Write the prime factorization of 42

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?

Given ab and cb are tangents of p, and m =10°. what is the measure of abp?

Rationalize the denominator- 12x/√x-10
