45 minutes, because you run 1 mile in 8 minutes each. so 5 miles would be 45 minutes.
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
