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

Question 4

sleet_krkn [62]

Answer:

$\displaystyle about\:8\:units$

Step-by-step explanation:

Use the Distance Formula:

$\displaystyle \sqrt{[-x_1 + x_2]^2 + [-y_1 + y_2]^2} = D \\ \\ \sqrt{[6 - 1]^2 + [-7 + 1]^2} = \sqrt{5^2 + [-6]^2} = \sqrt{25 + 36} = \sqrt{61} ≈ 7,810249676 ≈ 8$

Since we are talking about distance, we ONLY want the NON-NEGATIVE root.

I am joyous to assist you anytime.
