Answer» Answer: While the FACT that giraffes have the same number of cervical VERTEBRAE as humans is interesting, it's actually not that unusual. The vast majority of mammals have seven and the SIZE of the vertebrae is the thing that DIFFERS, not the number.

Answer» Answer: ove that the sum Sn of n terms of an Arithmetic PROGRESS (A.P.) whose first term ‘a’ and COMMON difference ‘d’ is S = n2[2A + (n - 1)d] Or, S = n2[a + l], where l = last term = a + (n - 1)d Proof: Suppose, a1, a2, a3, ……….. be an Arithmetic Progression whose first term is a and common difference is d. Then, a1 = a a2 = a + d a3 = a + 2d a4 = a + 3D ……….. ……….. an = a + (n - 1)d Now, S = a1 + a2 + a3 + ………….. + an−1 + an S = a + (a + d) + (a + 2d) + (a + 3d) + ……….. + {a + (n - 2)d} + {a + (n - 1)d} ……………….. (i) By writing the terms of S in the reverse order, we get, S = {a + (n - 1)d} + {a + (n - 2)d} + {a + (n - 3)d} + ……….. + (a + 3d) + (a + 2d) + (a + d) + a Adding the corresponding terms of (i) and (ii), we get 2S = {2a + (n - 1)d} + {2a + (n - 1)d} + {2a + (n - 1)d} + ………. + {a + (n - 2)d} 2S = n[2a + (n -1)d ⇒ S = n2[2a + (n - 1)d] Now, l = last term = nth term = a + (n - 1)d Therefore, S = n2[2a + (n - 1)d] = n2[a {a + (n - 1)d}] = n2[a + l]. We can also find find the sum of first n terms of an Arithmetic Progression according to the process below. Suppose, S denote the sum of the first n terms of the Arithmetic Progression {a, a + d, a + 2d, a + 3d, a + 4d, a + 5d ……………...}. Now nth term of the given Arithmetic Progression is a + (n - 1)d Let the nth term of the given Arithmetic Progression = l Therefore, a + (n - 1)d = l Hence, the term preceding the last term is l – d. The term preceding the term (l - d) is l - 2d and so on. Therefore, S = a + (a + d) + (a + 2d) + (a + 3d) + …………………….. to n tems Or, S = a + (a + d) + (a + 2d) + (a + 3d) + …………………….. + (l - 2d) + (l - d) + l ……………… (i) Writing the above series in reverse order, we get S = l + (l - d) + (l - 2d) + ……………. + (a + 2d) + (a + d) + a………………(ii) Adding the corresponding terms of (i) and (ii), we get 2S = (a + l) + (a + l) + (a + l) + ……………………. to n terms ⇒ 2S = n(a + l) ⇒ S = n2(a + l) ⇒ S = Numberofterms2 × (First term + Last term) …………(iii) ⇒ S = n2[a + a + (n - 1)d], Since last term l = a + (n - 1)d ⇒ S = n2[2a + (n - 1)d] please mark me as brain list

soon w The sum of first in terms of an A.P, whose first term is 'aand last term is 1 A) Sa+(n+1)d) B) S. -- 11 C) 5122*(n+1)] DS

Answer»

Answer:

ove that the sum Sn of n terms of an Arithmetic PROGRESS (A.P.) whose first term ‘a’ and COMMON difference ‘d’ is

S = n2[2A + (n - 1)d]

Or, S = n2[a + l], where l = last term = a + (n - 1)d

Proof:

Suppose, a1, a2, a3, ……….. be an Arithmetic Progression whose first term is a and common difference is d.

