Narrowing it down it's either a or c because the other 2 choices open downward (negative a).
Graphing the 2 parabolas choice c is narrower.
c
Since it’s parallel, it should still be y2-y1/x2-x1 but answer is -12/3 which equals -4
A circle is the set of all points in a plane equidistant from a given point, as the mathematical definition holds. For a typical definition, you will take a point A and a specified distance r and the set of all the points at distance r from A is a circle.
Sorry I don't know I'm not that good at these kinds of things so so so sorry
Answer:
Step-by-step explanation:
5x12=60
(227.5x5x120)=13650
13650-9500=4150
apply formula
(2x12x4150)/((13650(60+1))=0.1196
0.1196x100=11.96% 0r 12%
