Given Information:
Point 1 = ( 2½, -8)
Point 2 = ( 2½, 3)
Required Information:
Distance between two points = d = ?
Answer:
Distance between two points = [tex]d = 11[/tex] [tex]units[/tex]
Step-by-step explanation:
The distance between two points is calculated using
[tex]d = \sqrt{(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2}[/tex] eq. 1
We have (x₁, y₁) = (2½, -8) and (x₂, y₂) = (2½, 3)
Substitute the above points into the eq. 1
[tex]d = \sqrt{(2\textonehalf - 2\textonehalf)^2 + (3 - (-8))^2}[/tex]
[tex]d = \sqrt{(2\textonehalf - 2\textonehalf)^2 + (3 + 8)^2}[/tex]
[tex]d = \sqrt{(0)^2 + (11)^2}[/tex]
[tex]d = \sqrt{0 + 121}[/tex]
[tex]d = \sqrt{121}[/tex]
[tex]d = 11[/tex] [tex]units[/tex]
it is very unclear as what error did Sukant make due to unclear typing!
But I guess, Sukant simply added the x-coordinates together that is
d = 2½ + 2½ = 5 units
Note: 2½ = 5/2 = 2.5
Answer:
He should have used the y-coordinates
Step-by-step explanation:
I don't have one.
