Answer:

5.196 m

Step-by-step explanation:

p = La perpendicular del triángulo es la longitud de la antena.

h = La hipotenusa del triángulo es la longitud del cable conectado a la parte superior del poste = 6 m

\theta = Incline el cable con el suelo = 60^{\circ}

De las funciones trigonométricas sabemos que

\sin\theta=\dfrac{p}{h}\\\Rightarrow p=h\sin\theta\\\Rightarrow p=6\times \sin60^{\circ}\\\Rightarrow p=6\times\dfrac{\sqrt{3}}{2}\\\Rightarrow p=3\sqrt{3}\\\Rightarrow p=3\times 1.732=5.196\ \text{m}

La longitud de la antena es 5.196 m.

Answer:

when x=6, y=30

when x=7.5, y=37.5

Step-by-step explanation:

Just plug in the value of x into the equation y=5x

so when x=6, the equation will be y=5(6).  In this case y=30

when x =7.5, the equation will be y=5(7.5). So y=37.5

Hello : 
v . w = <span>| | v | | × </span><span>| | w | |  cos(</span><span>θ) ....(1)
v(2,0,1)   w(0,1,-3)

</span>v . w = (2)(0)+(0)(1)+(1)(-3) = - 3
| | v | |  = √((2)²+(0)²+(1)²) = <span>√5
</span>| | w |  =  √((0)²+(1)²+(-3)²) = √10
by (1) : 
cos(θ) = (v . w ) /  | | v | | × | | w | |

cos(θ) = = - 3/√50
θ =.....   calculate by 2ind function ( calculator)
