Answer:

Para un punto (x, y), el angulo generado entre el eje x y un rayo que conecta el origen de coordenadas con el punto es tal que:

Tan(θ) = y/x

Cos(θ) = x/(√(x^2 + y^2))

Sin(θ) = y/(√(x^2 + y^2))

Y las otras 3 relaciones trigonometricas son las inversas de las de arriba, entonces:

Ctg(θ) = x/y

Sec(θ) = √(x^2 + y^2)/x

Csc(θ) = √(x^2 + y^2)/y

En este caso tenemos el punto (4, -3), es decir:

x = 4

y = -3

Solo tenemos que reemplazar esos dos valores en las seis ecuaciones de arriba:

Tan(θ) = -3/4

Cos(θ) = 4/(√(4^2 + (-3)^2)) = 4/5

Sin(θ) = -3/(√(4^2 + (-3)^2)) = -3/5

Ctg(θ) = 4/(-3) = -4/3

Sec(θ) =  √(4^2 + (-3)^2)/4 = 5/4

Csc(θ) = √(4^2 + (-3)^2)/-3 = 5/-3 = -5/3

Which of the following statements best describes the graph of −5x + 2y = 1?
Nina [5.8K]

First, we determine that the given equation in this item is a linear equation. Thus, it should be a straight line. With this, we are left with the third and fourth choice. Then, we substitute the given data points to the equation and see if the points satisfy the given.

Choice 3:

<span>            (1,3)   :    (-5)(1) + (2)(3) = 1   TRUE</span>

<span>            (3,8)   :    (-5)(3) + 2(8) = 1      TRUE</span>

<span>            (-3,-7) :    (-5)(-3) + (2)(-7) = 1 TRUE</span>

 

Choice 4:

<span>            (4,-3)  :  (-5)(4) + (2)(-3) ≠ 1     FALSE</span>

<span>            (-1,2)   : (-5)(-1) + (2)(2) ≠ 1     FALSE</span>

<span>            (-4,5)   : (-5)(-4) + (2)(5) ≠ 1    FALSE</span>

 

<span>Thus, the answer is the third choice.</span>
