D. 3√14 /14

Step-by-step explanation:

given that cot(θ)= -√5/3 and cos(θ) < 0

cot(θ)= -√5/3 and cos(θ) < 0, the angle should be on quadrant II.

cot(θ)= -√5/3 => x = -√5 , y = 3

h = √(-3)²+5 =√14

so, sin(θ) = y/h = 3/√14 = 3√14 /14

Tamiku [17]

Answer:

Step-by-step explanation:

Step one:

Given that membership is $9 and the cost per visit is $1

let the number of visits be x

and the total cost be y

the total cost for the situation is modeled as

y=mx+c-----equation of a line

Step two:

given that x=23, we can solve for the totals cost as

by substituting we have

y=1*23+9

y=23+9

y=32

The total cost for 23 visits is $32

La función y = 20000 + 1500x relaciona el valor total a pagar por un servicio de fletes y la distancia recorrida, en kilómetros,

suter [353]

Answer:

Los resultados están debajo.

Step-by-step explanation:

Dada la siguiente información:

y = 20.000 + 1.500x

Siendo:

y= costo total

x= kilometros recorridos

Entonces, si recorrio 20km:

y= 20.000 + 1.500*20

y= $50.000

Ahora, si pago $140.000, cuantos km recorrio:

140.000= 20.000 + 1.500*x

120.000/1.500= x

x= 80km

boyakko [2]

Answer:

Solution given:

f(x) = $\frac{1}{9}$ x-2

let f(x)=y

y = $\frac{1}{9}$ x-2

interchanging role of x and y

x= $\frac{1}{9}$ y-2

x+2= $\frac{1}{9}$ y

y=9(x+2)

y=9x+18

F-¹(x)=9x+18

and

F-¹(-1)=9*-1+18=-9+18=9
