What are the possible rational zeros of f(x) = x4 + 2x3 − 3x2 − 4x + 20? (1 point)

Montano1993 [528]

The possible rational zeros of polynomial function $f(x) = x^4 + 2x^3 - 3x^2-4x + 20$ could be only among the divisors of the free term of this polynomial function.

The free term is 20 and the divisors of 20 are:

$\pm 1, \pm 2, \pm 4, \pm 5, \pm 10, \pm 20.$

A sculptor needs to lift a piece of marble.

Dennis_Churaev [7]

Answer:

486kg

Step-by-step explanation:

density = mass / volume

2.7 = m / (100 x 60 x 30) **** Note the conversion to cm as the density is given in g/cm.

2.7 = m / 180000

m = 486000g

Now convert to mass in kg:

486000 g x 1 kg / 1000 g = 486kg
