Find the distance between the pair of points.
1) (1,5) and (-4,-1)

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (1, 5) and (x₂, y₂ ) = (- 4, - 1)

d =

   =

   =

   = ≈ 7.8 ( to 1 dec. place )

answer4 to the second power is 16

and 4 to the third power is 64,

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
