Answer: OPTION D

Step-by-step explanation:

To solve this exercise you must use the formula for calculate the distance  between two points, which is shown below:

d_{(A,B)}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Now, you must substitute the points given in the problem into the formula:

A(-2,-4)

B(-8,4)

d_{(A,B)}=\sqrt{(-8-(-2))^2+(4-(-4))^2}

Then, the result is:

d_{(A,B)}=10units

Answer:

Choice D is correct answer.

Step-by-step explanation:

We have given two points.

A = (-2, -4) and B = (-8, 4)

We have to find length of AB.

We use distance formula to find distance between two points.

d = √(x₂-x₁)²+(y₂-y₁)²

Let A = (x₁,y₁) = (-2, -4) and B = (x₂,y₂) =  (-8, 4)

Putting above values in formula, we have

d = √(-8-(-2))²+(4-(-4))²

d = √(-8+2)²+(4+4)²

d = √(-6)²+(8)²

d = √36+64

d = √100

d = 10 units

Hence , The length of AB is 10 units.

Select all number combinations that COULD make a triangle
tester [92]

Answer:

2 cm, 9 cm, 10 cm

Step-by-step explanation:

To know if a combination is a triangle all you have to do is see if the combinations add up to 180

(2)(9)(10)=180 therefore it is a triangle.

All the other angles do not add up to 180 so they can't be triangles!!

(4)(10)(3) =120

(5)(6)(11) =330

(4)(5)(7) =140

The three vertices of a triangle drawn on a complex plane are represented by 0 + 0i, 4 + 0i, and 0+ 3i. The length of the hypote

Once you have the points they make a 3-4-5 triangle. The two legs are 3 and 4, so the hypotenuse has to be 5. Or you could use the pythagorean theorem a² + b² = c² 3² + 4² = c² 25 = c² c = 5

A circular swimming pool has a diameter of the 26 feet.
kherson [118]
Hey there! :)

The formula for finding area of circles is: π · r²

<em>Remember that radius is half the diameter. To find radius when the diameter is given, divide by 2</em>

d = 26

26 ÷ 2 = 13
_____________________________________________________________

π · r²

r = 13
13² = 13 × 13 = 169

169 × 3.14 = 530.66 = 530.7

The area of the swimming pool is 530.7 ft²

Hope this helps :)

*Please answer before 5:45! I'll award brainliest!*
FromTheMoon [43]

Answer:

A

Step-by-step explanation:

Vertical angles are angles that are formed by 2 lines and are directly accross from each other. They do not share a ray, however they are always the same number of degrees.

so then the answer would be A, ∠ERT and ∠MRC since they are directly across from each other.
