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

What’s 25 x s =300 what’s the equation
Aliun [14]
If I get this it should be, 25 x 12 = 300, think it as 4 x 25 is 100 so you need 3 x 100, so 4 x 3 is 12, 25 x 12 =12, hope this helps
