Answer:

11.25 pesos cada uno

Step-by-step explanation:

En esta pregunta el precio al que contrataron el autobus es un precio fijo, asi que tenemos que calcular este precio fijo primero. Esto lo hacemos multiplicando los 30 alumnos por los 15 pesos que tienen que pagar cada uno...

30 * 15 = 450 pesos

Vemos que el autobus tiene un precio fijo de 450 pesos, ahora podemos dividir este precio fijo por los 40 alumnos que fueron en el viaje para calcular cuanto tiene que pagar cada uno

450 / 40 = 11.25

Ahora podemos ver que cada uno de los 40 alumnos tendran que pagar 11.25 pesos cada uno

y^2 + 625 = 4225 
y^2 = 3600 take the square root of both sides 
y=60

Given the function: f(x) = 2x3 - 3/2x, find f(-4).
Sergeu [11.5K]

Answer:

D) -122

Step-by-step explanation:

Given:

f(x) = 2x^3-\frac{3}2x

We need to find f(-4).

Now by substituting the value of x =-4 in above equation we get;

f(-4)= 2\times(-4)^3-\frac{3}{2}\times(-4)\\

By using PEDMAS we will solve for exponential function first we get;

Now we know that (-4)^3=-64

So we get;

f(-4)= 2\times(-64)-\frac{3}{2}\times(-4)\\

Now using PEDMAS we will solve division.

f(-4)= 2\times(-64)-1.5\times(-4)

Now using PEDMAS we solve multiplication.

f(-4)= -128+6

Finally by subtraction we get;

f(-4)= -122
