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) A) f(x) = -1 cos nx + 2
B) f(x) = -1 cos (x − n) + 2
C) f(x) = 2 cos (x - n) - 1
D) f(x) = 2 cos nx - 1

Ican interpret and represent the remainder in division calculations sensibly for the context (eg 27.4 in calculating average height in cm: $27.44 if it represents an amount of money) solve the following problems. 15) the wildlife park charges $25.50 dollars per person to enter their park if the park made $15096 dollars today, how many people entered the park? 16) ms adams plus 2,230 other keen runners ran a marathon: between them they ran 94817.5km. how many km did each competitor run?
