18703.

The value of k for which the system of equation x+3y-4=0 and 2x+ky=7 is inconsistent

Answer»

Answer:

k=6

Step-by-step explanation:

inconsistent means no SOLUTION a1/a2=b1/b2 is not equal to c1/c2

from equation 1 and 2

a1/a2=1/2

b1/b2=3/k

c1/c2= -4/-7 =4/7

$a1/a2=b1/b2\neq c1/c2$

$1/2=3/k\neq 4/7$

if k=6

then 3/6 =1/2

therefore 1/2=1/2 $\neq$ c1/c2

when we substitute k=6 3 and 6 gets CANCELLED where it becomes 1/2 then the formula will be satisfied.

18704.	Evalute sin60°cos30°+sin30°cos60°
Answer» Step-by-step EXPLANATION: Sin 60 = root 3 /2 cos 30 = root 3 /2 sin 30 = 1/2 cos 60 = 1/2 = (root 3 /2 ) (root 3 / 2) + (1/2) (1/2) = 3/4 + 1/4 = 4/4 = 1 sin 60 + 30 = 90 where sin 90 = 1

18704.

Evalute sin60°cos30°+sin30°cos60°

Answer»

Step-by-step EXPLANATION:

Sin 60 = root 3 /2

cos 30 = root 3 /2

sin 30 = 1/2

cos 60 = 1/2

= (root 3 /2 ) (root 3 / 2) + (1/2) (1/2)

= 3/4 + 1/4

= 4/4

= 1

sin 60 + 30 = 90

where sin 90 = 1

18716.

The sum of three consecutive multiples of 7 is 777. Find the multiples.

Answer»

Step-by-step explanation:

let the THREE consecutive MULTIPLES be 7x, 7x+7, 7x+14

the SUM of three consecutive multiple is 777

7x + (7x + 7) + (7x + 14) =777

21x + 21 =777

21x = 777 -21

21x = 756

x = 756/21

x= 36

substitute x

7x= 7 (36)= 252

(7x + 7) = 7(36) + 7 = 259

(7x +14 ) = 7 (36) + 14 = 262

therefore the three multiples are 252, 259, 262

Clear selection2 points38. If x2 + k(4x + k – 1) + 2 = 0 has equal roots, then k =(a)(b) ,-1(c)3 1(d)ilm12 3аObOCOdClear selection

Answer»

ANSWER:

SOLUTION :

Option (b) is correct : ⅔ , - 1

GIVEN : x² + k(4x + k - 1) + 2 = 0

x² + 4kx + k² - k + 2 = 0

On comparing the given EQUATION with ax² + BX + c = 0

Here, a = 1 , b = 4k , c = k² - k + 2

D(discriminant) = b² – 4ac

D = (4k)² - 4 × 1 × (k² - k + 2)

D = 16k² - 4k² + 4k - 8

D = 12k² + 4k - 8

D = 4(3k² + k - 2)

D = 0 (equal roots given)

4(3k² + k - 2) = 0

(3k² + k - 2) = 0

3k² + 3k - 2k - 2 = 0

[By middle term splitting]

3k (k + 1) - 2(k + 1) = 0

(3k - 2)(k + 1) = 0

(3k - 2) = 0 (k + 1) = 0

3k = 2 or k = - 1

k = ⅔ or k = - 1

Hence, the value of k is ⅔ & - 1.

The sum of the numerator and denominator of a fraction is greater by 1 than thrice the numerator. If the numerator is decreased by 1, then the fraction reduced to 1/3. Find the fraction. Solution : The fraction is .........3 points

Answer»

Answer:

The numerator be 'x' and DENOMINATOR be ' y'

then,

the sum of the numerator and denominator of a fraction is 3 less than the twice is x+y=2y-3 :- x-y+3=0 - equation 1

if the numerator and denominator is decreased by 1 then

x-1/y-1=1/2 :- 2(x-1) = 1(y-1) :- 2x-y-1=0 -equation 2

then equation 1 = equation 2

x-y+3=2x-y-1 :- x=4

from the equation 1

x-y+3=0 :- 4-y+3=0 :- y=7

there FORE the fraction is 3/7

Step-by-step EXPLANATION:

$hope it will be helpful to you..✌$

18745.

FIND THE ZEROES OF THE FOLLOWING QUADRATIC EQUATION AND VERIFY THE RELATIONSHIP BETWEEN ZEROES AND THE COEFFICIENTS? 2 MARKS 3X^2-X-4

Answer»

Answer:

answer is,

SUM of zeroes=1/3

product of zeroes=(-4/3)

Step-by-step EXPLANATION:

GIVEN,

=3x^2-x-4

=3x^2-4x+3x-4

=x(3x-4)+1(3x-4)

=(x+1)(3x-4)

=x=4/3,(-1)

therefore alpha and beta Alpha=4/3

beta=(-1)

sum of zeroes=alpha+beta

=4/3-1

=1/3

- b/a=-(COEFFICIENT of x)/(coefficient of x^2)

=-(-1)/3

=1/3

product of zeroes=alpha×beta

=4/3×(-1)

=(-4/3)

c/a=constant/coefficient of x^2

=(-4/3)

Answer» Given : The population of a particular town 4 years back was 2,500. The current population is 4,000. the rate of growth of the population has been kept constant and it has been compounded annually To find : What will be the population after a period of 4 years Solution: LET say rate of growth = r % per annum A = P(1 + r/100)ⁿ as rate of growth of the population has been kept constant and it has been compounded annually Population 4 years back = 2500 Time period n = 4 years Current population = 2500 ( 1 + r/100)⁴ => 4000 = 2500 ( 1 + r/100)⁴ => ( 1 + r/100)⁴ = 1.6 Current population = 4000 Population after 4 years = 4000 ( 1 + r/100)⁴ Substitute ( 1 + r/100)⁴ = 1.6 => Population after 4 years = 4000 * 1.6 => Population after 4 years = 6400 population after a period of 4 years = 6400 Learn more: Q2.

the population of a particular town 4 years back was 2500 current population is 4000. what will be the population after 4 years of rate of growth of population has been kept constant and it has been compounded annually

Answer»

Given : The population of a particular town 4 years back was 2,500. The current population is 4,000. the rate of growth of the population has been kept constant and it has been compounded annually

To find : What will be the population after a period of 4 years

Solution:

LET say rate of growth = r % per annum

A = P(1 + r/100)ⁿ as rate of growth of the population has been kept constant and it has been compounded annually

Population 4 years back = 2500

Time period n = 4 years

Current population = 2500 ( 1 + r/100)⁴

=> 4000 = 2500 ( 1 + r/100)⁴

=> ( 1 + r/100)⁴ = 1.6

Current population = 4000

Population after 4 years = 4000 ( 1 + r/100)⁴

Substitute ( 1 + r/100)⁴ = 1.6

=> Population after 4 years = 4000 * 1.6

=> Population after 4 years = 6400

population after a period of 4 years = 6400
