1.
the line of symmetry is x=2, means that the x coordinate of the vertex is x=2.
the point x=2 is the midpoint of the roots
and
.
so
Remark: in the x-axis, if c is the midpoint of a and b, then
2.
since
and
are roots
and
3.
equalizing:
in the left side factorize a, in the left side factorize 8:
in the right side use the difference of squares formula:
simplify by
substitute
with 4:
a=2
Answer: C)2
No, because there is not enough information given to make a conclusion. Providing a percentage of 46% higher profit per acre doesn't mean statistical significance as it could be data-based only. There should be a given p value to make a conclusion about statistical significance.
Answer: So rounding 69581.491337 to the nearest thousand is
70000
x + (x + 2) + (x + 4) = 384
2x + 2 + (x + 4) = 384
3x + 6 = 384
3x = 378
x = 126
The answer is 126.
