A ferris wheel is 28 meters in diameter
and boarded from a platform that is 2
meters above the ground. The six
o'clock position on the ferris wheel is
level with the loading platform. The
wheel completes 1 full revolution in 4
minutes. The function h = f(t) gives
your height in meters above the
ground t minutes after the wheel
begins to turn.
What is the amplitude?
14
meters
What is the equation of the Midline?
y = 16
What is the period?
4
meters
minutes
The equation that models the height
of the ferris wheel after t minutes is:
f(t):
=
ƒ (3) = ·−14(0) + 16
syntax error: you gave an equation,
not an expression. syntax error. Check
your variables - you might be using an
incorrect one.
How high are you off of the ground
after 3 minutes? Round your answe
the nearest meter.
