Ruby would like to build a ramp for her dog over some stairs. Compute the distance between points C and D
C (10, -1)
D (5, 11)
To compute the distance between points C(10, -1) and D(5, 11), we can use the distance formula:
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Plugging in the values, we get:
Distance = sqrt((5 - 10)^2 + (11 - (-1))^2)
Distance = sqrt((-5)^2 + (12)^2)
Distance = sqrt(25 + 144)
Distance = sqrt(169)
Distance = 13
The distance between points C and D is 13 units.
