Question

1. Find the distance between the following pairs
of points :
(3/5,2) and (-1/5,1⅖)​

Answer 1

Answer:

apply the distance formula.

Step-by-step explanation:

that is

√(x2 - x1)^2 + (y2-y1)^2

Answer 2

Given:

A(3/5 , 2)

B(-1/5 , 7/5) {solving 1 2/5 gives 7/5)

x1 = 3/5   ,  y1 = 2

x2 = -1/5  ,  y2 = 7/5

to Find:

AB

Formula Used:

$\sqrt{(x2-x1)^{2} + (y2-y1)^{2} }$

Solution:

=$\sqrt{(\frac{-1}{5} -\frac{3}{5} )^{2}+ (\frac{7}{5} -2)^{2} }$

=$\sqrt{(\frac{-1 - 3}{5} )^{2}+ (\frac{7 - 10}{5} )^{2} }$

=$\sqrt{(\frac{-4}{5} )^{2}+ (\frac{-3}{5} )^{2} }$

=$\sqrt{\frac{16}{25} + \frac{9}{25} }$

=$\sqrt{\frac{25}{25}}$

=$\frac{5}{5} = 1$

there fore AB = 1
