First of all, I'm going to assume that we have a concave down parabola, because the stream of water is subjected to gravity.
If we need the vertex to be at
, the equation will contain a
term.
If we start with
we have a parabola, concave down, with vertex at
and a maximum of 0.
So, if we add 7, we will translate the function vertically up 7 units, so that the new maximum will be 
We have

Now we only have to fix the fact that this parabola doesn't land at
, because our parabola is too "narrow". We can work on that by multiplying the squared parenthesis by a certain coefficient: we want

such that:
Plugging these values gets us

As you can see in the attached figure, the parabola we get satisfies all the requests.
Answer:
I know this is not exactly what your looking for but if you make a line and put all the points from 4+3i to 6-2i then you can find the distance between them.
Step-by-step explanation:
I'm so sorry that I don't really know the answer
Pls forgive me
Answer:
-1/2
Step-by-step explanation:
Answer:
see the angle is more than 90 and it's obtuse in nature so u can find only supplement of that angle
85,106
The one with the U shape going up, and the red line is tilting to the left that last picture
