Question

what is the distance between P(0,0) and Q(5,12)

Answer 1

PQ=root [(0-5)^2 +(0-12)^2]
PQ=root [(5)^2+(12)^2]
PQ=root[25+144]
PQ=root(21361)
PQ=146.1540283

Answer 2

Hello and Welcome to OpenStudy @hayleymarie4280 ! :)
\[distance formula: \sqrt{(x _{2}-x _{1})^{2} + (y _{2}-y _{1})^{2}}\]when given points (x1, y1) and (x2, y2)
so plug in
x2 = 5
x1 = 0
y2 = 12
y1 = 0
and you will get
\[\sqrt{(5-0)^2+(12-0)^2}~=~~?\]can you solve from there? ^_^
