Please check my answer~
Find the distance between points C (4,12) and D (-2,5) to th3 nearest tenth.
d=sqrt(-2,4)^2+(5-12)^2
d=sqrt36+49
d=sqrt85
d=9.2
oops I meant d=sqrt(-2-4)^2+(5-12)^2
yep
But I'd just leave it as √85
That is its exact value, not some decimal approximation.
To find the distance between two points on a coordinate plane, you can use the Euclidean distance formula:
d = √((x2 - x1)^2 + (y2 - y1)^2)
Let's calculate the distance between points C(4, 12) and D(-2, 5) using this formula:
First, identify the coordinates of point C as (x1, y1) = (4, 12) and the coordinates of point D as (x2, y2) = (-2, 5).
Now, substitute these values into the formula:
d = √((-2 - 4)^2 + (5 - 12)^2)
d = √((-6)^2 + (-7)^2)
d = √(36 + 49)
d = √85
d ≈ 9.2 (rounded to the nearest tenth)
So, the correct answer for the distance between points C (4,12) and D (-2,5) to the nearest tenth is approximately 9.2 units.
