Hola User______________

Here is your Answer...!!

______________________

The time relation equation will be ...

1) t = 64 (0.5)^r

since it can be proved , by placing values of r

thus as

1) r=0 ; t = 64
2) r=1 ; t = 32
3) r=3 ; t = 16

and so on...

Answer:

Number 1 would be the answer.

Step-by-step explanation:

if we use round 3 as an example, then 64(0.5)^3 would equal 8, which is the number of teams remaining.

Prove: If n is a positiveinteger and n2 is divisible by 3, then n is divisible by3.

Answer:

If $n^2$ is divisible by 3, the n is also divisible by 3.

Step-by-step explanation:

We will prove this with the help of contrapositive that is we prove that if n is not divisible by 3, then, $n^2$ is not divisible by 3.

Let n not be divisible by 3. Then $\frac{n}{3}$ can be written in the form of fraction $\frac{x}{y}$ , where x and y are co-prime to each other or in other words the fraction is in lowest form.

Now, squaring

$\frac{n^2}{9} = \frac{x^2}{y^2}$

Thus,

$n^2 = \frac{9x^2}{y^2}$

$\frac{n^2}{3} = \frac{3x^2}{y^2}$

It can be clearly seen that the fraction $\frac{3x^2}{y^2}$ is in lowest form.

Hence, $n^2$ is not divisible by 3.

Thus, by contrapositivity if $n^2$ is divisible by 3, the n is also divisible by 3.
