Answer:

No, it is <em>not</em> a right triangle.

Step-by-step explanation:

We know that there are <em>2 legs </em>and <em>1 hypotenuse</em>. The <em>hypotenuse is 76</em> because it is the<em> largest number</em>. And the two <em>legs are 73 and 26</em>. Now to find if it is a right triangle we will take <em>73 and multiply it by itself</em>, which is <em>5,329</em>. Now we will do the same with 26 and we get <em>676.</em> Then we <em>add 676 to 5,329</em> and we get <em>6,005</em>. Because we are trying to find the hypotenuse, we have to find what number <em>when squared</em> makes<em> 6,005</em>. Since <em>76 x 76 = 5,776</em> it is<em> not a right triangle. </em>

Here is an image of the triangle:

Show that 3 · 4^n + 51 is divisible by 3 and 9 for all positive integers n.

-BARSIC- [3]

Answer:

Step-by-step explanation:

Hello, please consider the following.

$3\cdot 4^n+51=3\cdot 4^n+3\cdot 17=3(4^n+17)$

So this is divisible by 3.

Now, to prove that this is divisible by 9 = 3*3 we need to prove that

$4^n+17$ is divisible by 3. We will prove it by induction.

Step 1 - for n = 1

4+17=21= 3*7 this is true

Step 2 - we assume this is true for k so $4^k+17$ is divisible by 3

and we check what happens for k+1

$4^{k+1}+17=4\cdot 4^k+17=3\cdot 4^k + 4^k+17$

$3\cdot 4^k$ is divisible by 3 and

$4^k+17$ is divisible by 3, by induction hypothesis

So, the sum is divisible by 3.

Step 3 - Conclusion

We just prove that $4^n+17$ is divisible by 3 for all positive integers n.
