I need some help please

Mathematics
1 answer:
Ket [755]3 years ago

Answer:

3\sqrt{5}

Step-by-step explanation:

View the distance as a hypotenuse of a triangle ΔABC (∠C = 90°).

Use Pythagorean theorem:

AB = y1 - y2 = 9 - 6 = 3

AC = x1 - x2 = 4 - (-2) = 6

Now calculate BC which is also the distance needed:

BC^{2} =AC^{2} +AB^{2}

BC^{2} = 6^{2} + 3^{2} = 45

BC = \sqrt{45} = \sqrt{3 * 3 * 5} (BC > 0)

BC = 3\sqrt{5}

Make me the brainliest ;)

slope = rise over run = y/x

A (-1,3) slope = 3/-1 = -3

B (1,2) slope = 2/1 = 2

C (-3,-1) slope = -1/-3 = 1/3

2 lines need to be negative reciprocals in order to be a right triangle

negative reciprocal of -3 is 1/3

 so this is a right triangle

What is the distance between 5,4 and -1,1
spayn [35]

Answer:

3\sqrt{5}

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 ) = (5, 4) and (x₂, y₂ ) = (- 1, 1)

d = \sqrt{(-1-5)^2+(1-4)^2}

   = \sqrt{(-6)^2+(-3)^2}

   = \sqrt{36+9}

   = \sqrt{45}

   = 3\sqrt{5} ← exact value

   ≈ 6.71 ( to 2 dec. places )

What graph represents a function?
vredina [299]

Answer:

Bottom answer

Step-by-step explanation:

Although I cannot see the answer labels, the answer is the very bottom graph.  The way you can find a functional graph is if you add vertical lines going down and that there is only one point that crosses it, not two.  It is kind of difficult for me to explain, so if you need help, I suggest you look up how to know when a graph is a function or not.
