Hey! Sorry for the 6 day late response. The answer is:
25%
From calculus, to determine the maxima or minima of the graph, get the derivative of the equation and equate to zero. So, we derive first the equation of the graph and equate to zero.
C = 0.25x² - 80x + 30000
dC/dx = 0 = 0.5x - 80 + 0
0.5x = 80
x = 80/0.5
x = 160 units
The minimum cost (although not asked) is:
C = 0.25(160)² - 80(160) + 30000
C = $23,600
The answer is 160 units.
Male 0.271 0.198
Female 0.229 0.302
I think that's right because that's what my quiz said
Answer:
Graph 2
Step-by-step explanation:
Graph two is not a function because it does not pass "the vertical line test", which is a method of determining if a graph is a function or not. To do this, we use our pen to check that for every x value there is only one y value. In graph two, however, this is not the case.
Answer:
h = -7
Step-by-step explanation:
- 3 = h + 4
- 3 - h = 4
- h = 4 + 3
- h = 7
