2.18 that will be ur answer
Answer:
y = 2x^2 − 4x + 5
y = 2(x^2 − 2x) + 5
y = 2(x^2 − 2x + 1 - 1) + 5
y = 2(x^2 − 2x + 1) + 5 - 2
y = 2(x - 1)^2 + 3
x = 1 is the axis of symmetry.
Do you agree?
Lines a and b are parallel and cut by the same transversal, t. Since we know these lines are parallel, we can find the measure of angle 7 quite easily.
Angles 3 and 7 are corresponding angles, which means that the two angles are in the same relative position. Thus, they are equivalent.
Angle 3 = angle 7 = 120 degrees
The correct answer is C. 120.
Hope this helps!! :)
Pi * r^2 = 16.79
16.79/pi = 5.344.
r= 2.31
