Answer:
Step-by-step explanation:
v=d/t, t=d/v, since t=t
1225/(v+w)=1100/(v-w)
1225v-1225w=1100v+1100w
2325w=125v
w=125v/2325, given v=575
w=125(575)/2325
w=30.91 mph
Answer:
The inverse of g(x) is
The domain of g(x) is (-∞,-2)U(-2,∞)
The domain of f(x) is (-∞,-1)U(-1,1)U(1,∞)
Step-by-step explanation:
Find the inverse of g(x).
Solve for x
Find the domain of g(x)
Numerator and denominator have domain
(-∞,∞).
However, g(x) is undefined if the denominator is 0. Hence, x=-2 must be taken out of the domain. So, the domain of g(x) is
(-∞,-2)U(-2,∞).
Find the domain of f(x)
The numerator and denominator have the domain
(-∞,∞)
However, f(x) is undefined if the denominator is 0. This rules out +1 and -1. So, the domain of f(x) is
(-∞,-1)U(-1,1)U(1,∞)
I am not sure what you mean for (ii).
