Jamie kicked a soccer ball that traveled along a path described by the parabola y = -x^2 +8x, where y equals the height of the s
2 answers:
Equation of any Parabola is of the form y=
If a is negative the parabola opens down.
The given equation of soccer ball that traveled along a path was y=
Comparing the two equations we have a=-1,b=8
As a is negative the parabola opens down and will have the maximum point at vertex .
The x of vertex is given by x=
Substituting a and b values we have:
x=
The y of vertex is y=
The highest point the soccer ball hit the ground is 16 ft.

<span>Scientific notation is the way that scientists easily handle very large numbers or very small numbers. Scientific notation is written by writting a decimal number between 1 and 10 together with an exponent of 10.
Given
First, using distributive property of numbers, seperate the decimal numbers and the exponents of 10, we have
Because, scientific notation requires that the decimal number part be a number between 1 and 10, we move the decimal point 1 place foward and subtract 1 from the exponent of 10.
Therefore, </span><span>
