Factor of 15(X2 +2xy)​

Answer»

ong>Answer:

Step-by-step explanation:   Start by factoring  15x2+2xy−24y2  and then HOPE for the best. FACTOR this by decomposition or by magic.

Note that  15×24=360 . So we seek two NUMBERS with product being  360  and difference  2  with the larger assigned a positive sign. The numbers are  20  and  18 . So continue in the following way:

15x2+2xy−24y2=15x2+20xy−18xy−24y2=5x(3x+4y)−6y(3x+4y)=(5x−6y)((3x+4y).  

Now for the hoping part. The  −6  could mess the whole THING up. In fact, had it been some other number, the quadratic would not factor. Here’s what we do. SET  y=0  and factor the result. The factored form is  (5x+3)(3x−2)  with the important numbers being  3  and  −2 . This suggests that

15x2+2xy−24y2−x+24y−6=(5x−6y+3)(3x+4y−2) .

LET the two quantities to be MIXED be x and y, respectively.

Then we have, x * 72 + y * 90 = (x + y ) * 78

72x + 90y = 78x + 78y

6x = 12y

Hence , ratio x/y = 2/1

Hence the two varieties are to be ADDED in the ratio , 2:1

Answer» ONG>Answer:

your answer

Step-by-step explanation:

Mean =SUM of observation/ no. of observations

=2+3+4+5+0+1+3+3+4+3/10

=28/10

=2.8

mean = 2.8

median

let us write GIVEN observatins in ascending order

= 0123333445

here no. of observations r 10 which is an even no.

therefore observation at 5th and 6TH place is at middle position ile. 3 and 3

median = sum of observation at 5th and 6th place / 2

= 3+3/2

=6/2

=3

median = 3

mode= observation which repeated maximum time

= 3

mode = 3

Sin theta + cos theta is equal to cosec theta prove LHS and RHS equal​

Answer»

ong>ANSWER:

We have to prove that

cot+cosecθ

sinθ

​  

=2+  

cotθ−cosecθ

sinθ

​  

or,  

cotθ+cosecθ

sinθ

​  

−  

cotθ−cosecθ

sinθ

​  

=2

Now,

⇒ LHS =  

cotθ+cosecθ

sinθ

​  

−  

cotθ−cosecθ

sinθ

​  

 

⇒ LHS =  

cosecθ+cotθ

sinθ

​  

+  

cosecθ−cotθ

sinθ

​  

 

⇒ LHS = sinθ{  

cosecθ+cotθ

1

​  

+  

cosecθ−cotθ

​  

}

⇒ LHS = $$sin \, \theta\left\{\dfrac{cosec \, \theta \, - \, cot \, \theta \, + \, cosec \, \theta \, + \, cot \, \theta}{cosec^2 \, \theta \, - \, cot^ \, \theta}\right\} \, = \, sin \, \theta \, \left(\dfrac{2 \, cosec \, \theta}{1} \right)$$

⇒ LHS = sinθ(2cosecθ)=2sinθ×  

sinθ

1

​  

=2=RHS

⇒ LHS = 2 = RHS

ALTERNANATIVELY,

LHS =  

cotθ+cosecθ

sinθ

​  

 

⇒LHS=sinθ(cosecθ−cotθ)      [∵  

cosecθ+cotθ

​  

=cosecθ−cotθ]

⇒ LHS = sinθ(  

sinθ

1

​  

−  

sinθ

cosθ

​  

)=sinθ(  

sinθ

1−cosθ

​  

)

⇒ LHS = 1 - COS θ

⇒ = 2 - (1 + cos θ)

⇒ LHS = 2 -  

1−cosθ

(1+cosθ)(1−cosθ)

​  

 

⇒ LHS = 2 -
