z = 7√2 cos(7/8π) + 7√2i sin(7/8π) = 7√2e^(i7/8π)
Answer:
The function f(x) when x=x-4 is 
or 
Step-by-step explanation:
Given function f is defined by 
Now to find the function f(x-4):
Put x=x-4 in the above function we get
(using the formula 
)
(adding the like terms)
Therefore or
The function f(x) when x=x-4 is or

Answer:
3.93 (approx.)
Step-by-step explanation:
3 ^ x + 6 = 3 ^ 4 can be rewritten as 3 ^ x = 3 ^ 4 - 6, or
3^x = 81 - 6 = 75.
Then 3^x = 75, or
x*ln 3 = ln 75
Solving for x:
x = (ln 75) / (ln 3) = 3.93 (approx.)
