Question

What is the distance between points A and C? 3.3 units 3.6 units 5.2 units 7.8 units

Answer 1

Answer:

AC ≈ 7.8 units

Step-by-step explanation:

Calculate the distance d using the distance formula

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

with (x₁, y₁ ) = A (- 4, - 4 ) and (x₂, y₂ ) = C (2, 1 )

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

      = $\sqrt{(2+4)^2+(1+4)^2}$

      = $\sqrt{6^2+5^2}$

     = $\sqrt{36+25}$

     = $\sqrt{61}$

     ≈ 7.8 ( to 1 dec. place )
