Answer:
<em>n</em> - <em>k</em> + 1
Step-by-step explanation:
This is assuming (because you did not say) that <em>n</em> and <em>k</em> are integers and <em>n</em> is greater than <em>k</em>.
Example: from 2 to 5 {2, 3, 4, 5} includes 5 - 2 + 1 = 4 numbers.
Example: from -6 to 4 includes 4 - (-6) + 1 = 11 numbers, namely {-6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4}
Answer:
19.2
Step-by-step explanation:
You use the pyth.
15^2+12^2=369
Then find the square root of 392 which is 19.2
I hope this helps! have a good day :)
So for this, we can simplify √63 as such:
![\sqrt{63}=\sqrt{7*9}=3\sqrt{7}](https://tex.z-dn.net/?f=%20%5Csqrt%7B63%7D%3D%5Csqrt%7B7%2A9%7D%3D3%5Csqrt%7B7%7D%20%20)
Using the simplified version of √63, we can solve it:
![3\sqrt{7} -3\sqrt{7} =0](https://tex.z-dn.net/?f=%203%5Csqrt%7B7%7D%20-3%5Csqrt%7B7%7D%20%3D0%20)
Zero is your final answer.
