4.	QUESTION_________________________________Derive the formula for finding the number of diagonals in polygon. ____________________________ Harsh Pratap Singh
Answer» $\huge\underline\red{ANSWER}$ We can simply derive using the FOLLOWING MEATHOD:- For each vertex N(VERTICES) you have (n−3) possible vertices to create a diagonal from. Why (n−3)? Because you can't combine with the 2 neighboring vertices and you can't combine with your current vertex. Divide by two because you are counting twice. So you have (n−3)n/2 diagonals.

Answer» ANSWER: Step-by-step explanation: in question given diameter = 40 cm radius = D/2 = 40/2 = 20cm. the LENGTH of a chord is 20cm. a/q ∆ OAB is EQUILATERAL traingle. θ = 60° l = 20 × 60° × π / 180° l = 20π / 3cm thus, the length of the minor arc of the chord 20π / 3cm

10.

in in a circle of diameter 40 cm the length of a chord is 20 cm find the length of minor arc of the chord. please answer in deatail

Answer»

ANSWER:

Step-by-step explanation:

in question given

diameter = 40 cm

radius = D/2

= 40/2

Answer» Your answer is given-::: a² + b² + c² = (a+b+c)² - 2(ab + bc + ca) The actual formula is (a+b+c)² = a² + b² + c² +2( ab + bc + ca) You can GET this simple formula by multiplying (a+b +c) with (a+b+c). (a+b +c)² = (a+b +c)(a+b +c) = a(a+b +c) + b(a+b +c) + c(a+b +c) = a² + ab + ac + ab + b² + bc + ca + bc + c² = a² + b² + c² + 2ab + 2bc + 2CA = a² + b² + c² + 2( ab + bc + ca) I HOPE you get the formula and found it simple.

11.

Which equationSquare = is A square + B Square = C Square And who made it

Answer»

Your answer is given-:::

a² + b² + c² = (a+b+c)² - 2(ab + bc + ca)

The actual formula is

(a+b+c)² = a² + b² + c² +2( ab + bc + ca)

You can GET this simple formula by multiplying (a+b +c) with (a+b+c).

(a+b +c)² = (a+b +c)*(a+b +c)

= a*(a+b +c) + b*(a+b +c) + c*(a+b +c)

= a² + ab + ac + ab + b² + bc + ca + bc + c²

= a² + b² + c² + 2ab + 2bc + 2CA

= a² + b² + c² + 2( ab + bc + ca)

20.

Find the nth derivative of 1/(x2+6x+8)

Answer»

Given:

y = 1 / (x²+6x+8)

To find:

The NTH derivative

Calculation:

=> y = 1 / (x²+6x+8)

y = 1 / (x+2)(x+4)

y = 2[ 1/(x+2) - 1/(x+4) ]

DERIVATE both SIDES of the equation w.r.t x

=> y₁ = dy/dx = 2[ -1/(x+2)² + 1/(x+4)² ]

= -2[ 1/(x+2)² - 1/(x+4)² ]

Derivate both sides of the equation w.r.t x

=> y₂ = d²y/dx² = -2[ -2/(x+2)³ + 2/(x+4)³ ]

= 4[ 1/(x+2)³ - 1/(x+4)³ ]

Derivate both sides of the equation w.r.t x

=>y₃ = d³y/dx³ = 4[ -3/(x+2)⁴ + 3/(x+4)⁴ ]

= -12[ 1/(x+2)⁴ - 1/(x+4)⁴ ]

y_(n) = 2(-1)ⁿn![ 1/(x+2)ⁿ⁺¹ - 1/(x+4)ⁿ⁺¹ ]

Final answer:

The nth derivative is y_(n) = 2(-1)ⁿn![ 1/(x+2)ⁿ⁺¹ - 1/(x+4)ⁿ⁺¹ ]

Answer»

Step-by-step EXPLANATION:

x-3y+5=4

x-3y+1=0

-3y+x+1=0

-3y=-x-1

m=-1/3

mm==-1

m(-1/3)=-1

m=3

(y+2)=3(x-3)

y+2=3x-9

y+2-3x+9=0

Answer»

Answer:

If her marks in Math is 12, then in English she got 18.

If MATHS mark is 13, then she got 17 in English.

Step-by-step explanation:

Let the marks in Math be x and in English (30−x).

New marks in Math =2+x

New marks in English =27−x

(2+x)(27−x)=210

54−2x+27x−x^2 =210

x^2−25x+156=0

x^2−12x−13x+156=0

x(x−12)−13(x−12)=0

(x−12)(x−13)=0

x=12,13

If her marks in Math is 12, then in English she got 18.

If maths mark is 13, then she got 17 in English.
