## anonymous 4 years ago What is the distance between P(–4, 3) and Q(6, 1)? Round to the nearest tenth

1. anonymous

distance formula

2. anonymous

sqrt(104z)

3. myininaya

$d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$

4. anonymous

10^2 + 2^2 = 104 sqrt(104)

5. anonymous

sqrt(104)

6. anonymous

d z wz mistake

7. myininaya

$\text{ where} (x_1=-4,y_1=3) \text{ and} (x_2=6, y_2=1)$

8. anonymous

pythagoras. from -4 to 6 is 10 from 3 to 1 is 2 $10^2+2^2=d^2$ $d=\sqrt{100+4}$

9. anonymous

$\sqrt{104}$ = 10.198039027185 ans : 10.2
