Answer:
327.08 m/s
Step-by-step explanation:
Given that:
Length of pipe = 2.96m
4th harmonic frequency = 221 Hz
Speed of wave in the horn :
Speed of wave (v) = fλ
For 4th harmonic :
Wavelength, λ = (2/4)L
λ = L/2 ; 2λ = L
2λ = 2.96
λ = 2.96 / 2
λ = 1.48 m
Hence, speed of wave in the horn = 221 * 1.48 = 327.08 m/s
Answer: y = (1/8)x + 3.625
Step-by-step explanation:
slope: y = mx + b
change from 3 to 4 is 1, this is our rise
change from -5 to 3 is 8, this is our run
1/8 = m
this is a really bad explanation but I know that
1/8 is equal to 0.125.
since there are 5 spaces from (-5,3) to the y axis, and that the slope is 1/8, i can multiply 1/8 x 5 to get 5/8.
5/8 =.625
since the x intercept is in between 3 and 4, it is 3.625.
3.625 = b
Centimeters would suffice for measuring the length. I hope this helped! :)
I think the answer is 0.4
The blank space should be the common difference, or d. We can find that by what is being multiplied in the explicit, because it contains the common difference (at the end of the equation).
When looked at, d in the explicit formula is 4, so your answer would be 4.
