What is the distance between points s and u?

round to the nearest tenth of a unit.

3.3 units
6.4 units
8.1 units
12.0 units

Distance = sqrt((6-2)^2 +(8-1)^2)
sqrt(16 +49)
sqrt(65)
8.06
round to 8.1 units

ANSWER

The correct answer is C.



EXPLANATION

The given points are,


We use the distance formula to determine the distance between the two points.



We substitute the points to obtain,



We simplify to obtain,



We further simplify this to obtain,





This evaluates to,



We round to the nearest tenth to get,
