Answer:
x^2 + y^2 <= 4, 0 <= z <= 8
Step-by-step explanation:
- Region that lies on/below the plane means Z<=8
- Region that lies on/above the xy plane means Z>=0.
Combining 1 and 2, we get
0<=Z<=8
If we want disk of radius 2 in x-y plane to be centered at origin the inequality becomes:
x^2 + y^2 <= 4
Her expenses are a fixed expense of $4500 and a weekly expense of $200.
Let's call the unknown number of weeks w.
In w weeks, the weekly expenses will by 200w.
The total expense is
200w + 4500
In a week, when earns $550. In w weeks, she earns 550w.
Set the expenses equal to the earnings and solve for w.
550w = 200w + 4500
Subtract 200w from both sides.
350w = 4500
w = 12.86
It takes her 12.86 weeks to break even.
If she works 13 weeks, she begins to make a profit.
