The sum of two equal sinusoids are equal to each other.

Answer:

The only way the sum of two sinusoids is a sinusoid is if the two sinusiods have the same period.

Lets assume that one sinusoid is A and the other is B, the sum of the two is C:

A and B must both have the same period to get another sinusoid (C).

C can only be a sinusoid if A and B (both sinusoids) have the same periods.

Maru [420]

Answer:

20 represent the cost per variable inputs

Step-by-step explanation:

C(x) = 20(4x) + 500

Total cost is the addition of variable cost and fixed cost

Fixed cost are cost that do not change during the production process such as machinery, furnitures and fittings.

Variable cost are cost of production that changes with production process such as cost of labor, cost of raw materials.

C(x) = 20(4x) + 500

20(4x) represent the variable cost

500 represent the fixed cost

From the variable cost 20(4x)

20 represent the cost per variable inputs
