Answer»

Answer:

Step-by-step EXPLANATION:

cos(90°-A) SIN(90°-A)/ tan(90°-A)=1-cos²A

LHS=cos(90°-A) sin(90°-A)/ tan(90°-A)

=SINACOSA /CotA

=sinAcosA /cosA/sinA

=sinA / (1/sinA)

=sin²A

=(sin²A+cos²A)-cos²A

=1-cos²A= RHS

Arun divided Rs 90,000 among his three sons in the ratio 2:3:4. Find the amount received by each son.

Answer»

Step-by-step explanation:

let Arun's three SONS receive the amount as 2X, 3X and 4x respectively.

given: total amount= 90,000

therefore, 2x+3x+4x= 90,000

9x= 90,000

x= 90,000÷9

x= 10,000

hence, first son will get= 2x

= 2×10,000

= 20,000

second son will get= 3x

= 3×10,000

= 30,000

third son will get= 4x

=4×10,000

=40,000

write the length of three sides of a triangle in such a ratio that by which a right angled triangle can be drawn with figure. ​

Answer»

Answer:

A right triangle (American ENGLISH) or right-angled triangle (British English) is a triangle in which one ANGLE is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.

The SIDE opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (or catheti, singular: CATHETUS). Side a may be identified as the side adjacent to angle B and opposed to (or opposite) angle A, while side b is the side adjacent to angle A and opposed to angle B.

If the lengths of all three sides of a right triangle are integers, the triangle is SAID to be a Pythagorean triangle and its side lengths are collectively known as a Pythagorean triple.

The denominator of a rational no. is 4 more than the numerator. If the numerator and the denominator are increased by 1 each the rational no. become 1/2. Find the number.​

Answer»

let numerator be= X

and DENOMINATOR be=x+4

According to the question÷

x+1/x+4+1 =1/2

=> 2(x+1) =1(x+5)

2x+2 = x+5

2x-x =5-2

x = 3

Thus NUMBER is 3/3+4=3/7

To check÷

3+1/7+1= 4/8 =1/2

X squar minus 40x minus 5​

Answer»

Answer:

Step-by-step explanation:

2x + 5x5 - 40X = 2x - 5x5

2x + 25 - 40x = 2x - 25

25 - 40x - 2x = 2x - 25

25 - x(40-2)= 2x - 25

25 - 38X = 2x - 25

= 2x + 38x - 25 -25

=x(2 + 38) -0

=40x

How many terms are there in the sequence of 3/4,1,5/4,...............3?​

Answer»

Answer :

10 terms

Step-by-step explanation :

\underline{\bf Arithmetic \ Progression:}

  • It is the sequence of numbers such that the difference between any two successive numbers is constant.
  • General form of AP,

      a , a+d , a+2d , a+3d , ..........

____________________________

Given series is of A.P, (since the difference between successive terms is constant)

3/4 , 1 , 5/4 , ........ , 3

  • first term,

      a = 3/4

  • common difference,

     d = 1 - 3/4 = 5/4 - 1 = 1/4

Let the nth term be 3 (since it is the LAST term)

   aₙ = 3

we have to find the VALUE of "n"

we KNOW,

 nth term of A.P. is given by,

  \boxed{\bf a_n=a+(n-1)d}

  3=\frac{3}{4} +(n-1)(\frac{1}{4}) \\\\ 3-\frac{3}{4} =(n-1)(\frac{1}{4}) \\\\ \frac{3 \times 4}{4} -\frac{3}{4} =(n-1)(\frac{1}{4}) \\\\ \frac{12}{4} -\frac{3}{4} = (n-1)(\frac{1}{4}) \\\\ \frac{12-3}{4} =(n-1)(\frac{1}{4}) \\\\ \frac{9}{4}=(n-1)(\frac{1}{4}) \\\\ 9=(n-1)(1) \\\\ n-1=9 \\\\ n=9+1 \\\\ n = 9+1 \\\\ \bf n=10

There are 10 terms in the given sequence of A.P.

Solve no 4 quadratic equation​

Answer»

Answer :

\bf x= \frac{3+\sqrt{29}}{2} , \frac{3-\sqrt{29}}{2}

Step-by-step explanation :

Quadratic POLYNOMIALS :

✯ It is a polynomial of degree 2

✯ General form :

       ax² + bx + c  = 0

✯ Determinant, D = b² - 4ac

✯ Based on the VALUE of Determinant, we can DEFINE the nature of roots.

     D > 0 ; real and unequal roots

     D = 0 ; real and equal roots

     D < 0 ; no real roots i.e., imaginary

RELATIONSHIP between zeroes and coefficients :

      ✩ Sum of zeroes = -b/a

      ✩ Product of zeroes = c/a

________________________________

Given quadratic equation,

 x² = 3x + 5

x² - 3x - 5 = 0

It is of the form ax² + bx + c = 0

a = 1 , b = -3 , c = -5

By using quadratic formula,

 \boxed{\bf x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} }

Substitute the values,

  x=\frac{-(-3) \pm \sqrt{(-3)^2-4(1)(-5)} }{2(1)} \\\\ x=\frac{3 \pm \sqrt{9+20} }{2} \\\\ x=\frac{3 \pm \sqrt{29} }{2} \\\\\\ \bf \implies x= \frac{3+\sqrt{29}}{2} , \frac{3-\sqrt{29}}{2}
