Answer:
the answer is in the picture with process
f(x) = x + 1/x
f(1 + 3i), lets just sub x by 1 + 3i
f(1 + 3i) = 1 + 3i + 1/(1 + 3i)
Doing the sum (1 + 3i) + 1/(1 + 3i) we get ((1 + 3i)² + 1)/(1 + 3i)
So:
f(1 + 3i) = (1 + 2.1.3i + 9i² + 1)/(1 + 3i)
f(1 + 3i) = (6i - 7)/(1 + 3i)
f(1 + 3i) = 11/10 + 27i/10
Answer:

Step-by-step explanation:
120/20 = 6
200/20= 10
Answer:
20%
Step-by-step explanation:
First, find the difference between $130 and $104. This equals $26, and to find this discount written as a percent, divide $26 by the original cost of the camera. 26/130=0.2, which represents a 20% discount.
