(x + 6) (x-2) (x-1)
Let's rewrite the expression step by step.
We have:
We multiply the first two parentheses:
(x ^ 2-2x + 6x-12) (x-1)
We rewrite:
(x ^ 2 + 4x-12) (x-1)
Now we multiply the remaining parentheses:
(x ^ 3 + 4x ^ 2-12x-x ^ 2-4x + 12)
We rewrite
(x ^ 3 + 3x ^ 2-16x + 12)
Answer:
The polynomial is:
(x ^ 3 + 3x ^ 2-16x + 12)

If 2.5 mol of dust particles were laid end to end along the equator, how many times would they encircle the planet? The circumfe

Natalka [10]

Answer:

They encircle the planet $3.76\times 10^{11}$ times.

Step-by-step explanation:

Consider the provided information.

We have 2.5 mole of dust particles and the Avogadro's number is $6.022\times 10^{23}$

Thus, the number of dust particles is:

$2.5\times 6.022\times 10^{23}=15.055\times 10^{23}$

Diameter of a dust particles is 10μm and the circumference of earth is 40,076 km.

Convert the measurement in meters.

Diameter: $10\mu m\times \frac{10^{-6}m}{\mu m} =10^{-5}m$

If we line up the particles the distance they could cover is:

$15.055\times 10^{23}\times 10^{-5}=15.055\times 10^{18}=1.5055\times 10^{19}$

Circumference in meters:

$40,076km\times \frac{1000m}{1km}=40,076,000 m$

Therefore,

$\frac{1.5055\times 10^{19}}{40,076,000} = 3.76\times 10^{11}$

Hence, they encircle the planet $3.76\times 10^{11}$ times.

Hunter-Best [27]

The samples he chose may not be a representative sample because the number of students per foreign language class may not be the same. One class may have a very large number of students while another may have only a few. Taking equal number of students per class is not a representative sample.
