Derive an equation d = acos(bt) for the displacement d (in feet) in relation to sea level of a piece of cloth tied to a water wheel over t seconds. assume the water wheel is half-submerged and takes 24 seconds to complete one turn. at t = 0 seconds, the cloth is at a height of 10 feet above sea level, its maximum displacement from the surface of the water. find the values of a and b.

Step-by-step explanation:

a=10

b=pi/12

d=10cos(pi/12t)

t=6

d=5

a=10

b=pi/12

d=10cos(pi/12t)

t=6

d=5

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
