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. |

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.. Follow and mark brainliest please..

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,
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 cmNow, ✭ Curved surface area (C.S.A) = 2πrh ✭ Where,
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,
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 _______________________________ |
