Answer:
A = 467.99
Step-by-step explanation:
A = 25.12 (8 + √49 + 64)
A = 25.12 (8 + √113)
A = 25.12 (8 + 10.63)
A = 25.12 (18.63)
A = 467.99
Answer:
I don't see anything
Step-by-step explanation:
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
<u>Answer:</u>
The correct answer option is D. 
<u>Step-by-step-explanation:</u>
We are given the following two functions:
and

We are to find
so we will subtract the function g from function f, arrange the like terms together and combine them like shown below to get:



Therefore,
is equal to
so the correct answer option is D.
