This corresponds to a sinusoidal graph, we have:
Radius= 20 feet, that corresponds to the amplitud (A)
One revolution takes 24 seconds, that corresponds to the period
Min= 3 feet
k=360/24=15
D= bottom distance+ amplitud=3+20=23 feet
Then, let x be the time, in seconds:
a) To determine Reid's height after 1 minute= 60 seconds, substitute x=60
b) To determine when Reid's height will first reach 18 feet, we have to substitute y=18 feet, and isolate x:
The answer would be A. -2
B because tangent is Opposite/hypotenuse. = 6/8 = 0.75
D when dividing, subtract the exponent on the bottom from the one on the top. a plain q has an exponent of 1.
To isolate g, divide both sides with -8.
240/-8= -30
g=-30
