Math Problem Statement

find the mid point, distance, from the two points (4,2) and (-3,4) as well as their distance from the origin

Solution

To solve this, let's find the midpoint, the distance between the two points, and each point’s distance from the origin.

1. Midpoint

The formula for the midpoint between two points (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) is:

(x1+x22,y1+y22)\left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right)

For points (4,2)(4, 2) and (3,4)(-3, 4):

Midpoint=(4+(3)2,2+42)=(12,3)\text{Midpoint} = \left( \frac{4 + (-3)}{2}, \frac{2 + 4}{2} \right) = \left( \frac{1}{2}, 3 \right)

2. Distance Between the Points

The distance formula between two points (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) is:

d=(x2x1)2+(y2y1)2d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

For points (4,2)(4, 2) and (3,4)(-3, 4):

d=(34)2+(42)2=(7)2+(2)2=49+4=537.28d = \sqrt{(-3 - 4)^2 + (4 - 2)^2} = \sqrt{(-7)^2 + (2)^2} = \sqrt{49 + 4} = \sqrt{53} \approx 7.28

3. Distance of Each Point from the Origin

The distance from the origin (0,0)(0, 0) to a point (x,y)(x, y) is given by:

d=x2+y2d = \sqrt{x^2 + y^2}

For (4,2)(4, 2):

d=42+22=16+4=204.47d = \sqrt{4^2 + 2^2} = \sqrt{16 + 4} = \sqrt{20} \approx 4.47

For (3,4)(-3, 4):

d=(3)2+42=9+16=25=5d = \sqrt{(-3)^2 + 4^2} = \sqrt{9 + 16} = \sqrt{25} = 5

Summary

  • Midpoint: (12,3)\left( \frac{1}{2}, 3 \right)
  • Distance between points: 537.28\sqrt{53} \approx 7.28
  • Distance from origin:
    • For (4,2)(4, 2): 204.47\sqrt{20} \approx 4.47
    • For (3,4)(-3, 4): 55
