So as to have the function be increasing, 2016-m2 must be positive. Therefore, 2016 must be greater than m2. Since 2016 is a positive number, m has to range from \(-\sqrt{2016}\) to \(\sqrt{2016}\). In other words, m has to be between -44.899 and 44.899. Since m is a whole number, the minimal value of m is -44 and the maximum is 44. To calculate the number of values, we use this formula:
\(N=\frac{44-(-44)}{1}+1=89\)To conclude, there are 89 values of m such that the function is increasing.

The sum of the three numbers is 120.
The sum of the two remaining numbers is 101.
The lowest possible value for the second number is 20.
So the highest number would be 81. -

Analyzing the numbers first, we can see that each number increases by 1, 2, 3, 4, 5 ... progressively arithmetically increasing.
So the number that comes next is definitely 22
Analyzing the letters, it will be the order of the letter in the Latin alphabet.
So the letter is V
So it's V22 -

Mininum divisors? That is the number 1, obviously
Or did you mean the minimum NUMBER of divisors?
If so than it's 9, how you ask?
To create less permutations with the divisors, the factors should overlap the most, hence, the 6 divisor number is a5 and the 4 divisor number is a3, so the product would be a8, having 9 divisors. -

\(x+4567108=\left(-4566109\right)\)
\(x=\left(-4566109\right)-4567108=-9133217\)
\(x\times\left(-8\right)=\left(-9133217\right)\times\left(-8\right)=73065736\)
I have no idea how one is supposed to do this without a calculator -

We have the domain of f(x), time to replace all of these values into the variables...
After a while of repetition, we will get the range of f(x) is {-3;-2;1;6;13}
So the intersection of these two sets is {-3;-2;1} -

Simplifying? Okay
\(\dfrac{2}{x-1}+\dfrac{2x-1}{x^2+x+1}-\dfrac{x^2+6x+2}{1-x}=\dfrac{2}{x-1}+\dfrac{2x-1}{x^2+x+1}+\dfrac{x^2+6x+2}{x-1}\)Condition for x: \(x\ne1\)
\(\dfrac{2\left(x^2+x+1\right)}{x^3-1}+\dfrac{\left(2x-1\right)\left(x-1\right)}{x^3-1}+\dfrac{\left(x^2+6x+2\right)\left(x-1\right)}{x^3-1}\)
\(\Rightarrow2x^2+2x+2+2x^2-2x-x+1+x^3+6x^2+2x-x^2-6x-2\)
\(=x^3+3x^2-5x+1\)

After each round, the number of people will divide by half.
So 32 => 16 => 8 => 4 => 2 => Champion
The number of matches each round will be determined by the value of HALF the number of participants:
So there will be 16+8+4+2+1=31(matches) -
