Question

"Find the distance between P (1,2) and Q (4.5, 10.75)

The distance between P and Q is____"

PLEASE HELP ASAP!!!!!!

Answer 1

Explanation:

Use distance formula.

(1 , 2) Q(4.5, 10.75)

Distance =
`\sqrt{(x_(2)-x_(1))^(2)+(y_(2)-y_(1))^(2)} \\\\`

`= \sqrt{(4.5-1)^(2)+(10.75-2)^(2)} \\\\\\=\sqrt{(3.5)^(2)+(8.75)^(2)} \\\\= √(12.25+76.5625) \\\\= √(88.8125)\\\\= 9.42 units`
