2th bounce- 80
5th Bounce- (-)200
9th Bounce- (-)560

Every time the ball bounces it loses 40cm because on the first bounce 160cm-120cm=40cm
And the score goes down by 40 every time and since we go into the negatives the negatives sometimes add on top of each other

Three friends were eating chocolate chip cookies after school. Nacy ate four less than two times the amount of cookies that Kate
galben [10]
Let the number of cookies that kate eats be ‘n’
kate : n
nacy : 2n-4
avery : 2(2n-4)

n + 2n-4 + 2(2n+4) = 18
7n - 12 = 16
7n = 28
n = 4

kate : 4
nacy : 2x4 - 4 = 4
avery : 2(2x4 - 4) =8

Use the parabola tool to graph the quadratic function f(x)=(x−2)(x−6) . Graph the parabola by first plotting its vertex and then
stepan [7]
Where's the so-called "parabola tool?"

The vertex is relatively easy to find.  Find the midpoint of the segment of the x-axis connecting x=2 and x=6; it is x=4.  Then evaluate the function at x=4:

f(4) = (4-2)(4-6) = 2(-2) = -4.  The vertex is at (4,-4).

Plot (4,-4).  Then (arbitrarily) let x=0 and find y:  f(0) = y = (-2)(-6) = -12.
So, when x = 0, y = -12.

Plot this point (1, -12).  realize that the parabola is symmetric about the line x=4.  (1,-12) is 3 units to the left of the axis of symm, and thus another point on the parab. is 3 units to the right of this axis, x= 7.  Plot (7,-12).  Now draw the parabola thru (7,-12), (1, -12) and (4, -4).  The parab. opens up.
