Answer:
b. 15 square units
Step-by-step explanation:
We notice from the graph that AB is the hypotenuse of a right triangle 3 units wide and 6 units high. The Pythagorean theorem tells you the length of that will be ...
AB = √(3^2 +6^2) = √45 = 3√5
Similarly, altitude CD is the hypotenuse of a right triangle 4 units wide and 2 units high, so its length will be ...
CD = √(4^2 +2^2) = √20 = 2√5
The area is given by the formula ...
A = 1/2bh
A = 1/2(3√5)(2√5) = 15 . . . square units
<span> For this case we have the following equation:
</span>
<span> Where,
x: number of chips
c (x): total cost
To find the fixed cost, we must find the intersection with the y axis of the given equation.
So we have that for x = 0:
</span>
<span>
Therefore, the fixed production cost is given by:
</span>
<span> Answer:
The fixed cost of producing the chips is:
c (0) = 12000</span>
