Dos personas A y B , se encuentran en la orilla de un río, separadas entre sí 200 m y en la orilla opuesta en el punto C, se enc
Kryger [21]

Answer:

La distancia de C con respecto a A es de 197.788 metros.

Step-by-step explanation:

A manera de imagen adjunta construimos una representación del enunciado del problema, la cual representa a un triángulo cuyos tres ángulos son conocidos y la longitud del segmento AB, medida en metros, son conocidos. Por medio de la Ley del Seno podemos calcular la longitud del segmento AC (distancia de C con respecto a A), medida en metros:

\frac{AB}{\sin C} = \frac{AC}{\sin B} (1)

Si sabemos que B = 57^{\circ}, C = 58^{\circ} y AB = 200\,m, entonces la longitud del segmento AC es:

AC = AB\cdot \left(\frac{\sin B}{\sin C} \right)

AC = (200\,m)\cdot \left(\frac{\sin 57^{\circ}}{\sin 58^{\circ}} \right)

AC = 197.788\,m

La distancia de C con respecto a A es de 197.788 metros.

If x-y=√3, x²-y²=√5 & a²-a√3+1=0, then find out the value of x+y
Lemur [1.5K]

Answer:

√15/3

Step-by-step explanation:

x² - y² =√5

(x +y)*(x -y) = √5

(x +y) * √3 = √5

x+y  = √5 / √3

x +y = √5*√3 / √3*√3

x +y = √15/3

Mazyrski [523]

Answer:

a) The rate of change is 3.5

b) The rate of change represents the price of a single cookie. $3.5

Step-by-step explanation:

a) To determine the rate of change along the graph, select a pair on the graph as;

(2,7)  and (8,28)

Rate of change, m= change in y/change in x

m=28-7/8-2 = 21/6 =7/2 = 3.5

b)

The equation of the relationship can be written as;

y=3.5 x + 0  where y is the amount collected and x is the number of cookies sold.

The slope here represents the price per cookie in $, $3.5

X+8=-15 help again sorryyy
suter [353]
X by its self is always 1x

1x+8=-15 you have to get rid of 8 by subtracting on both sides

1x=-23 now get rid of 1 by dividing on both sides

x=-23
