Question

What is the length of PQ round to the nearest tenth of a unit p(-3 ,7) q(6 ,1)

Answer 1

Answer: The approximate length of PQ is 10.8 unit.

Step-by-step explanation:

Here the coordinates of point P are (-3,7) and the coordinates of Q are (6,1)

Thus, by the distance formula,

The distance between the points P and Q is,

$PQ = \sqrt{(6-(-3))^2+(1-7)^2}$

$=\sqrt{(6+3)^2+(-6)^2$

$=\sqrt{9^2+ 36}$

$=\sqrt{81+36}=\sqrt{117}=10.8166538264\approx 10.8$

Thus, the approximate length of PQ is 10.8 unit.
