Un aserradero adquiere maquinaria y equipo para el corte de madera, que va perdiendo valor conforme transcurren los años, hasta

que su valor contable es cero, como indica la gráfica de la función D(x)=(-x^3+2x^2+20x+20)/(x^2+4x+4) que modela esta depreciación en el eje y cada unidad son 20 000 pesos y en el eje x cada unidad es de 3 años.
a) ¿Cuál es el valor inicial del equipo y herramienta? ¿cuánto se ha depreciado al cabo de 12 años?

b) ¿existe un modelo lineal que aproxime los mismos valores que la función D(x)?

c) ¿En cuánto difieren los valores de ambas funciones al cabo de 9 años?

Answer:

y - 10 = 5(x - 15)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (15, 10) and (x₂, y₂ ) = (16, 15)

m = \frac{15-10}{16-15} = \frac{5}{1} = 5

Using (a, b) = (15, 10), then

y - 10 = 5(x - 15)

The answer is actually choice B. To solve for the area of a trapezoid, you would do the formula a+b/2 h.

Answer:

The answer is 46 units

Step-by-step explanation:

You were correct in multiplying 12 by 4. However, you forgot to notice that the corners of every square were only shaded halfway. All you have to do then is subtract 48 by 2.

Answer:

C

Step-by-step explanation:

When you are given any number to an exponent, you need to multiply it by itself as many times as the exponent's number. For example, if you got 4^7, you would multiply 4 * 4 * 4 * 4 * 4 * 4 *4 for a total of 7 times. In this case, it is 1/2 * 1/2 * 1/2 because the exponent is 3, meaning you do that 3 times.