Then,

a1 = a

a2 = a + d

a3 = a + 2d

a4 = a + 3D

………..

an = a + (n - 1)d

Now,

S = a1 + a2 + a3 + ………….. + an−1 + an

S = a + (a + d) + (a + 2d) + (a + 3d) + ……….. + {a + (n - 2)d} + {a + (n - 1)d} ……………….. (i)

By writing the terms of S in the reverse order, we get,

S = {a + (n - 1)d} + {a + (n - 2)d} + {a + (n - 3)d} + ……….. + (a + 3d) + (a + 2d) + (a + d) + a

Adding the corresponding terms of (i) and (ii), we get

2S = {2a + (n - 1)d} + {2a + (n - 1)d} + {2a + (n - 1)d} + ………. + {a + (n - 2)d}

2S = n[2a + (n -1)d

⇒ S = n2[2a + (n - 1)d]

Now, l = last term = nth term = a + (n - 1)d

Therefore, S = n2[2a + (n - 1)d] = n2[a {a + (n - 1)d}] = n2[a + l].

We can also find find the sum of first n terms of an Arithmetic Progression according to the process below.

Suppose, S denote the sum of the first n terms of the Arithmetic Progression {a, a + d, a + 2d, a + 3d, a + 4d, a + 5d ……………...}.

Now nth term of the given Arithmetic Progression is a + (n - 1)d

Let the nth term of the given Arithmetic Progression = l

Therefore, a + (n - 1)d = l

Hence, the term preceding the last term is l – d.

The term preceding the term (l - d) is l - 2d and so on.

Therefore, S = a + (a + d) + (a + 2d) + (a + 3d) + …………………….. to n tems

Or, S = a + (a + d) + (a + 2d) + (a + 3d) + …………………….. + (l - 2d) + (l - d) + l ……………… (i)

Writing the above series in reverse order, we get

S = l + (l - d) + (l - 2d) + ……………. + (a + 2d) + (a + d) + a………………(ii)

Adding the corresponding terms of (i) and (ii), we get

2S = (a + l) + (a + l) + (a + l) + ……………………. to n terms

⇒ 2S = n(a + l)

⇒ S = n2(a + l)

⇒ S = Numberofterms2 × (First term + Last term) …………(iii)

⇒ S = n2[a + a + (n - 1)d], Since last term l = a + (n - 1)d

⇒ S = n2[2a + (n - 1)d]

But, this contradicts the fact that a and b are co-prime. This MEANS that our assumption is not correct. Hence, 3 is an irrational number.

8694.	The sum of first 10 terms of an Arithmetic Progression is 55 and the sum of first 9 terms of the same arithmetic progression is 45. Then its 10 term is
Answer» Answer: 10 Step-by-step explanation: For first 10 terms: ⇒ 1st term + 2nd term + 3rd term + ... 10TH term ⇒ sum of first 9 term + 10th term Given, S₉ = 45, S₁₀ = 55 ⇒ S₁₀ = S₉ + T₁₀ ⇒ 55 = 45 = T₁₀ ⇒ 10 = T₁₀ Hence the 10th term is 10 Technique 2: S₁₀ = (10/2)[2a + 9d] = 10a + 45d = 55 S₉ = (9/2)[2a + 8d] = 9A + 36D = 45 SOLVING these equations, we get a = 1, and d = 1 Hence 10th term = a + 9d = 1 + 9(1) = 10

8694.

The sum of first 10 terms of an Arithmetic Progression is 55 and the sum of first 9 terms of the same arithmetic progression is 45. Then its 10 term is

Answer»

Answer:

10

Step-by-step explanation:

For first 10 terms:

⇒ 1st term + 2nd term + 3rd term + ... 10TH term

⇒ sum of first 9 term + 10th term

Given, S₉ = 45, S₁₀ = 55

⇒ S₁₀ = S₉ + T₁₀

⇒ 55 = 45 = T₁₀

⇒ 10 = T₁₀

Hence the 10th term is 10

Technique 2:

S₁₀ = (10/2)[2a + 9d] = 10a + 45d = 55

S₉ = (9/2)[2a + 8d] = 9A + 36D = 45

SOLVING these equations, we get

a = 1, and d = 1

Hence 10th term = a + 9d

= 1 + 9(1) = 10

Answer:

Step by step EXPLANATION

x + y = 20

x - y = 10

Adding both the equations above

2x = 30

x = 15

Putting the value of x in x + y = 20, we get

x + y = 20

15 + y = 20
