what is the distance between (-5,0) and (-9,11)? Please helpppppp!!!
use your distance formula:
√((-9-(-5))^2+(11-0)^2) = √(14^2+11^2) = √(196+121) = √317
dangers of early morning arithmetic ....
√((-9-(-5))^2+(11-0)^2)
= √((-4)^2 + 11^2)
= √(16+121) = √137
early indeed. Thanks for checking.
To find the distance between two points in a coordinate plane, you can use the distance formula. The distance formula is derived from the Pythagorean theorem and is given by:
distance = √((x2 - x1)^2 + (y2 - y1)^2)
Let's apply this formula to find the distance between the given points (-5, 0) and (-9, 11):
Step 1: Identify the coordinates of the two points.
Point 1: (x1, y1) = (-5, 0)
Point 2: (x2, y2) = (-9, 11)
Step 2: Plug the values into the distance formula.
distance = √((-9 - -5)^2 + (11 - 0)^2)
Step 3: Simplify the expression.
distance = √((-9 + 5)^2 + (11)^2)
= √((-4)^2 + (11)^2)
= √(16 + 121)
= √137
Therefore, the distance between the points (-5, 0) and (-9, 11) is √137, which is approximately 11.704.
