    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=\sqrt{(5-2)^2+(0-(-2))^2}

    Now we need to simplify/solve this expression

    =\sqrt{3^2+2^2}

    =\sqrt13

    Therefore the answer is C!

    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
