6 0

Answer:

720 Arrangements

Step-by-step explanation:

Given the numbers could be from 0 - 9 and none of them is to be repeated.

The first place could be filled in 10 ways. (0 - 9)

The second place could be filled in 9 ways. (Excluding the one in the first place).

The third place could be filled in 8 ways. (Excluding the two numbers in the first two places).

Therefore, the total number of arrangements possible for the lock is: $10 \times 9 \times 8$ = 720 ways.

Nat2105 [25]

Answer:

The total profit P(x) or the month is $P(x)=-0.5x^2+500x-350$ .

Step-by-step explanation:

A company produces x units of a product per month.

The total cost represents by the function C(x).

$C(x)=300x+250$

The total revenue represents by the function R(x).

$R(x)=-0.5x^2+800x-100$

The profit is the difference between revenue and cost.

$P(x)=R(x)-C(x)$

$P(x)=-0.5x^2+800x-100-(300x+250)$

$P(x)=-0.5x^2+800x-100-300x-250$

Combine like terms.

$P(x)=-0.5x^2+(800x-300x)+(-100-250)$

$P(x)=-0.5x^2+500x-350$

Therefore, the total profit P(x) or the month is $P(x)=-0.5x^2+500x-350$ .

Given that:

A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area) is proportional to the quantity it represents.

The pieces of the graph are proportional to the fraction of the whole in each category.

Each slice of the pie is relative to the size of that category in the group as a whole.
