Answer:
0.08333333333
Step-by-step explanation:
because 1/3 divided by 4 equals 0.08333333333
The formula for the axis of symmetry (AOS) is -b/2a.
The 'a' and 'b' values can be derived from examining the standard form of the quadratic,
ax^2+bx+c
In this scenario,
a=5
b=40
Now plug in the values.
-b/2a
-40/2(5)
-40/10
-4
Remember that "-4" is not your answer. Since the AOS is a vertical line of symmetry of any even degree polynomial, your answer would be<u> </u><u>x = - 4

part A)
we know that for every 1000 ft the temperature drops by 1.3.
so after 1000ft up it went down by 1.3(1)
2000ft up it went down by 1.3(2) or 2.6
3000ft up it went down by 1.3(3) or 3.9
after 10000 up it went down by 1.3(10) or 13.
part B)
well, the current temperature on the ground where the plane is sitting is -2.8°F, after 10000ft it dropped by 13°, so the temperature will just be -2.8 - 13 = -15.8°F.
The value of x = 10
12x - 10 = 10x + 10
2x = 20
x = 10
