La distancia entre Rosa y María es de 581,04 m

<h3>¿A que distancia estan Rosa y María?</h3>

Digamos que ambas comienzan en el punto (0m, 0m), y que Rosa se mueve en el eje x-positivo.

Si Rosa se mueve 300m, entonces su nueva posición va a ser:

(300m, 0)

Por otro lado, María se mueve en una dirección definida por el angulo 35°10' con respecto al eje x-positivo, si ella se mueve 800 metros, las nuevas componentes de su posición van a ser:

  • componente x = 800m*cos(35.167°) = 653.98m
  • componente y = 800m*sin(35.167° ) = 460.77m  

Donde se uso:

60' = 1°

10' = (10/60)° = 0.167°

Entonces su nueva posicion va a ser (654.52m, 460m).

Ahora, recordar que la distancia entre dos puntos (x₁, y₁) y (x₂, y₂) esta dada por:

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

En este caso, queremos calcular la distancia entre los puntos:

(300m, 0m) y (653.98m, 460.77m).

d = \sqrt{(460.77m)^2 + (653.98m - 300m)^2} = 581.04 m

Así podemos concluir que la opción correcta es la primera, 581.04.

Solve for B A= 6B +C
dimulka [17.4K]

B = \frac{A - C}{6}

isolate 6B by subtracting C from both sides

A - C = 6B ( divide both sides by 6 )

B = \frac{A - C}{6}

An 8 ounce cup of gourmet coffee costs 4:50. If the unit price remains the same, how much would 3 quarts of coffee cost?
Hunter-Best [27]

Answer:

$54 would 3 quarts of coffee cost

Step-by-step explanation:

Unit rate defined as the rate are expressed as a quantity as 1 such that 3 miles per hour or 5 meter per second.

Use the conversion:

1 ounce = 0.03125 quarts.

As per the statement:  An 8 ounce cup of gourmet coffee costs $ 4.50.

Convert 8 ounces in quarts.

1 ounces = 0.03125 quarts

8 ounces = 0.25 quarts.

\text{Unit rate per quartz} = \frac{4.50}{0.25} = \$ 18

We have to find the cost for 3 quarts of coffee.

\text{Total cost} = \text{Unit rate per quarts} \times 3

Substitute the given values we have;

\text{Total Cost} = 18 \times 3 = \$54

Therefore, $54 would 3 quarts of coffee cost.

What is the inverse of the function f(x)=-x?
svp [43]
To find the inverse we have to first change the function notation to 'y'

So

f(x) = -x becomes y = -x

Next, we have to switch the x and y values

So, y = -x becomes x = -y

Now, we have to solve for y.

y = -x

So the inverse of f(x) = -x is:

f^{-1}(x) = -x
