1. Always true. 1+1=2
2. Always true. 1+e is irrational.
3. Sometimes true. e + (-e) = 0 which is rational.
4. Always true. 1*1 = 1
5. Sometimes true. 0*e = 0 which is rational.
6. Sometimes true. Sqrt(2) * sqrt(2) = 2 which is rational.

The question asked for an example to support your answer, but none of the answers can be proven with just one example. The answers which are sometimes true need 2 examples to be proven, and the answers which are always true cannot be proven by example.

BabaBlast [244]

Answer:

equation: a/.5b=h

h=9

Step-by-step explanation:

a=1/2bh

divide both sides by 1/2b to get h alone

a/.5b=h

a/.5b=h

54/0.5(12)=h

54/6=h

9=h

which expression is equivalent to 100 n2 − 1? (10n)2 − (1)2 (10n2)2 − (1)2 (50n)2 − (1)2 (50n2)2 − (1)2

Which expression is equivalent to 100 n2 − 1? (10n)2 − (1)2 (10n2)2 − (1)2 (50n)2 − (1)2 (50n2)2 − (1)2

Regroup:
100n^2-1

=10^2n^2-1
=(10n)^2-1^2

So the correct answer is : 
(10n)^2-1^2

To attempt to factor a polynomial of four or more terms with no common factor, first rewrite it in groups. Each group may possibly be separately factored, and the resulting expression may possibly lend itself to further factorization if a greatest common factor<span> or special form is created.</span>

lisabon 2012 [21]

Answer:

After 16 rounds the champion of Ping-Pong player can be determined.

Step-by-step explanation:

This is an example of geometric progression,

First term = 65,536

\texttt{Common ratio = }\frac{1}{2}

Now we need to find which term is 1 in this GP.

N th term of GP is given by

             t_n=ar^{n-1}

Substituting

               1=65536\times \left ( \frac{1}{2}\right )^{n-1}\\\\\frac{1}{65536}=\left ( \frac{1}{2}\right )^{n-1}\\\\2^{n-1}=65536\\\\2^{n-1}=2^{16}\\\\n=17

Seventeenth term of this GP is 1.

That is after 16 rounds the champion of Ping-Pong player can be determined.
