he remainder is 2.
Step-by-step explanation:
Since we gave given that
when k is divided by 21, it gives a remainder of 9
So, when the same number k is divided by 7, we need to find the remainder.
Since 21 is divisible by 7.
and remainder will be 0.
In such a case, we will consider the remainders only.
So, 9÷7, we get 2 as a remainder
because, 9 = 7×1 +2
Hence, the remainder is 2.

Let α and β be the zeros of the polynomial 4x²-8kx-9
It is given that α=-β
Then, α+β=0
-b/a=0
-(coefficient of x)/coefficient of x²=0
8k/4=0
2k=0
k=0

π is defined to be the ratio of the circumference of a circle over its diameter (or 2 times its radius).
This ratio is a constant since all circles are geometrically similar and linear proportions between any similar geometric figures are constant.
If you were looking for how the value of the ratio π is calculated or how we know that the same ratio applies to the area of a circle, then those are different questions. (Ask if either of these are what you were looking for).
