Answer:
Step-by-step explanation:
Solve the Function Operation
Rewrite
=
so is on the left side.
=
2 1/3 x 4/5
Rewrite 2 1/3 as 7/3
7/3 x 4/5 = (7 x 4) / (3 x 5) = 28/15 = 1 13/15
D) 5 is the answer
Assuming AE and CE are the same length you would set the two equations to each other: 8x+7=11x-8
Then solve for x:
Subtract 8x from both sides and add 8 to both sides looking like: 15=3x
Divide by 3 to get x by itself and you get x =5
Answer:
Answer:
Speed of the wave in the string will be 3.2 m/sec
Explanation:
We have given frequency in the string fixed at both ends is 80 Hz
Distance between adjacent antipodes is 20 cm
We know that distance between two adjacent anti nodes is equal to half of the wavelength
So \frac{\lambda }{2}=20cm
2
λ
=20cm
\lambda =40cmλ=40cm
We have to find the speed of the wave in the string
Speed is equal to v=\lambda f=0.04\times 80=3.2m/secv=λf=0.04×80=3.2m/sec
So speed of the wave in the string will be 3.2 m/sec
