Roots = 2, 4
A.O.S = 3.
The zeroes are where the parabola will meet the x-axis. The axis of symmetry pretty much just splits your parabola equally in half.
Given:
A diagram of a circle O, 
.
To find:
The measure of arc DC.
Solution:
According to the angle of intersecting chords theorem:
Angle at intersection of chords = Half of the sum of intercepted arcs.
Let 
be the angle between the intersection of chords AC and BD.
(Linear pair)
Using the angle of intersecting chords theorem, we get
On simplification, we get
Divide both sides by 2.
Now,
Therefore, the correct option is C.
Im going to keep it simple, the answer is 9
<span> 16ft long shadow of a building when the building true height is</span> 40 ft
1 ft long shadow of a building when the building true height is <span>40/16 ft
</span>2 ft long shadow of a person when the building true height is <span>(40x2)/16 = 5ft (ans)
