Question
If A = (7, 9) and B = (3, 12), what is the length of ?A.7 unitsB.6 unitsC.5 unitsD.4 units
Solution
The question seems to be incomplete. If you're asking for the length of the line segment AB, we can use the distance formula which is derived from the Pythagorean theorem. The distance d between two points A and B with coordinates (x1, y1) and (x2, y2) is given by:
d = sqrt[(x2-x1)² + (y2-y1)²]
Here, A = (7, 9) and B = (3, 12). So, (x1, y1) = (7, 9) and (x2, y2) = (3, 12).
Substituting these values into the formula gives:
d = sqrt[(3-7)² + (12-9)²] d = sqrt[(-4)² + (3)²] d = sqrt[16 + 9] d = sqrt[25] d = 5 units
So, the length of the line segment AB is 5 units. Therefore, the answer is C.5 units.
