Answer:

B

Step-by-step explanation:

Using the trigonometric identities

• cscx = \frac{1}{sinx} and secx = \frac{1}{cosx}

Consider the left side

cscx sec x = \frac{1}{sinx} × \frac{1}{cosx} = \frac{1}{sinxcosx}

Consider the right side

2 csc2x = \frac{2}{sin2x} = \frac{2}{2sinxcosx} = \frac{1}{sinxcosx}

left side = right side hence identity is verified

Un grupo de compañeros de clase está planificando un viaje de cada uno de ellos hicieron aportación de 14 pesos para gastos de v
Crank

Answer:

$14.8

Step-by-step explanation:

There is a mistype in the question. It should say: ... <em>si cada uno de ellos hicieron una contribución de </em><em>dieciseis</em><em> pesos...</em>

So if everybody contributes $14, they make a total of 14*x, where x denotes the number of students. In this scenario, $4 are left, calling y to the cost of the trip, then:

14*x = y - 4 (eq. 1)

In the other scenario, everybody contributes $16 and $6 are in excess, so

16*x = y + 6 (eq. 2)

subtracting eq. 1 to eq. 2:

16*x - 14*x = y + 6 - (y - 4)

2*x =  y + 6 - y + 4

2*x = 10

x = 10/2 = 5

Replacing this value in eq. 1:

14*5 = y - 4

70 + 4 = y

y = $74

If every student pays: 74/5 =  $14.8, then they would get altogether the exact cost of the trip
