10.	The 23rd term and 37th term of an AP are 54, 96 Find 30th term
Answer» EXPLANATION. 23rd term of an A.P. = 54. 37th term of an A.P. = 96. As we KNOW that, General term of an A.P. ⇒ Tₙ = a + (n - 1)d. ⇒ T₂₃ = a + (23 - 1)d. ⇒ T₂₃ = a + 22D. ⇒ a + 22d = 54. ⇒ (1) ⇒ T₃₇ = a + (37 - 1)d. ⇒ T₃₇ = a + 36d. ⇒ a + 36d = 96. ⇒ (2). From equation (1) & (2), we get. ⇒ a + 22d = 54. ⇒ a + 36d = 96. We get. ⇒ - 14d = - 42. ⇒ 14d = 42. ⇒ d = 42/14. ⇒ d = 3. Put the value of d = 3 in equation (1), we get. ⇒ a + 22d = 54. ⇒ a + 22(3) = 54. ⇒ a + 66 = 54. ⇒ a = 54 - 66. ⇒ a = -12. To FIND 30th term of an A.P. ⇒ T₃₀ = a + (30 - 1)d. ⇒ T₃₀ = a + 29d. ⇒ T₃₀ = -12 + 29(3). ⇒ T₃₀ = -12 + 87. ⇒ T₃₀ = 75. MORE INFORMATION. Supposition of terms in A.P. (1) = Three terms as : a - d, a, a + d. (2) = Four terms as : a - 3d, a - d, a + d, a + 3d. (3) = Five terms as : a - 2d, a - d, a, a + d, a + 2d.

10.

The 23rd term and 37th term of an AP are 54, 96 Find 30th term

Answer»

EXPLANATION.

23rd term of an A.P. = 54.

37th term of an A.P. = 96.

As we KNOW that,

General term of an A.P.

⇒ Tₙ = a + (n - 1)d.

⇒ T₂₃ = a + (23 - 1)d.

⇒ T₂₃ = a + 22D.

⇒ a + 22d = 54. ⇒ (1)

⇒ T₃₇ = a + (37 - 1)d.

⇒ T₃₇ = a + 36d.

⇒ a + 36d = 96. ⇒ (2).

From equation (1) & (2), we get.

⇒ a + 22d = 54.

⇒ a + 36d = 96.

We get.

⇒ - 14d = - 42.

⇒ 14d = 42.

⇒ d = 42/14.

⇒ d = 3.

Put the value of d = 3 in equation (1), we get.

⇒ a + 22d = 54.

⇒ a + 22(3) = 54.

⇒ a + 66 = 54.

⇒ a = 54 - 66.

⇒ a = -12.

To FIND 30th term of an A.P.

⇒ T₃₀ = a + (30 - 1)d.

⇒ T₃₀ = a + 29d.

⇒ T₃₀ = -12 + 29(3).

⇒ T₃₀ = -12 + 87.

⇒ T₃₀ = 75.

MORE INFORMATION.

Supposition of terms in A.P.

(1) = Three terms as : a - d, a, a + d.

(2) = Four terms as : a - 3d, a - d, a + d, a + 3d.

(3) = Five terms as : a - 2d, a - d, a, a + d, a + 2d.

41.	The coefficient of ax²+bx+c=0 are obtained by throwing a die find the probability of the equation has real and equal roots , real and unequal roots , not real
Answer» Answer: FIRST let's talk about real ROOTS. Since each of the coefficients a, b, and c can take the values from 1 to 6 Therefore,total number of equations = 6 6 6 = 216. The roots of the equation ax2 + bx + c = 0 will be real, if b2 - 4 ac 0 b2 4 ac. The favourable number of elementary events can be enumerated as under: ac a c 4ac b(so that b2 4ac) Number of ways 1 1 1 4 2,3,4,5,6 1 5 = 5 2 1,2 2,1 8 3,4,5,6 2 4 = 8 3 1,3 3,1 12 4,5,6 2 3 = 6 4 1,4,2 4,1,2 16 4,5,6 3 3 = 9 5 1,5 5,1 20 5,6 2 2 = 4 6 6,2,3 1,3,2 24 5,6 4 2 =8 7 ac is not possible 0 8 2,4 4,2 32 6 2 1 = 2 9 3 3 36 6 1 Total = 43 Since b2 4 ac and the maximum value of b2 is 36, therefore ac = 10 , 11,12 ... etc. is not possible.Therefore,we reject such values. Therefore, Total number of favourable elementary events = 43. Hence, REQUIRED probability= 43/216 Now, Real and equal ⇒b² −4ac=0 Each coefficients is an integer, So we consider the following cases b=1⇒ 41 =ac No integral value of a and c b=2⇒1=ac∴(1,1) b=3⇒ 29 =ac No integral value of a and c b=4⇒4=ac∴(1,4),(2,2),(4,1) b=5⇒ 225 =ac No integral value of a and c b=6⇒9=ac∴(3,3) Thus we have 5 favorable ways for b=2,4,6 Total number of equation is 6.6.6=216 Therefore required probability is 5/216 Now Real and Unequal.. its simple Real - Equal So 43/216 - 5 /216 = 38/216 For not real, subtract total possibilities from real ones. 216-43 = 173/216 I have tried my best and hope it's correct..

