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
30.50-14= 16.50
16.50 divided by 2.75= 6
The answer is 6

$75 a month. 75x12 = 900. i used 12 because that’s the number of months in a year. hope this helps
2,317
Because you get 1,170 times .98 which equals 1,146.6. Then, you get 1,146.6 plus 1,170 and get 2,136.6 and to the nearest whole number it will be 2,317.
