Let the frequency be 'f' and wavelength be 'w'
,
w= 100 m and f = 3,000 kilohertz
Plug in the above values to find k
3000 =
To find k, multiply both side by 100
3000(100) = k
k = 300,000
So equation becomes,
w= ? f = 500 kilohertz
500 =
w =
w = 600 m
Answer:
Step-by-step explanation:
For finding the system of equations you can use one of two methods. There's the elimination method and also the substitution method. For this I think the best way we could go at solving this is by using the elimination method. Since we can eliminate the 2y. We can then solve for x and then we'll go from there.
Now that we know what x is we can substitute it for one of the equations and then we will be able to solve for y.
So now we have the x and the y and once we place them together we can get the solution of those two equations, and the solution is .
