Answer:
a is 25 b is 15 percent
Step-by-step explanation:
the sequence starts at 10 and increases by 7 each time, thefore a possible sequence identification is:
Therefore, the 100th term is:
To simplify 4/(2+7i), we multiply it by a fraction equal to one that removes the i value in the denominator. The best value to do this is the complex conjugate divided by itself, so we have 4(2-7i)/((2+7i)(2-7i)). Simplifying, we have (8-28i)/(4-(-49))=(8-28i)/53, which is a completely simplified fraction since 8 and 53 are relatively prime (or coprime), and there are no radicals in the denominator.
