Question

Please help if possible..

Answer 1

Step-by-step explanation:

$P(2, 13)= (x_1, y_1) \:\&\: Q(17, 1)=(x_2, y_2)$

length of segment PQ

$= \sqrt{ {(x_1 - x_2)}^{2} + {(y_1 - y_2)}^{2} } \\ = \sqrt{ {(2 - 17 )}^{2} + {(13 - 1)}^{2} } \\ = \sqrt{ {( - 15 )}^{2} + {(12)}^{2} } \\ = \sqrt{225 + 144} \\ = \sqrt{369} \\ = 19.2093727 \\ \approx \: 19.21 \: units$
