Answer:
Step-by-step explanation:
From the attached figure, AB is the height of the satellite and the distance between Ethan and the ground is 1 mile.
We can find the angle of elevation from Ethan to the satellite using trigonometry as follows :
So, the angle of elevation is 80.53 degrees.
The answer is y=-2/3+2 because the line crosses at 2, which is the y-intercept. It goes down two times and runs three times making the slope -2/3.
Answer; r=s+q-t —-> S=t-q+r
The wave length of the sound with parameters frequency of 125 Hz and a speed 5000 m/s is 40 meters
<h3>Given Data</h3>
velocity = 5000 m/s
frequency = 125 Hz
wavelength = ??
We know that the relationship between speed, frequency and wavelength is given as
v = fλ ----------------------------1
substitute our given parameters
5000 = 125 * λ
Divide both sides by 125
λ = 5000/125
λ = 40 m
Hence the wave length of the sound is 40 meters
