Question

Work out the lengh of RS gue your answer to 3 significant figures

Answer 1

Answer:

RS ≈ 5.83 units

Step-by-step explanation:

Calculate RS using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = R(- 3, 1) and (x₂, y₂ ) = S(2, 4)

RS = $\sqrt{(2+3)^2+(4-1)^2}$

     = $\sqrt{5^2+3^2}$

     = $\sqrt{25+9}$

     = $\sqrt{34}$ ≈ 5.83 ( to 3 significant figures )
