Abook sold 39,400 copies in its first month of release. suppose this represents 8.9% of the number of copies sold to date. how many copies have been sold to date?

The book has sold 442,696 copies to date. This was calculated by making a proportion: 8.9 : 39,400 = 100 : X where X Is the number of copies sold. Then I calculated 39,400*100/8.9 to obtain the answer

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
