<span>P(x) = –x4 + x3 + 7x2 − x − 6
The graph will look like a bell, or a downward facing parabola, since the dominant term is -x^4
The graph has a y-intercept of -6, which can be considered the fixed cost (cost of zero trees cut) and moves upward from there, eventually reaching a maximum at some positive number of trees and dropping again. As x gets very large, profit becomes a very large negative number. Since we can't have negative trees cut, we're only interested in positive x values
The company breaks even at P(x) = 0
0 = </span> –x4 + x3 + 7x2 − x − 6, x greater than zero
0 = (x+2)(x+1)(x-1)(x-3)
The company breaks even at 1 tree and 3 trees.
Answer:
3
Step-by-step explanation:
The least number of trees planted is the least common multiple (LCM) of 3 and 10. Because 3 and 10 have no factors in common, that value is their product, 3·10 = 30.
If group B plants 30 trees, they will have planted 3 clusters.
Answer:
yes
Step-by-step explanation:
As an example
(x₁, y₁ ) = (1,2) and (x₂, y₂ ) = (5,3), then
d = = = =
Now let (x₁, y₁ ) = (5,3) and (x₂, y₂ ) = (1,2), then
d = = = =
Answer:
17.45
Step-by-step explanation:
6.98 / 0.4 = 17.45
