Step-by-step explanation:
Answer is 5 because 7-2 equals 5
well, one revolution is 2π radians, so 240 revolutions/min will just be
well, v = rω, and since we know ω from above, so
Since g(h(x))=h(g(x))= x, hence functions h and g are inverses of each other
Given the functions expressed as:
In order to check whether they are inverses of each other, we need to show that h(g(x)) = g(h(x))
Get the composite function h(g(x))
Get the composite function g(h(x))
Since g(h(x))=h(g(x))= x, hence functions h and g are inverses of each other
