Math Problem Statement

Find the distance between each pair of points. Simplify all roots.

Solution

The problem asks to find the distance between each pair of points and simplify the square roots. 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}

Let's go through each pair of points one by one.

1. Points on the graph (I will estimate the points for clarity):

  • Estimated points from graph 1: (2,1)(2, 1) and (2,5)(-2, 5)

Using the distance formula: d=((22)2+(51)2)=(4)2+(4)2=16+16=32=42d = \sqrt{((-2 - 2)^2 + (5 - 1)^2)} = \sqrt{(-4)^2 + (4)^2} = \sqrt{16 + 16} = \sqrt{32} = 4\sqrt{2}

2. Points from graph 2:

  • Estimated points from graph 2: (3,4)(3, 4) and (2,2)(-2, -2)

Using the distance formula: d=((23)2+(24)2)=(5)2+(6)2=25+36=61d = \sqrt{((-2 - 3)^2 + (-2 - 4)^2)} = \sqrt{(-5)^2 + (-6)^2} = \sqrt{25 + 36} = \sqrt{61}

3. Points (5,8)(5, 8) and (2,5)(2, 5):

d=((25)2+(58)2)=(3)2+(3)2=9+9=18=32d = \sqrt{((2 - 5)^2 + (5 - 8)^2)} = \sqrt{(-3)^2 + (-3)^2} = \sqrt{9 + 9} = \sqrt{18} = 3\sqrt{2}

4. Points (7,8)(7, 8) and (5,1)(-5, -1):

d=((57)2+(18)2)=(12)2+(9)2=144+81=225=15d = \sqrt{((-5 - 7)^2 + (-1 - 8)^2)} = \sqrt{(-12)^2 + (-9)^2} = \sqrt{144 + 81} = \sqrt{225} = 15

5. Points (1,6)(-1, -6) and (4,5)(4, -5):

d=((4+1)2+(5+6)2)=(5)2+(1)2=25+1=26d = \sqrt{((4 + 1)^2 + (-5 + 6)^2)} = \sqrt{(5)^2 + (1)^2} = \sqrt{25 + 1} = \sqrt{26}

6. Points (6,2)(6, 2) and (4,1)(4, -1):

d=((46)2+(12)2)=(2)2+(3)2=4+9=13d = \sqrt{((4 - 6)^2 + (-1 - 2)^2)} = \sqrt{(-2)^2 + (-3)^2} = \sqrt{4 + 9} = \sqrt{13}

7. Points (6,1)(-6, 1) and (3,5)(3, -5):

d=((3+6)2+(51)2)=(9)2+(6)2=81+36=117=313d = \sqrt{((3 + 6)^2 + (-5 - 1)^2)} = \sqrt{(9)^2 + (-6)^2} = \sqrt{81 + 36} = \sqrt{117} = 3\sqrt{13}

8. Points (2,2)(2, -2) and (7,8)(7, 8):

d=((72)2+(8+2)2)=(5)2+(10)2=25+100=125=55d = \sqrt{((7 - 2)^2 + (8 + 2)^2)} = \sqrt{(5)^2 + (10)^2} = \sqrt{25 + 100} = \sqrt{125} = 5\sqrt{5}