The coefficient of ax²+bx+c=0 are obtained by throwing a die find the probability of the equation has real and equal roots , real and unequal roots , not real

Answer»

Answer:

FIRST let's talk about real ROOTS.

Since each of the coefficients a, b, and c can take the values from 1 to 6

Therefore,total number of equations = 6 6 6 = 216.

The roots of the equation ax2 + bx + c = 0 will be real, if b2 - 4 ac 0 b2 4 ac.

The favourable number of elementary events can be enumerated as under:

ac a c 4ac b(so that b2 4ac) Number of ways

1 1 1 4 2,3,4,5,6 1 5 = 5

2 1,2 2,1 8 3,4,5,6 2 4 = 8

3 1,3 3,1 12 4,5,6 2 3 = 6

4 1,4,2 4,1,2 16 4,5,6 3 3 = 9

5 1,5 5,1 20 5,6 2 2 = 4

6 6,2,3 1,3,2 24 5,6 4 2 =8

7 ac is not possible 0

8 2,4 4,2 32 6 2 1 = 2

9 3 3 36 6 1

Total = 43

Since b2 4 ac and the maximum value of b2 is 36, therefore ac = 10 , 11,12 ... etc. is not possible.Therefore,we reject such values.

Therefore, Total number of favourable elementary events = 43.

Hence, REQUIRED probability= 43/216

Now, Real and equal ⇒b² −4ac=0

Each coefficients is an integer, So we consider the following cases

b=1⇒ 41 =ac No integral value of a and c

b=2⇒1=ac∴(1,1)

b=3⇒ 29 =ac No integral value of a and c

b=4⇒4=ac∴(1,4),(2,2),(4,1)

b=5⇒ 225 =ac No integral value of a and c

b=6⇒9=ac∴(3,3)

Thus we have 5 favorable ways for b=2,4,6

Total number of equation is 6.6.6=216

Therefore required probability is

5/216

Now Real and Unequal.. its simple Real - Equal

So 43/216 - 5 /216 = 38/216

For not real, subtract total possibilities from real ones.

216-43 = 173/216

I have tried my best and hope it's correct..

Solution: Let's understand the concept first!

TSA of cylinder is 4144.80 cm² & its height is 13 cm. Find CSA & Volume.

Answer»

Given:

✰ Total surface area of cylinder (T.S.A) = 4144.80 cm²

✰ Height of cylinder (h) = 13 cm

To find:

✠ Curved surface area (C.S.A) of cylinder.

✠ Volume ( V ) of cylinder.

Solution:

Let's understand the concept first! We will find out the radius of a circle by using formula to calculate total surface PUTTING, the values in the formula and then doing the required calculations. After FINDING out the radius of a circle, we will use formula of curved surface area and volume respectively to find them.

Let's find out...!

✭ Total surface area (T.S.A) = 2πR (h + r) ✭

Where,

r is the radius of the cylinder.
h is the the height of the cylinder.

Putting the values in the formula, we have:

➛ 4144.80 = 2 × 22/7 × r ( 13 + r )

➛ 4144.80 = 2 × 22/7 × 13r + r²

➛ 4144.80 = 44/7 × 13r + r²

➛ 13r + r² = 4144.80 × 7/44

➛ 13r + r² = 659.4

➛ r + r² = 659.4/13

➛ 2r² = 50.7231

➛ r² = 50.7231/2

➛ r² = 25.4

➛ r = √25.4

➛ r ≈ 5.04 cm

Now,

✭ Curved surface area (C.S.A) = 2πrh ✭

Where,

r is the radius of the cylinder.
h is the the height of the cylinder.

Putting the values in the formula, we have:

➤ Curved surface area (C.S.A) = 2 × 22/7 × 5.04 × 13

➤ Curved surface area (C.S.A) = 2 × 22/7 × 65.52

➤ Curved surface area (C.S.A) = 44/7 × 65.52

➤ Curved surface area (C.S.A) = 2882.88/7

➤ Curved surface area (C.S.A) = 411.84 cm²

∴ Curved surface area (C.S.A) of cylinder = 411.84 cm²

✭ Volume ( V ) of cylinder = πr²h ✭

Where,

r is the radius of the cylinder.
h is the the height of the cylinder.

Putting the values in the formula, we have:

➤ Volume ( V ) of cylinder = 22/7 × 25.4 × 13

➤ Volume ( V ) of cylinder = 22/7 × 330.2

➤ Volume ( V ) of cylinder = 7264.4/7

➤ Volume ( V ) of cylinder ≈ 1037.8 cm³

∴ Volume ( V ) of cylinder = 1037.8 cm³
