  • Are you told the diameter of the water wheel? Without it, we can find everything except the maximum height above the water. I will finish everything with a variable of M as the maximum distance above the water. 6 revolutions / minute = 6 revolu…
  • The domain of f(x) is the domain of y=lnx, which is x>0. Using product rule, f '(x) = 7 - 2lnx - 2 = 5 - 2lnx. Set f '(x) equal to 0 to find any critical values: 5 - 2lnx = 0 lnx = 2.5 x = e^2.5 ≈ 12.1825 Since f'(x) > 0 on the interval (…
  • Unit rate means you want the time unit to be 1. So you would divide each measure by 3 to get 50 miles / 1 hour or more conveniently stated, 50 mph
