Question

Find the distance from Q: (5.7 , 2.6) to R: (-3, 5.9)

Answer 1

It would be around 9.304. so you'd round to the nearest tenth 9.3

Answer 2

The distance formula

the distance between (x1,y1) and (x2,y2) is
$D= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
so
distnace between (5.7,2.6) and (-3,5.9) is
$D= \sqrt{(-3-5.7)^2+(5.9-2.6)^2}$
$D= \sqrt{(-8.7)^2+(3.3)^2}$
$D= \sqrt{75.69+10.89}$
$D= \sqrt{86.58}$

the distance from Q to R is √86.58 or aprox 9.3048374515624935767985185932756 units
