(8r+3s)(8r-3s) dont have working but noticed that it is the difference of two squares
The equation of a circle is defined by:
(x-h)^2+(y-k)^2=r^2
Where (h,k) s the center and r is the radius.
We can translate the word problem into (x+2)^2+(y-8)^2=16

Step-by-step explanation:
Answer:
2 - 2y^2 - x/y
Step-by-step explanation:
2x^2/x^2 = 2
and
x^2/xy = x/y
therefore
2x^2/x^2 - y^2 - x^2/xy - y^2
= 2 - y^2 - x/y - y^2
= 2 - y^2 - y^2 - x/y
= 2 - 2y^2 - x/y
Answer:
The height of the surface increases, then decreases, from the center out to the sides of the road.
Step-by-step explanation:
Let
y------> the height of the surface
x------> the road
we know that
The quadratic regression graphed represent a vertical parabola open downward
The function increase in the interval -------->
The function decrease in the interval --------> ![(0,5]](https://tex.z-dn.net/?f=%280%2C5%5D)
therefore
The height of the surface increases, then decreases, from the center out to the sides of the road.
