The path of a ball kicked from the ground can be modeled by the equation y= -1/3 (x-3)(x-21). Where x and y are measured in feet. The x axis represents the ground. How far does the ball land from where it is kicked?

The ball lands ___ feet from where it is kicked. (Algebra 1)

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
