Answer:
0.128rad/sec
Step-by-step explanation:
Let x represent the between the man and the point on the path
θ = the angle
dx/dt = 4 ft/s
dθ/dt = rate is the searchlight rotating when the man is 15 ft from the point on the path closest to the searchlight
tan θ = x/20 ft
Cross Multiply
20tan θ = x
dx/dt = 20sec² θ dθ/dt
dθ/dt = 1/20 × cos² θ dx/dt
dθ/dt= 1/20 × cos² θ × 4
dθ/dt = 1/5 × cos² θ
Note : cos θ = 4/5
dθ/dt = 1/5 × (4/5)²
dθ/dt = 16/125
dθ/dt = 0.128rad/sec
10+55= 05 Carry the 1 so 11+2+1= 14= 2
So your answer is 2:05. If you were doing am, it would be 205 pm and vice versa

HOPE ITS RIGHT LOL
Solving equations is a basic skill that you must master to deal with a
lot of problems in mathematics, physics, chemistry, administration,
economy, and almost every activity where you need to use a formula or a
model. to solve for h, you follow these steps: 1) multiply both sides by
2 => 2A = (a+b)h; 2) divide both sides by (b+a) => 2A/ (a+b) = h.
So the answer is: h = 2A / (a+b).
