Find the distance CD rounded to the nearest tenth. C=(7,-4) d=(-8,-5)
Cd=
To find the distance between points C(7,-4) and D(-8,-5), you can use the distance formula:
Distance = √[(x2 - x1)² + (y2 - y1)²]
Substituting the coordinates, the distance formula becomes:
Distance = √[(-8 - 7)² + (-5 - (-4))²]
Simplifying further:
Distance = √[(-15)² + (-1)²]
Distance = √[225 + 1]
Distance = √226
The distance between points C and D is approximately 15.03 (rounded to the nearest tenth).
To find the distance between points C(7, -4) and D(-8, -5), we can use the distance formula:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
In this case, (x1, y1) = (7, -4) and (x2, y2) = (-8, -5).
So, plugging in the values into the distance formula, we get:
d = sqrt((-8 - 7)^2 + (-5 - (-4))^2)
= sqrt((-15)^2 + (-1)^2)
= sqrt(225 + 1)
= sqrt(226)
Now, to round the distance to the nearest tenth, we can use the rounding rule:
If the decimal part is less than 0.5, round down. If the decimal part is 0.5 or greater, round up.
In this case, the decimal part of sqrt(226) is approximately 0.581.
Since the decimal part is 0.5 or greater, we will round up the distance.
Therefore, Cd ≈ 15.0 (rounded to the nearest tenth).
Even Though Its Not Geography Ill Help
change in x = -15
change in y = -1
distance = sqrt(225+1) = sqrt(226)
