Answer:
AB=7.21 unit
BC=6 unit
CD=7.21 unit
AD= 6 unit
AC=4 unit
BD=4 unit
Step-by-step explanation:
Coordinates of A =(-2,3)
Coordinates of B = (2,-3)
Coordinates of C = (2,3)
Coordinates of D =(-2,-3)
Distance formula :
AB=7.21 unit
BC=6
CD=7.21
AD=6
AC=4
BD=
BD=4
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.
The difference in price per passenger for a group of 16 versus a group of 10 is $26.25
<h3>What is an equation?</h3>An equation is an expression that shows the relationship between two or more number and variables.
From the graph:
The cost for a group of 16 friends is $2500, while for a group of 10 friends is $1300.
Cost per passenger for 16 friend = $2500 / 16 = $156.25
Cost per passenger for 10 friend = $1300 / 10 = $130
The difference in price = $156.25 - $130 = $26.25
The difference in price per passenger for a group of 16 versus a group of 10 is $26.25
