Answer: [tex]2\sqrt{34}[/tex] or, as a decimal, 11.7.
Step-by-Step Explanation:
1. Use the distance formula and substitute the values of the two ordered pairs.
[tex]\sqrt{(2-(-4))^{2}+(2-(-8))^{2}}[/tex]...
2. Multiply -1 by -4.
[tex]\sqrt{(2+4)^2+(2-(-8))^2\\}[/tex] ...
3. Add 2 and 4.
4. Raise 6 to the power of 2.
[tex]\sqrt{36+(2-(-8))^2}[/tex]...
5. Multiply -1 by -8.
6. Add 2 and 8.
7. Raise 10 to the power of 2.
[tex]\sqrt{36+100}[/tex] ...
8. Add 100 and 36.
9. Rewrite 136 as 2² · 34.
10. After factoring 4 out of 136 and rewriting as ... [tex]\sqrt{2^{2}(34)}[/tex], pull out terms from under the radical. It should look like this now: [tex]2\sqrt{34}[/tex]. That is your final answer!!
Hope that helps! Note: the unrounded decimal is 11.66190378.
