Find the distance between the points (-2, 4) and (4, -6).<br> 0 212<br> 2/(10)<br> O2V(34)
Fittoniya [83]

Answer:

2\sqrt{34}

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √(x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (4, - 6)

d = \sqrt{(4+2)^2+(-6-4)^2}

  = \sqrt{6^2+(-10)^2}

  = \sqrt{36+100}

  = \sqrt{136} = \sqrt{4(34)} = \sqrt{4} × \sqrt{34} = 2\sqrt{34}

A pie is made using 2 cups of sugar for every 3 cups of flour. Max knows he needs 15 cups of flour to make enough pies. How many
PolarNik [594]

Answer: 10 cups of sugar

Step-by-step explanation:

Cups of sugar : Cups of flour

                    2 : 3

                    ? : 15

Cross multiply

3? = 15 × 2

3? = 30

Divide both sides by 3

? = 10

He needs 10 cups of sugar.
