Answer:
option A.) y-3 = 1/16 (x-2)^2
Step-by-step explanation:
we know that
If the axis of symmetry is parallel to the y-axis, then we have a vertical parabola
The equation of a vertical parabola is equal to
where
(h,k) is the vertex
In this problem we have
(h,k)=(2,3)
p=4
substitute

Answer:
B
Step-by-step explanation:
Given that ∠A ≅ ∠B, Evelia conjectured that ∠A and ∠B are acute angles.
Consider all options:
A. If m∠A=114° and m∠B=170°, then angles A and B are not congruent, so this is not a counterexample.
B. If m∠A=126° and m∠B=126°, then angles A and B are congruent and both these angles are obtuse (their measures are greater than 90°). This means that two obtuse angles can be congruent, so this is a counterexample. True option.
C. If m∠A=30° and m∠B=40°, then angles A and B are not congruent, so this is not a counterexample.
D. If m∠A=45° and m∠B=45°, then angles A and B are congruent, so this examples show two congruent acute angles. But if we have to prove some statement, we have to prove this statement for an arbitrary angles, not for one pair of angles. Moreover, this is an example illustrating given statement, but is not a counterexample.
An item, x, is marked up 40% and now costs $49.99
40% is 0.40
1 times any number will be the same number so we'll use that to add on the original price to the amount of increase
(1+0.40)x=49.99
x=49.99/1.4
x=35.71 so D is the answer
