A rotating light is located 20 feet from a wall. The light completes one rotation every 3 seconds. Find the rate at which the li
ss7ja [257]

Answer:

43.17 ft/s

Step-by-step explanation:

Let the height of the wall is y.

distance of wall from light is 20 feet.

tan\theta =\frac{y}{20}    

y = 20 tanθ    .... (1)

time period, T = 3 second

\frac{d\theta}{dt}=\frac{2\pi}{3}

Differentiate equation (1) with respect to t.

\frac{dy}{dt}=20sec^{2}\theta\times \frac{d\theta}{dt}

\frac{dy}{dt}=20sec^{2}10\times \frac{2\pi}{3}

dy/dt = 20 x 2.16

dy/dt = 43.17 ft/s

Waves with an amplitude of 2 feet pass a dock every 30 seconds. Write an equation for a cosine function to model the height of a
kolbaska11 [484]

Answer:

The cosine function to model the height of a water particle above and below the mean water line is h = 2·cos((π/30)·t)

Step-by-step explanation:

The cosine function equation is given as follows h = d + a·cos(b(x - c))

Where:

\left | a \right | = Amplitude

2·π/b = The period

c = The phase shift

d = The vertical shift

h = Height of the function

x = The time duration of motion of the wave, t

The given data are;

The amplitude \left | a \right | = 2 feet

Time for the wave to pass the dock

The number of times the wave passes a point in each cycle = 2 times

Therefore;

The time for each complete cycle = 2 × 30 seconds  = 60 seconds

The time for each complete cycle = Period = 2·π/b = 60

b = π/30 =

Taking the phase shift as zero, (moving wave) and the vertical shift as zero (movement about the mean water line), we have

h = 0 + 2·cos(π/30(t - 0)) = 2·cos((π/30)·t)

The cosine function is h = 2·cos((π/30)·t).
