Find the distance between these points: (-3, 8) and (-5,1)

irina1246 [14]

Answer:

7.28011

Step-by-step explanation:

X1 =-3

X2 =-5

Y1 =8

Y2 =1

Distance Formula = √(X2-X1)²+ (Y2-y1)²

Step 1. calculate (X2-X1)²

(-5 - -3)2 = 4

Step 2. calculate (Y2-Y1)²

(1 - 8)2 = 49

Step 3. calculate √4 + 49

= 7.28011

$\\ \sf\longmapsto A=(1-4)-(2+1)$

$\\ \sf\longmapsto A=-3-3$

$\\ \sf\longmapsto A=-6$

$\\ \sf\longmapsto B=(3-\dfrac{1}{2})-(2-4)$

$\\ \sf\longmapsto B=\left(\dfrac{5}{2}\right)+2$

$\\ \sf\longmapsto B=\dfrac{5+4}{2}$

$\\ \sf\longmapsto B=\dfrac{9}{2}$

Now

$\\ \sf\longmapsto AB=-6\times \dfrac{9}{2}$

$\\ \sf\longmapsto AB=-3(9)$

$\\ \sf\longmapsto AB=-27$

BA

$\\ \sf\longmapsto \dfrac{9}{2}\times (-6)$

$\\ \sf\longmapsto 9(-3)$

$\\ \sf\longmapsto -27$

Observed:-

$\\ \sf\longmapsto AB=BA$
