12.4
In this problem, we need to use the distance formula to determine the distance between the two points.
__________________________________________________
The distance formula is as follows:
d = √(2 – 1)² + (y2 – y1)²
Where:
- d = distance
- (1, y1) = coordinates of the first point
- (2, y2) = coordinates of the second point
__________________________________________________
For this problem, we need to follow these steps (refer to the distance formula mentioned above) :
Subtract -4 and -7, we get 3:
√3² + (12 - 0)²
Raise 3 to the power of 2, we get 9:
√9 + (12 - 0)²
Subtract 0 from 12, we get 12:
√9 + 12²
Raise 12 to the power of 2, we get 144:
√9 + 144
Add 9 and 144, we get 153:
√153
Root 153, we get:
12.369316877
Round it to the nearest tenth:
36 is nearest to 40, so we get 12.40
Simplifying it, we get the final result as:
12.4
Hope this helps :)
