Answer: Time t = 33.0 seconds
Step-by-step explanation:
Given that the vertical distance H between the dock and the top of the boat's mast t seconds after its first peak is modeled by the function
H(t) = 5cos( 2π/3 t) − 35.5H
Where the maximum vertical distance = 5
At the down position, H(t) = 0
5cos( 2π/3 t) − (35.5/100)H = 0
5cos( 2π/3 t) − 0.355 × 5 =0
5cos( 2π/3 t) − 0.1775 = 0
5cos( 2π/3 t) = 0.1775
cos( 2π/3 t) = 0.1775/5
cos( 2π/3 t) = 0.355
2π/3 t = cos^-1 (0.355)
2π/3 t = 69.2
2πt = 69.2 × 3
2πt = 207.6
t = 207.6/2π
t = 33.0 seconds

Answer:
24 cugini
Step-by-step explanation:
6x2=12
12x2=24
convert yards to feet and minutes to seconds
1yard=3ft
16.8yards times 3ft/1yd=50.4ft
1minute=60 seconds
12minutes times 60seconds/1min=720seconds
feet per second=50.4ft/720sec=0.07ft/sec
answer is 0.07ft/sec
