Use the graph below to answer the question that follows:
cosine graph with points at 0, 1 and pi over 2, negative 5, and pi, 1
what are the amplitude, period, and midline of the function?
amplitude: 6; period: 2π; midline: y = −3
amplitude: 6; period: π; midline: y = −3
amplitude: 3; period: π; midline: y = −2
amplitude: 3; period: 2π; midline: y = −2

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
