Question

What is the distance etween (-1,2) and (2,7)

Answer 1

Answer:

d(A,B)=square root of 34 ≈ 5.831

Answer 2

Answer:

$\sqrt{34}$

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (2, 7)

d = $\sqrt{(2+1)^2+(7-2)^2}$

  = $\sqrt{3^2+5^2}$

  = $\sqrt{9+25}$ = $\sqrt{34}$ ← exact distance
