr²h

On substituting the known values, we get,

Volume of tank = π × (5)² × 2

Volume of tank = 50π m³

Volume of water that flows from pipe = Volume of tank

30 πt = 50π

t = 50/30 hours

t = 50/30 × 60 minutes

Therefore, t = 100 minutes

WATER IS POURING INTO A CUBOIDAL RESERVOIR AT THE RATE OF 80 LITRES PER MINUTE.IF THE VOLUME OF RESERVOIR IS 640m3.FIND THE NUMBER OF HOURS IT WILL TAKE TO FILL THE RESERVOIR.

Answer»

Answer:1 HOUR and 20 MIN

Step-by-step explanation:

Rate of water flowing one minute=80 litres

VOLUME of reservoir= 640 m3

Time =volume of reservoir/rate of water

=640/80

=80

Time is 80 MINUTES i.e.1 hour 20 min

Find Dy/DX ifY=sin^-1(2x)

Answer»

Answer:

2 / ( 1 - 4x² )

Step-by-step explanation:

To find -----> DERIVATIVE of Sin⁻¹ ( 2x )

Solution------> We know that,

1) d/dx ( Sin⁻¹x ) = 1 / √1 - x²

2) d/dx ( x ) = 1

ATQ,

y = Sin⁻¹ ( 2x )

Differentiating with respect to x ,

=> dy/dx = d/dx ( Sin⁻¹ 2x )

= [ 1 / √{ 1 - ( 2x )² ] d/dx ( 2x )

= 1 / √( 1 - 4x² ) ( 2 × 1 )

= 2 / √( 1 - 4x² )

Additional information----->

1) d/dx ( xⁿ ) = n xⁿ⁻¹

2) d/dx ( eˣ ) = eˣ

3) d/dx ( aˣ ) = aˣ loga

4) d/dx ( logx ) = 1 / x

5) d/dx ( Sinx ) = Cosx

6) d/dx ( Cosx ) = - Sinx

7) d/dx ( tanx ) = Sec²x

8) d/dx ( Secx ) = Secx tanx

9) d/dx ( Cotx ) = - Cosec²x

10) d/dx ( Cosecx ) = - Cosecx Cotx

The difference between the compound interest and simple interest on a certain sum for3 years at 5% per annum is * 289. Find the sum.​

Answer»

<P>Step-by-step EXPLANATION:

CI = A-P

= P(1+R/100)^n-P

SI= PRT/100

DIFFERENCE = CI-SI

289= {P(1+R/100)^n-P}-{PRT/100}

289=P(1+R/100)^n-1-RT/100

289= P(1+5/100)^3-1-5×3/100

289=p(1+1/20)^3-1-(3/20)

289=p(21/100)^3-17/20
