prove???

i have already showed that. please specify ur question.

ohh.. that last one

thanks buddy!! you are a genius

hehehe..love to help in math..

Let the first term and the common difference of the A.P areaanddrespectively.

Since the A.P contains 37 terms. So, the middle most term is (37+1)/2 th term = 19thterm.

Thus, three middle most terms of this A.P.are 18th, 19thand 20thterms.

Givena18+a19+a20= 225

⇒ (a+ 17d) + (a+ 18d) + (a+ 19d) = 225

⇒ 3(a+ 18d) = 225

⇒a+ 18d= 75

⇒a= 75 – 18d… (1)According to given information

a35+a36+a37= 429

⇒ (a+ 34d) + (a+ 35d) + (a+ 36d) = 429

⇒ 3(a+ 35d) = 429

⇒ (75 – 18d) + 35d= 143

⇒ 17d= 143 – 75 = 68

⇒d= 4

Substituting the value ofdin equation (1), it is obtained

a= 75 – 18 × 4 = 3

Thus, the A.P. is 3, 7, 11, 15 …

To find the area of rectangle,

area = length*breadth in square units

Like my answer if you find it useful!

Since both points lie on the circle, so, length AO is equal to length BO. since both are the radius of given circle.By applying distance formula,(2-(-1))² + (y-(-3y))²= (5-2)² + (7-(-3y))²⇒9+16y² =9 +(7+3y)²⇒16y²=49+9y²+42y⇒7y²-42y-49=0⇒y²-6y-7=0⇒y²-7y+y-7=0⇒y(y-7)+1(y-7)=0(y-7)=0 or (y+1)=0y=7 or -1

how did the value od OP came

oi pagal question to thik se pahle

matlab kuch bhi question padhiye pahle

T = 2π√1/g

→Δl/l× 100 = 1 (Given) Here we are using Percentage error formula dy/y×100 (OR) dx/x×100 → dl/l× 100 = 1

→ T = 2π√1/g

→ T = 2π(l/g)¹/²

Now, Apply Log on Both sides

→ logT = log2π(l/g)¹/²

→ logT - log2π + log(l/g)¹/²

→ logT = log2π + 1/2log(l/g)

→ logT = log2π + 1/2[log l - log g ]

→ log T = log 2π + 1/2log l - 1/2log g

→ 1/T× dt = 0 + 1/2× 1/l - 1/2× (0)

→ 1/T× dt = 1/2 dl/l

→ dT/T = 1/2 dl/l

→ dT/T× 100 = 1/2 dl/l× 100 { Apply Percentage error formula }

→ dT/T× 100 = 1/2 % { FINAL ANSWER }

200, 208, 216........... 496

a = 200

d = 8

L = 500

=> a +(n-1)d = 496

=> 200 + (n-1)8 = 496

=> (n-1)8 = 296

=> n-1 = 37

=> n = 38

No. of integer between 200 and 500 that is divisible by 8 is 38

This means that there are30 numbers between 10 and 100 that are divisible by 3. 100 divided by 2 is 50. This means that there are50 numbersbetween 1 and 100 that are divisible by 2. However, some of these numbers are counted twice (e.g. 6 is divisible by both 3 and 2)

CARBON Dioxide.The answer is Option a.

thanks for the answer

Let 4x-3/2x+1 = yand 2x+1/4x-3 =1/y since its reciprocalso, y-10(1/y) = 3y-10/y = 3y²-10 = 3yy² - 3y - 10 = 0y² - 5y +2y - 10 = 0y(y-5) + 2(y-5) = 0(y-5)(y+2) = 0y = 5 and y = -2

For y = 5(4x-3)/(2x + 1) = 54x - 3 = 10x + 56x = - 8x = - 4/3

For y = - 2(4x-3)/(2x + 1) = - 24x - 3 = - 4x - 28x = 1x = 1/8

Integers between 200 and 500 divisible by 8 are

208, 216........... 496 its an AP

a = 208

d = 8

L = 500

=> a +(n-1)d = 496

=> 208 + (n-1)8 = 496

=> (n-1)8 = 288

=> n-1 = 36

=> n = 37

No. of integer between 200 and 500 that is divisible by 8 is 37

super thank you

Given: Radius=3cmHeight= 4cmFormula used: Curved surface area of right circular cone=pi*r*LSolution:L=sqroot of h^2+r^2=sqoot(16+9)=5cmArea=3.14*5*3=47.1Area=47.1cmsq

Except (c) all are correct

Explanation:A rectangle is considered a special case of a parallelogram because: A parallelogram is a quadrilateral with 2 pairs of opposite, equal and parallel sides. A rectangle is a quadrilateral with 2 pairs of opposite, equal and parallel sides BUT ALSO forms right angles between adjacent sides.A rhombus is a parallelogram with four congruent sides.A trapezium is NOT a parallelogram because a parallelogram has 2 pairs of parallel sides. But a trapezium only has 1 pair of parallel sides.A kite is a quadrilateral with two adjacent pairs of sides of equal length. A rhombus is a quadrilateral with all sides of equal length. So a rhombus does have two pairs of adjacent sides of equal length and is, therefore, a kite.

It is given that (3k− 2),(4k− 6) and(k+ 2) are three consecutive terms of an AP.

∴(4k− 6)−(3k− 2) =(k+ 2)−(4k− 6)

⇒ 4k− 6− 3k+ 2 =k+ 2− 4k+ 6

⇒k− 4 =−3k+ 8

⇒k+ 3k=8 + 4

⇒ 4k=12

⇒k=3

Hence, the value ofkis 3.

Perimeter of whole figure=4×(4+2+4) cm=4×10 cm=40 cm

LHS:Cosec A + cot A - 1 / cot A - cosec A + 1

we know that,cosec ² A - cot ² A = 1substituting this in the numerator

= cosec A + cot A - (cosec ² A - cot ² A) / (cot A - cosec A + 1)x²-y²= (x+y)(x-y)

= cosec A + cot A - (cosec A + cot A) (cosec A - cot A) / (cot A - cosec A + 1)

= (cosec A + cot A)(1-cosec A + cot A) / (cot A - cosec A + 1)

= cosec A + cot A

= 1/sin A + cos A/sin A

= (1+cos A) / sin A

= RHS

Hence proved

A molecular orbital (MO) is an allowed spatial distribution of electrons in a molecule that is associated with a particular orbital energy. Unlike an atomic orbital (AO), which is centered on a single atom, a molecular orbital extends over all the atoms in a molecule or ion.

3y=ax+7

pass throu 3,4

substituting,

12=3a+7

5=3a=>a=5/3

Given :

a²x + ay = 3

So, x = 1 and y = 2

2a² + a - 3 = 0

2a² - 2a + 3a - 3 = 0

2a( a - 1) + 3 ( a - 1) = 0

( 2a + 3) ( a - 1) = 0

So, a = 1 and a = -3/2
