Answer:
218.93 km
Explanation:
= Angle between the paths of the two boats = 54.10°
Distance = Speed × Time
Distance traveled by one boat =
Distance traveled by other boat =
From the triangle law of vectors we have
The distance they will be apart after 3 hours is 218.93 km
Answer:
there are 2188 people at the game
Explanation:
Given the data in the question;
we know that decibel is defined as; dB = 10log(l/l₀)
so if one produces an intensity l₁, it results in 69.6 dB
69.6 = 10log(l₁/l₀) ---- equ1
also. if x number of people produces this intensity, it result to 103 dB
103 = 10log(xl₁/l₀)
103 = 10( log(l₁/l₀) + log(x) )
103 = 10log(l₁/l₀) + 10log(x) ----- equ2
input equation 1 into to equation 2
103 = 69.6 + 10log(x)
10log(x) = 103 - 69.6
10log(x) = 33.4
divide both side by 10
log(x) = 3.34
x =
x = 2187.76 ≈ 2188
Therefore, there are 2188 people at the game
