Answer:
absolute value means a number's distance from 0
Step-by-step explanation:
Let's say you have -2 and you want the absolute value of it. -2 on a number line would be 2 places away from zero making it's absolute value 2. The absolute value of a number will never be negative either.

Quadrant one is the answer you should select.
The area of the square as a function of radius is given as A(r) = 2r^2
As given in the question a square is inscribed in a b. So the diagonals of the square will be the diameter of the circle.
The formula for the diagonals of the square is,
D = s√2
Where, s = side of the square
And the formula for the diameter of the circle is,
D = 2r
Where r = radius of the circle
As, Diagonals of the square = Diameter of the circle
Thus, s√2 = 2r
s = 2r/√2
s = r√2 (1)
Now, the formula of the area of the square is,
A = s^2
Putting the value of s from equation (1) in the above formula we get
A = (r√2)^2
A = 2r^2
Hence the area of the square as a function of radius is given as A(r) = 2r^2

Answer:
x^2 - x + 18
Step-by-step explanation:
f(x) = x^2+9
g(x) = x-9
Therefore f(x)-g(x),
= x^2 + 9 - (x - 9)
= x^2 + 9 - x +9
<h2>= x^2 - x + 18</h2><h2 /><h2 /><h2><u><em>
