Find the distance between the two given points. O(-3,-2) and P(-3,4)

aliina [53]

Answer:

$\boxed {\boxed {\sf d= 6}}$

Step-by-step explanation:

Distance can be found using this formula:

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

Where (x₁, y₁) and (x₂, y₂) are the points.

We are given the points O (-3, -2) and P(-3,4). Therefore,

$x_1= -3 \\y_1= -2 \\x_2= -3 \\y_2=4$

Substitute the values into the formula.

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

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

Solve inside the parentheses first.

(-3--3)= -3+3=0
(4--2)= 4+2=6

$d= \sqrt {(0)^2+ (6)^2}$

Solve the exponents.

(0)²= 0*0=0
(6)²= 6*6=36

$d=\sqrt {0+36$

Add.

$d= \sqrt {36$

Take the square root.

$d=6$

The distance is 6.

Un barco que hace cruceros por el mar Caribe dispone de camarotes de una plaza y de dos plazas. Si en total hay 215 camarotes y

prisoha [69]

Answer:

- There are 71 one-quarter cabins and 144 two-seater cabins on the cruise ship.

- Hay 71 cabinas de un asiento y 144 cabinas de dos asientos en el crucero.

Step-by-step explanation:

English Translation

A ship that cruises in the Caribbean Sea has one and two-seater cabins. If there are 215 cabins and 359 seats in total, find out how many cabins there are of each type.

Let the number of one seater cabins be x

Let the number of two seater cabins be y

There are x seats on the one seater cabins and there are 2y seats in total for the two seater cabins

x + y = 215 (eqn 1)

x + 2y = 359 (eqn 2)

Subtract eqn 1 from eqn 2

y = 359 - 215 = 144

x + y = 215

x = 215 - y = 215 - 144 = 71

There are 71 one-quarter cabins and 144 two-seater cabins on the cruise ship.

In Spanish/En español

Deje que el número de cabinas de un asiento sea x

Deje que el número de cabinas de dos plazas sea y

Hay x asientos en las cabinas de un asiento y hay 2 asientos en total para las cabinas de dos asientos

x + y = 215 (ecuación 1)

x + 2y = 359 (ecuación 2)

Resta la ecuación 1 de la ecuación

2 y = 359 - 215 = 144

x + y = 215

x = 215 - y = 215 - 144 = 71

Hay 71 cabinas de un asiento y 144 cabinas de dos asientos en el crucero.

Hope this Helps!!!

What are the ordered pairs of the

Vlad1618 [11]

Answer:

${x}^{2} - 2x + 3 = - 6x \\ = {x}^{2} - 2x + 6x + 3 = 0 \\ \\ = {x}^{2} + 4x + 3 = 0 \\ = (x + 1)(x + 3) \\ = x = - 1and \: x = - 3$

a rectangle has a diagonal 20 inches long that forms angles of 60 and 30 with the sides. find the perimeter of the rectangle.

kakasveta [241]

Answer:

P = 47.32

Step-by-step explanation:

This triangle is a special triangle. Because it is 30-60-90 it will have measurements similar to $1 - \sqrt{3} - 2$ . If the longest side is 20 then it corresponds to 2. This means the shortest side of 1 corresponds to half this or 10.

So the triangle will have sides $10 - 10\sqrt{3} - 20$ .

To find the perimeter add all these lengths.

$P = 10 + 10\sqrt{3} +20\\P = 30+10\sqrt{3} \\ P = 47.32$
