Part 1:
a = 2
b = 4
c = -3
Part 2: the parabola will open up
Part 3: axis of symmetry x = -1
Answer:
60?
Step-by-step explanation:
4000/200 = 20
20 × 3 =60
We are given the following measures:
mAB = 48°
mDC = 180°
In the given figure above, we can say that angle AVB is
an exterior angle which intercepts two arcs, arc AB and arc DC, therefore in
this case to solve for the measure of angle mAVB, we have to make use of the
formula which is in words:
Find the difference between the measures of the two
intercepted arcs and divide by 2, or expressed mathematically in this case as:
mAVB = (mDC – mAB) / 2
Substituting the given values into the equation:
mAVB = (180° - 48°) / 2
mAVB = 66°
