Question
What is the distance between the two points (13, -7) and (4, 33)?
Solution
To find the distance between two points in a plane, we can use the distance formula derived from the Pythagorean theorem. The distance d between two points (x1, y1) and (x2, y2) is given by:
d = sqrt[(x2-x1)² + (y2-y1)²]
Here, our points are (13, -7) and (4, 33). So, x1 = 13, y1 = -7, x2 = 4, and y2 = 33.
Substituting these values into the formula, we get:
d = sqrt[(4-13)² + (33-(-7))²] d = sqrt[(-9)² + (40)²] d = sqrt[81 + 1600] d = sqrt[1681]
Therefore, the distance between the points (13, -7) and (4, 33) is sqrt[1681] = 41 units.
