Answer:

C

Step-by-step explanation:

(2,-5) move up three steps is (2, -2). if you draw it on a paper(and draw lines to connect them), you can see that they form a right triangle. apply a²+b²=c² and you should get 3²+2²=(√13)²

First we need to find the point after the translation of 3 units up.

(2,-5)->(2,-2)

Now we have the point (2,-2) we just need to use the difference formula to find the distance between this point and (5,0)

Distance=[tex]\sqrt{(5-2)^2+(0-(-2))^2}[/tex]

Now we need to simplify/solve this expression

=[tex]\sqrt{3^2+2^2}[/tex]

=[tex]\sqrt13[/tex]

Therefore the answer is C!
