those are the vertex form of a parabola... so hmmm
the vertex of this one is at 0,1 and intercepts or "solutions" are at -1 and 1, so is opening downwards, notice the picture below
that means, the squared variable is the "x", thus the form is

now, we know the vertex is at 0,1, and two x-intercepts of

thus

solve for "a", to see what that coefficient is, then plug it back in the vertex form equation
Answer:
0.256 or 0.26
Step-by-step explanation:
The common ration is being multiply by 0.4
Answer:
(2x² + 5x + 2) = (2x + 1)(x +2)
Step-by-step explanation:
Given expression is (2x² + 5x + 2).
We have to factorize the given expression.
(2x²+ 5x + 2) = 2x² + 4x + x + 2
= 2x(x + 2) + 1(x + 2)
= (2x + 1)(x + 2)
So the factored form of the given expression will be (2x + 1)(x + 2).
Ratio of Waitress to hostess money = 45/30 = 3/2
So, the ratio of waitress earning to total earning = 3/5
If they earn 350, waitress will receive = 350 * 3/5 = 210
So, your final answer is $210
Hope this helps!
dont now sorry i really wont to help
