Question 14

Find the distance between the points. Round to the nearest hundredth, if necessary. (-4, 8), (4, 1)
A) 9.00
B) 7.00
C) 10.63
D) 12.04
E) 12.37

Accepted Answer

We use the distance formula to find the distance between two points:

d = sqrt((x2-x1)^2 + (y2-y1)^2)

Plugging in the coordinates given, we get:

d = sqrt((4-(-4))^2 + (1-8)^2)
d = sqrt((8)^2 + (-7)^2)
d = sqrt(64 + 49)
d = sqrt(113)

Rounding to the nearest hundredth, we get:

d ≈ 10.63

Therefore, the best choice is C) 10.63.
