Perform the indicated operation:
(4+2i)(1+5i)

(4+2i)(1+5i)= 22i-6

Step-by-step explanation:

Complex numbers are a combination of two parts i.e real and imaginary parts. The given operation is of multiplication.

Given

..

Function: C = 500 / n

Jane must recruit 20 more contributors or 25 contributors in total for the cost of each share to be $20.

Step-by-step explanation:

1. Cost per share, C, with respect to the number of contributors, n is

C = 500 / n

So, with 5 contributors, the price is $100 per share. $100 = 500/5

2. C= $20

20= 500 / n

20 * n = 500 * n

20n = 500

n= 25

She already has 5 contributors, so she needs 20 more.
