Answer:
2070m/s
Step-by-step explanation:
frequency=900HZ
Wavelength=2.3m
now,
speed of wave= frequency × wavelength =900×2.3
=2070m/s

Answer:
4.138138=469069/500000
Step-by-step explanation:
-10. One type of system of equations that results in infinite solutions is one where both sides of the equation are exactly equal. Here, setting the second equation equal to -10 becomes 2y - 4x = -10. This can be rearranged into 2y = 4x - 10. Dividing everything by 2 results in y = 2x - 5, which is exactly what the first equation is. Substituting one equation into another, we get 2x - 5 = 2x - 5, which is a true statement for all values of x.
