Question

What the distance between (2,1) and (-5,8)

Answer 1

Exact form = 7 √2
Decimal form= 9.899

Answer 2

Answer:

$\sqrt{98}$ or 9.89949

Step-by-step explanation:

use the distance formula

d=$\sqrt{(x_{2}-x_{1} )^{2} +(y_{2}-y_{1})^{2} }$

d=$\sqrt{(-5-2)^{2}+(8-1)^{2} }$

d=$\sqrt{(-7)^{2} +(7)^{2} } \\\\\sqrt{49+49}$

d=$\sqrt{98}$ or 9.89949
