What is the distance between points A and C?<br> 3.3 units<br> 3.6 units<br> 5.2 units<br> 7.8 units
artcher [175]

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 )
