very quickly #5. The world's fastest roller coaster is at Six Flags Magic Mountain. At the start, riders are shot forward and then up
a tower. They then begin the backward descent. The cars reach speed of 160 km/h in 7 seconds during the descent.
From a point 100 metres from the foot of the tower, the angle of elevation to the top of the tower is 52º. Find the height of the tower, to the nearest metre.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
