Question 1136726
<br>
Use the distance formula, aka the Pythagorean Theorem:<br>
{{{(sqrt(11-9k))^2 = (1-(1-k))^2+(2k-1)^2}}}<br>
Basic algebra leads to a quadratic equation that does not factor, so the answers are ugly irrational numbers.<br>
You can do the work to find them.<br>
(Or check to see if you have posted the problem correctly; this kind of problem, as a learning exercise, would usually have rational numbers for answers.)
