We know that, if a matrix is of order m x n, it has mn elements, where m and n are natural numbers.We have, m x n = 28⇒ (m, n)= {(1, 28), (2, 14), (4, 7), (7, 4), (14, 2), (28, 1 )}So, the possible orders are I x 28, 2 x 14, 4 x 7, 7 x 4, 14 x 2, 28 x 1.Also, if it has 13 elements,then m x n = 13⇒ (m, n)= ((1, 13), (13, l)}Hence, the possible orders are 1 x 13, 13 x 1.

Solution:-Volume of sphere = 4/3πr³= 4/3*22/7*10.5*10.5*10.5Volume of metallic sphere = 4851 cm³Now,Volume of one cone = 1/3πr²h= 1/3*22/7*3.5*3.5*3Volume of one cone = 38.5 cm³Total number of cones = Volume of metallic sphere/volume of one cone= 4851/38.5= 126 conesTotal number of cones can be formed is 126

sin^2 A-sin^4A= cos^2A-cos ^4Asin^2A(1-sin^2A) = cos^2A(1-cos^2A)

cos^2A= cos^2A

ab+bc+ca=47hence2*(ab+bc+ca)=2*47=94hence(a+b+c)^2=a^2+b^2+c^2+2(ab+bc+ca)hence(a+b+c)^2=50+94=144hencea+b+c=12

sin^2 63 + sin^2 27/cos^2 17 + cos^2 73

(using cos (90 - x) = sinx sin(90 - x) = cosx sin^2 x + cos^2 x = 1)

= sin^2 63 + cos^2 (90 - 27)/ sin^2 (90 - 17) + cos^2 73

= sin^2 63 + cos^2 63/ sin^2 73 + cos^2 73

= 1

If you find this answer helpful then like it.

Given f(x) = 5x^3 - 13x^2 + 21x - 14.

Given g(x) = 3 - 2x + x^2.

We need to divide f(x) by g(x).

5x - 3 ---------------------------------= > x^2 - 2x + 3) 5x^3 - 13x^2 + 21x - 14

5x^3 - 10x^2 + 15x

---------------------------------

-3x^2 + 6x - 14

- 3x^2 + 6x - 9

-----------------------------------

-5.

Here,

Dividend = 5x^3 - 13x^2 + 21x - 14

Divisor = 3 - 2x + x^2

Quotient = 5x - 3

Remainder = -5

Division Algorithm:

Dividend = Divisor * Quotient + Remainder

= (3 - 2x + x^2) * (5x - 3) + (-5)

= 15x - 9 - 10x^2 + 6x + 5x^3 - 3x^2 - 5

= 5x^3 - 13x^2 + 21x - 14.

LHS = RHS

Given:

x = 7 + √40 = 5 + 2 + 2√10 = (√5 + √2)²

√x = √5 + √2

1/√x = 1/(√5 + √2) = (√5 - √2)/((√5 + √2)(√5 - √2) = (√5 - √2)/(5 - 2) = (√5 - √2)/3

√x + 1/√x = √5 + √2 + (√5 - √2)/3 = (2/3)(2√5 + √2)

When the number of columns of the 1st matrix must equal the number of rows of the 2nd matrix. In other words, To multiply an m×n matrix by an n×p matrix, the n's must be the same, and the result is an m×p matrix.

Directive property of multiplication is the property I think

this question is wrong

a, b, c are Pythagorean triplet then

a² + b² = c²

So, 3² + 4² = 5²

B) is correct option

R

your sister gave you six five rupee notes to buy something in the market .how much money did you get from your sister?

answer is third 2 2 2

a-b = 7ab = 9we have(a-b)² = a² + b² - 2ab7² + 28 = a² + b²a² + b² = 49 + 28 = 77

let a,b,c be the three numbers. According to question,a+b+c=10a²+b³+c³=160

10-{8+(4÷2)}=10-{8+2}=10-10=0.

23) Sum of each row is 3 times the middle number.4+3+2=9=3*35+3+5+1+1=15=3*56+1+2+8+3+3+1=24=3*87+2+8+4+3=24=3*8So,9+x+3=3xx=6(B)6 is the correct answer.

24) Each number is multiplied with increasing multiples of 2.7+2^0=88+2^1=1010+2^2=14..........262+2^8=518(B)518 is the correct answer.
