B(1)=15 b(n)=b(n-1)•(-3) what is the 4th term in the sequence

Refer to interactive solution 17.45 to review a method by which this problem can be solved. the fundamental frequencies of two air columns are the same. column a is open at both ends, while column b is open at only one end. the length of column a is 0.504 m. what is the length of column b?

Explain how you do each step what term makes it inconsistent y=2x - 4 ?

Write the sine and cosine values of a, b, respectively, in the figure for (1) and (2) + explanation.
