Bet u can’t solve this

Answer:

Step-by-step explanation:

Assuming you're solving for p:

$m=2^{-1} *2^p(2^p-1)$

Let $y=2^p$

Now we can re-write the equation with $y$ instead of $2^p$ .

$m=\frac{1}{2} y(y-1)$

$2m=y^2-y$

$y^2-y-2m=0$

Use the quadratic formula to get:

$y = \frac{1+\sqrt{1+8m} }{2}$

or

$y = \frac{1-\sqrt{1+8m} }{2}$

Therefore, using natural log and log rules:

$2^p = \frac{1+\sqrt{1+8m} }{2}$ , $ln(2^p)= ln(\frac{1+\sqrt{1+8m} }{2})$ , $pln(2) = ln(\frac{1+\sqrt{1+8m} }{2})$ , $p = \frac{ln(\frac{1+\sqrt{1+8m} }{2})}{ln(2)}$

or

$2^p = \frac{1-\sqrt{1+8m} }{2}$ , $ln(2^p)= ln(\frac{1-\sqrt{1+8m} }{2})$ , $pln(2) = ln(\frac{1-\sqrt{1+8m} }{2})$ , $p = \frac{ln(\frac{1-\sqrt{1+8m} }{2})}{ln(2)}$

If I haven't made any mistakes this should be correct!

How do you determine if a set of numbers form a Pythagorean triple?

Sladkaya [172]

Answer:

The 3 numbers must be multiples of 3, 4, and 5

Step-by-step explanation:

Pythagorean Triples are numbers that you know will come out perfectly in the Pythagorean Theorem. But the easiest way to explain this is to show you an example.

Say you're given the numbers 12, 16, and 20.

They should be able to be divided by the same number and equal 3, 4, and 5.

In this case, the number is 4.

12/4=3

16/4=4

20/4=5

So, this is a 3-4-5 triangle, or a Pythagorean Triple.
