Answer» Answer: the answer is that it DEPENDS on the domain. in the INTEGERS, RATIONAL numbers and real numbers, the answer is no. However, in the COMPLEX numbers, where there is a solution to x^2+1=0, you can factor into (x-i)(x+i), where i^2=-1 (this number is no more imaginary than π).

Comment about following pair of equation:- 2x + 3y = 5 6x + 9y = 6

Answer»

Answer:

$\bold {According \: to \: Question}$

2x + 3y = 5.....(1)

6X +9y = 6......(2)

2x + 3y -5 = 0......(3)

6x + 9y -6 = 0......(4)

Comparing with $\frac {a1}{a2}$ ; $\frac {b1}{b2}$ ; $\frac {c1}{c2}$ , we GET:-

$\frac {2}{6}$ ; $\frac {3}{9}$ ; $\frac {-5}{-6}$

$\frac {1}{3}$ = $\frac {1}{3}$ =\= $\frac {5}{6}$

Therefore, The answer is Parallel lines with no solution.

$\tt {Additional \: Information}$

• If a pair of equations are $\frac {a1}{a2}$ is not equal to $\frac {b1}{b2}$ then the pair of equations are interesting lines with UNIQUE solution.

• If a pair of equations are $\frac {a1}{a2}$ is equal to $\frac {b1}{b2}$ is equal to $\frac {c1}{c2}$ , then the pair of equations are coincident lines with infinitity many solution.

• If a pair of equations are $\frac {a1}{a2}$ is equal to $\frac {b1}{b2}$ is not equal to $\frac {c1}{c2}$ , then the pair of equations are parallel lines with no solution.

7.	If cos (A + B) = 0, then sin (A - B) can be reduced to
Answer» => cos (A + B) = 0 => cos (A + B) = cos 90° => (A + B) = 90 => A = 90 - B = sin (A - B) = sin (90 - B - B) = sin (90 - 2B) = cos 2B

7.

If cos (A + B) = 0, then sin (A - B) can be reduced to

Answer»

=> cos (A + B) = 0

=> cos (A + B) = cos 90°

=> (A + B) = 90

=> A = 90 - B

= sin (A - B)

= sin (90 - B - B)

= sin (90 - 2B)

= cos 2B

If 6 sin²θ + 2 cos²θ=7 sinθcosθ then find the value of tan θ. Class 10

Answer»

$\textbf{Given:}$

$6\,sin^2\theta+2\,cos^2\theta=7\,sin\theta\,cos\theta$

$\textbf{To find:}$

$\text{The value of}\;\tan\theta$

$\textbf{Solution:}$

$\text{Consider,}$

$6\,sin^2\theta+2\,cos^2\theta=7\,sin\theta\,cos\theta$

$\text{Divide bothsides by $\sin\theta\,\cos\theta$}$

$\dfrac{6\,sin^2\theta}{sin\theta\,cos\theta}+\dfrac{2\,cos^2\theta}{sin\theta\,cos\theta}=7$

$\dfrac{6\,sin\theta}{\cos\theta}+\dfrac{2\,cos\theta}{sin\theta}=7$

$6\,tan\theta+2\,cot\theta=7$

$6\,tan\theta+2(\dfrac{1}{tan\theta})=7$

$6\,tan^2\theta+2=7\,tan\theta$

$6\,tan^2\theta+7\,tan\theta+2=0$

$6\,tan^2\theta+4\,tan\theta+3\,tan\theta+2=0$

$2\,tan\theta(3\,tan\theta+2)+1(3\,tan\theta+2)=0$

$(2\,tan\theta+1)(3\,tan\theta+2)=0$

$\implies\,tan\theta=\dfrac{-1}{2},\dfrac{-2}{3}$

Answer» Answer: 5 tan theta=4 So tan theta=4/5 therefore, SIN theta/cos theta = 4/5 Hence we can say that, sin theta= 4x , cos theta= 5x So, (5 sin theta - 3 cos theta)/(5 sin theta+ 2 cos theta) = (20x-15x)/(20x+10x) = 5x/30x=1/6 Step-by-step explanation: GIVEN that , 5 tan theta = 4 tan theta = 4/5 We know that tan theta = Sin theta/Cot theta Say X Sin theta = 4x Cos theta = 5x Evaluate the values of LHS Side \frac{5 \ Sin\theta - 3\ Cos\theta}{5\ Sin\theta + \ 2Cos\theta} => \frac{(5 * 4 )- (3 * 5) }{(5 * 4) + (2 * 5)} => \frac{20 -15}{20+ 10} => \frac{5}{30} => \frac{1}{6} hope you find it easy plz mark me as brainliest.....

35.

If 5tan theta = 4,find the value of 5sin theta - 3 cos theta /5sin theta +2 cos theta.

Answer»

Answer:

5 tan theta=4

So tan theta=4/5

therefore, SIN theta/cos theta = 4/5

Hence we can say that,

sin theta= 4x , cos theta= 5x

So, (5 sin theta - 3 cos theta)/(5 sin theta+ 2 cos theta)

= (20x-15x)/(20x+10x)

= 5x/30x=1/6

Step-by-step explanation:

GIVEN that ,

5 tan theta = 4

tan theta = 4/5

We know that

tan theta = Sin theta/Cot theta

Say X

Sin theta = 4x

Cos theta = 5x

Evaluate the values of LHS Side

\frac{5 \ Sin\theta - 3\ Cos\theta}{5\ Sin\theta + \ 2Cos\theta}

=> \frac{(5 * 4 )- (3 * 5) }{(5 * 4) + (2 * 5)}

=> \frac{20 -15}{20+ 10}

=> \frac{5}{30}

=> \frac{1}{6}

Find the number of terms in the AP 17, 29/2, 12,..., -38

Answer»

ANSWER:

GIVEN that,

a=17

common DIFFERENCE = a2-a1

=29/2-17

=29/2-34/2

= -5/2

an= -38

therefore, by the FORMULA,

an=a+(n-1)d

-38=17+(n-1) (-5/2)

-38=17-5/2+(n-1)

-38=34-5/2+(n-1)

-38=29/2+(n-1)

-38×2=29+(n-1)

-76=29+(n-1)

-76-29=(n-1)

-105=(n-1)

-105+1=n

-104=n
