Question

please answer from image bellow

Answer 1

Step-by-step explanation:

Let P = (-2 5) Q = (4, -3)

P = -2 i + 5 j Q = 4i -3j

PQ = (-2 i + 5 j) -( 4i -3j)

PQ = -6i + 8j

$PQ = \sqrt{ {x}^{2} + {y}^{2} }$

$PQ = \: \sqrt{ {( - 6)}^{2} + {8}^{2} }$

$PQ = \sqrt{36 + 64}$

$PQ = \: \sqrt{100}$

$PQ = \: 10$
