While catching a fast moving cricket ball , a fielder in the ground gradually pulls his hand backwards with the moving ball, In doing so, the fielder increases the time during which the high velocity of the moving ball descrease to zero. Thus, the accleration of the ball is descreased and therefore the impact of catching the fast moving ball is also reduced.

If the ball stopped suddenly then it's high velocity is descreases to zero in a very short interval of time.

Thus, the rate of change of momentum of the ball will be large. Therefore, a large force would have to be applied for holding the catch that may hurt the palm of the fielder.

Diameter of the cylindrical tank = 4 m

radius of the cylindrical tank = 2 m

height of the tank = 10 m

Diameter of the cylindrical pipe = 10 cm

radius of the cylindrical pipe = 10/2 = 5 cm

= 5/100 m

speed of water = 2.5 km/hr

1000 m = 1 km

= 2.5 x 1000

= 2500 m/hr

Volume of water discharged from

the cylindrical pipe = (1/2) Volume of cylindrical tank

Area of cross sectionxtimexspeed = (1/2)Πr² h

Πr²xtimexspeed = (1/2)Πr² h

(5/100)²xtimex2500 = (1/2)(2)² (10)

(5/100)x(5/100)xtimex2500 = (1/2)x(2)x2x(10)

Time =2x10x(100/5)x(100/5)x(1/2500)

Time =80/25

= 3.2 hour

1 hour = 60 minute

= 192 minute

= 180 + 12

3 hour and 12 minute

Therefore time taken to empty the half of the tank is 3 hour and 12 minute

Let the number be x.-3/4 - x = - 11/14That is x = 11/14 - 3/4 find Lcm and find ans :)

the answer is 10 a whole number 2 by 5

ye hi mera answer hai

Let the four consecutive numbers in AP be;

(a - 3d), (a - d), (a + d) and (a + 3d)

So, according to the question

a - 3d + a - d + a + d + a + 3d = 32

4a = 32

a = 8

Now,

(a - 3d)(a + 3d) / (a - d)(a + d) = 7/15

15(a² - 9d²) = 7(a² - d²)

15a² - 135d² = 7a² - 7d²

8a² = 128d²

Putting the value of a = 8, we get

d² = 4

d = ±2

So, the four consecutive numbers are 2, 6, 10, 14 or 14, 10, 6, 2

yes it is right

I took theta on the place of alpha don't worry about that

(sec8θ-1)/(sec4θ-1)=(1/cos8θ-1)/(1/cos4θ-1)=[(1-cos8θ)/cos8θ]/[(1-cos4θ)/cos4θ]=(2sin²4θ/cos8θ)/(2sin²2θ/cos4θ) [∵, 1-cos2θ=2sin²θ]=2(2sin2θcos2θ)²/cos8θ×cos4θ/2sin²2θ=4cos²2θcos4θ/cos8θRHStan8θ/tan2θ=(sin8θ/cos8θ)/(sin2θ/cos2θ)=2sin4θcos4θ/cos8θ×cos2θ/sin2θ=2.2sin2θcos2θcos4θ/cos8θ×cos2θ/sin2θ=4cos²2θcos4θ/cos8θ∴, LHS=RHS(Proved)

hello game hacker how are you

think so ,should be added XX+7/15=9/5X =9/5-7/15 =27-7/15 =20/15 =4/3 is answer

2k= 10 k = 5

a= -5

since diagonals are equal in the rectangle , so their bisected parts are also equal

=> 2y-9 = y+1=> y = 1+9= 10

so, the value of y = 10.

For AP1/2q, (1-2q)/2q, (1-4q)/2q,...

Common difference= (1-2q)/2q - 1/2q= (1-2q - 1)/2q= - 2q/2q= - 1

Therefore for given AP common difference = - 1

Thanx

Common difference of an AP= Difference of two consecutive terms i.e. second term-first term= ((1-p)/p)-1/p=(1-p-1)/p=-p/p=-1

tq

Comman ratio will be= ( next term- previous term)1-6q/3q-(1/3q)= -2Please like the solution 👍 ✔️

_40 +/- √40×40_ 4×16×25/2×16

We need to select one pair from the top list and one pair from the bottom list. It is usually smart to start with the pairs that have two numbers close in value. So let's try(5,5)with(4,4).

(4x+5)(4x+5)=16x²+20x+20x+25

=16x²+40x+25

This one worked!

Hence, the factored form is:

(4x+5)(4x+5)=(4x+5)²

Solving:

(4x+5)²=0

4x+5=0

4x=−5

x=−5/4

so both are correct answer s

We know that diagonal of square =√2×sideSo;√2×side= 7 cm⇒Side=7√2=7√2×√2/√2=7/2√2=3.5×1.41= 4.935 cm≈5 cmSo, each side of square is 4.935 cm and each angle is of 90 degree.Now we construct a square of diagonal 7 cm and each side of 5 cmSTEP I : Draw a line segment PQ = 5 cm.STEP II: Take Q as a point and draw a line segment QR = 5 cm such that∠PQR=90°STEP III: Take R as a point and draw a line segment RS = 5 cm such that∠QRS=90°STEP III: Join SP. and PR.

This forms a square PQRS having diagonal PR = 7 cm and each side of 5 cm.

Yes its rightadditive inverseof 8 is -8 as8-8= 0thanks

83 is the additive inverse

additive inverse of 9 is -9 multiplicative inverse of 9 is 1/9

additive inverse of 1/5 is -1/5so1/5 + (-1/5) = 0

its incorrect

ya

can you solve again

2x + 3y = 4 .....(1)4x - 3y = 9 .......(2)

Eliminating y by adding (1) and (2)6x = 13x = 13/6

3y = 4 - 2x3y = 4 - 2 × 13/6 3y = 4 -13/33y = (12-13)/33y = -1/3y = -1/9
