Answer:
x = ---------- = 1
Step-by-step explanation:
The formula for the axis of symmetry is x = -b/(2a). In this case b = -4 and a = 2, and so the axis of symmetry is
-(-4)
x = ---------- = 1
2(2)
We have been given that Circle C has diameter AE with a length of 2 cm, and a central angle with the measure . We are asked to find the length of arc DE.
We will use arc length formula to solve our given problem.
, where,
= Arc length,
= Central angle in degrees.
r = radius of circle.
Since AE is diameter, so radius will be half of AE.
Upon rounding to nearest tenth, we will get:
Therefore, the length of arc DE is approximately 0.7 cm.

Finding a common denominator between 10 and 12 to be 10*12=120, we can multiply 9/10 by 12/12 and 3/12 by 10/10 to get 108/120 and 30/120 respectively. Dividing the 2 (as we want to know how much 3/12 or 30/120 goes into 9/10 or 108/120), we get
(108/120)/(30/120)=(108/120)*(120/30)=(108/30)=3+18/30 (as 30 goes into 90 3 times and 108-90=18)
