Answer: 91%
Step-by-step explanation:
x = number of players on a team
Let's say we're talking about basketball. If each player makes a three-pointer (exactly one per player), then those players will earn 3x points overall. Now let's say the team already has 5 points to start with.
This would mean 3x+5 represents the current number of points.
8, 8, 8, 8, 8, 9, 9, 9, 9 would work as a sequence.
Median: 8
Mean: 8.4444....
The directrix x=-7 must be perpendicular to the axis that goes through the focus (7,0), then the axis of this parabola is y=0
The directrix cuts the axis of the parabola at the point (-7,0)
The vertex of the parabola V=(h,k) is the midpoint of the points (-7,0) and (7,0=
h=(-7+7)/2=(0)/2→h=0
k=(0+0)/2=(0)/2→k=0
Vertex: V=(h,k)→V=(0,0)
As the axis of the parabola is horizontal, the parabola has an equation of the form:
(y-k)^2=4p(x-h)
The parabola opens to the right then p is positive (p>0)
p is the distance between the vertex and the focus, the p=7
(y-k)^2=4p(x-h)
(y-0)^2=4(7)(x-0)
y^2=28x
Answer: <span>The equation of the parabola whose focus is at (7, 0) and directrix at x = -7 is: y^2=28x</span>
