Answer:

(f∘f)(x) = x⁴ -12x² +30

(g∘g)(x) = x/9

Step-by-step explanation:

a) (f∘f)(x) = f(f(x)) = f(x² -6)

... = (x² -6)² -6

... = x⁴ -12x² +36 -6

... (f∘f)(x) = x⁴ -12x² +30

b) (g∘g)(x) = g(g(x)) = g(x/3)

... = (x/3)/3

... (g∘g)(x) = x/9

The circumfrence is 16 pi. What is the are in terms of pi?
Liono4ka [1.6K]
\bf \textit{circumference of a circle}\\\\
C=2\pi r~ 
\begin{cases}
r=radius\\
-----\\
C=16\pi 
\end{cases}\implies 16\pi =2\pi r\implies \cfrac{16\pi }{2\pi }=r\implies \boxed{8=r}\\\\
-------------------------------\\\\
\textit{area of a circle}\\\\
A=\pi r^2\qquad \qquad \qquad \implies A=\pi (8)^2\implies A=64\pi

Which graph correctly represents x + 2y ≤ 4?
blagie [28]
If you put the formula into Y intercept form which is Y=M(slop)X + B(y int)

you will get
y = -1/2x + 2
B(y int) = 2
M(slope) = -1/2

plot (0,2) on graph then go down 1 left 2. put a point there repeat and connect dots.
