Answer:
y = 22.5
Step-by-step explanation:
Here, the 4 angles shown are all exterior angles of the polygon.
The sum of the exterior angles of a polygon is ALWAYS 360°
<em>So we add up the 4 angles (given in terms of y) and sum it to 360 and solve for y:</em>

y = 22.5
Answer:
The marginal cost at the given production level is $49.9.
Step-by-step explanation:
The marginal cost function is expressed as the first derivative of the total cost function with respect to quantity (x).
We have that the cost function is given by

So, we need the derivative and then we’ll need to compute the value x = 100 of the derivative.

When x = 100, the marginal cost is

Answer:
x ≤ -18. I hope this helps
