All are correct
the equation of a given progressive wave is
y=5sin(100πt−0.4πx) ......(i)
The standard equation of a progressive wave is
y=asin(ωt−Kx) ...(ii)
Comparing (i) and (ii), we get
a=5m,ω=100π rad s
−1
,k=o.4πm
−1

Answer:
30th term of the sequence is -19
Step-by-step explanation:
first term = 10
common difference = 9- 10 = -1
so, nth term = a + (n-1) d
( where n is number of term, a = first term ,
d = common difference. )
- 30th term = 10 + (30-1) × -1
- 30th term = 10 - 29
- 30th term = -19
