What cosine function represents an amplitude of 2, a period of 2n, a horizontal shift of n, and a vertical shift of -1? (6 points) f(x) = -1 cos nx + 2
f(x) = -1 cos (x - n) + 2
f(x) = 2 cos (x - n) - 1
f(x) = 2 cos nx - 1

When they are both racing on hoverboards, victoria is 3 times as fast as her brother max. when she is on foot, she is 3 times slower than max on his hoverboard. they took off on hoverboards at the same time, but after 12 minutes, victoria’s hoverboard broke and she immediately started to run. if the race was a tie, how long, in minutes, did it last from start to finish?
