First term is a and common difference is d.
Sum of first and third terms is 10.
t₁ + t₅ = 10
==> a + (1 - 1) * d + a + (5 - 1) * d = 10
==> a + a + 4d = 10
==> 2a + 4d = 10
==> a + 2d = 5 ---- (1)
Ten Terms except for the first term is 99 and except for sixth term is 89.
S₁₀ - First term = 99
==> 10/2[2a + (10 - 1) * d] - a = 99
==> 5[2a + 9d] - a = 99
==> 10a + 45d - a = 99
==> 9a + 45d = 99
==> a + 5d = 11 ------- (2)
Subtract Equation (1) and (2).
a + 5d - a - 2d = 11 - 5
==> 3d = 6
==> d = 2
Place d = 2 in (2).
==> a + 5d = 11
==> a + 10 = 11
==> a = 1
Third term of the progression.
t₃ = 1 + (3 - 1) * 2
t₃ = 5

=> x² + 9x + 18
=> x² + 6x + 3x +18
=> x ( x+6 ) + 3 ( x+6 )
=> ( x+6 ) ( x+3 )
Therefore, ( x+6 ) ( x+3 ) are the factors .

(b-c)x²+(c-a)x+(a-b)=0
Comparing with quadratic equation
Ax²+Bx+C=0
A=(b-c),
B=c-a,
C=a-b
Discriminate when roots are equal
D=B²-4AC=0
D=(c-a)²−4(b-c)(a-b)=0
D=(c²+a²−2ac)-4(ba-ac-b²+bc)=0
D=c²+a²−2ac-4ab+4ac+4b²-4bc=0
c²+a²+2ac-4b(a+c)+4b²=0
(a+c)²-4b(a+c)+4b²=0
[(a+c)-2b]²=0
a+c=2b

HERE HEIGHT IS 12M
BASE IS 5M
HYPOTNUSE IS LENGTH OF LADDER
BY PYTHAGOROUS THEORUM
HYPOTNUSE^2 = BASE^2 + HEIGHT^2
HYPOTNUSE^2 = 5^2 + 12^2
HYP^2 = 25+144
HYP^2 = 169
HYP = UNDER ROOT OF 169
HYPOTNUSE = 13 M
THEREFORE LENGTH OF LADDER IS 13 M

Question : Factorise 2x^2 - x + 1/8 =0 using splitting the middle term.
Answer :
Given Quadratic equation:
2x²-x+1/8 = 0
Multiply each term by 8 we get
=> 16x² - 8x + 1 = 0
Splitting the middle term,we get
=> 16x² - 4x - 4x + 1 = 0
=> 4x(4x-1)-1(4x-1)=0
=> (4x-1)(4x-1)=0
=> 4x-1=0 or 4x-1 = 0
=> 4x = 1 or 4x = 1
=> x = 1/4 or x = 1/4
Therefore,
Roots of the quadratic equation are 1/4 , 1/4

Answer:
Step-by-step explanation:
Given that if one zero of quadratic polynomial is negative of the other.
we have to find the value of k
Let one zero of above polynomial is α
As one zero is negative of other zero
⇒ sum of zeroes=α+β=α+(-α)=α-α=0

Given : x = √6 + √6 + √6 +... ---(i)
Then,
x = √6 + x --- From Eqn. (i)
On squaring both sides,
⇒ x² = 6 + x
⇒ x² - x - 6 = 0
⇒ x² - 3x + 2x - 6 = 0
⇒ x(x-3) + 2(x-3) = 0
⇒ x = 3 Or x = -2
But x is a natural number.
∴ x = 3

Assume that the length of all edges of the cube=x units
Formula for volume of cube=x³ cube unit
Due an occurrence that the cylinder is within the cube &it touches all the vertices faces of the cube.
Therefore radius of the base of the cylinder & cone & height of cylinder of a cone=x
Volume of the cylinder=π×{x/2}²×x=22/7×x³/4
11/14x³ cube unit
Volume of cone should be=1/3π{x/2)²×x=11/42 cubic unit
Required ratio=volume of cube:volume of cylinder:volume of cone
=x³:11/14x³:11/42x³=42:33:11
