Question 880027: Hi,
1. What is the distance between these two points: (8, 10) and (4, -5)?
Round answer to the nearest hundredths.
Distance formula
d = sqrt[(x2-x1)^2+(y2-y1)^2]
x1=8 y1=10 x2=4 y2= -5
d=sqrt[(4-8)^2+(-5-10)^2]
=sqrt [(-4)^2+(-15)^2]
=sqrt [(16+225)]
=sqrt [241]
=15.52
2. What is the distance between these two points: (-8,10) and (-4, -10)?
Round answer to the nearest hundredths.
x1= -8 y1=10 x2= -4 y2= -10
d=sqrt[(-4-(-8))^2 +(-10-10)^2]
=sqrt[(-4+8)^2 +(-20)^2]
=sqrt[(4)^2+(-20)^2]
=sqrt[(16+400)]
=sqrt [416]
=20.40
thank you!
