Question

sin2Ꝋ = then the value of cosecꝊ​

Answer 1

Answer:

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion.

Answer 2

Answer:

Correct option is

A

9

As the right hand digit of the sum of A+B+C=C,

it means that A+B=10 so A or B, none can be 0.

Also, the sum of A+B+C can not exceed 19.  

So, 1 is carried to the second column.  

Now, 1+A+B+C gives A as the right digit of the sum.  

So, A=C+1.  

Further, again 1 is carried over to the third column as A

cannot be 0 and the sum of 1+A+B+C can be at most 19.

On adding A+B+C+1 we get BA, thus here B=1.

Using A+B=10,A=10−1=9

Also, A=C+1

⇒C=A−1=9−1=8.

So, A=9,B=1 and C=8 satisfy all the conditions.

So, option A is correct.
