Find the distance between (3,-6) and (2,-4). please help

Mathematics

Advocard [28]3 years ago

Answer:

\sqrt{99}

Step-by-step explanation:

you can use the distance formula to find the distance between two given points.

the distance formula is:

d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}

so if you simply plug in you get:

d = \sqrt{(2 - 3)^2 + (-4-(-6))^2}

simplify

d = \sqrt{(-1)^2 + (-10)^2}\\

simplify again

d = \sqrt{-1 + 100}\\

and again

d = \sqrt{99}\\

and you have an answer

(look at image) can i get help with these two?
serg [7]

Answer:

1. x = 2, AC = 30, AB - 4

2. y = 4, AB = 34, BC = 34

Step-by-step explanation:

1. AB + BC = AC so 26 + (10 - 3x) = 14x +2 and then add 3x to both sides and subtract 2 from both sides to get x on one side and an integer on the other side which is 34 = 17x and then divide 17 from both sides to get x = 2 and then substitute x into the AC and AB equations to find the values its equal to.

2. The symbol in the given means that the two lengths are congruent which means they are equal to each other so you put the two equations equal to each other and solve for y. 9y -2 = 14 + 5y, so subtract 5y from both sides and add two to both sides to get 4y = 16 and then divide both sides by 4 to get y = 4 and then substitute in the answer to find the lengths of AB and BC.

Which of the following statements are correct? Select all that apply.
Marizza181 [45]
For a 7 sides polygon which is called heptagon or septagon
Interior angles = (7-2)*180/7 = 128.57°
Exterior angle = 180 - 128.57 = 51.43°
Central angle = 360/7 = 51.43°

The statements which are correct:

<span>3. The regular polygon ABCDEFG can be broken down into 2 isosceles trapezoids and 1 isosceles triangle
</span>
<span>5. The central angle of the polygon ABCDEFG is about 51.43° and each interior angle is about 128.57°
</span>
<span>7. The central angle ABCDEFG is the same measure of the exterior angle </span>

What is the equation of the line written in general form
Vesnalui [34]

Answer:

y = -x + 2.

or

x + y - 2 = 0 (Standard form).

Step-by-step explanation:

Its slope (m) is -1 and y intercept (c) is at y = 2.

y = mx + c

So it's:

y = -1x + 2

Standard form is:

x + y - 2 = 0.

I'm not sure what you mean by General Form.

Ratio of 2:3 white flour to whole wheat flour to total of 10 cups flour
LenaWriter [7]
White flour makes up 2 / (2+3) of the total 10 cups:  2/5 of the total 10 cups.

2/5 times 10 is 4 cups.

You'll need 4 cups white flour and 6 cups whole wheat flour, making a total of 10 cups of flour.
