Answer: Choice A. 1/64
Work Shown:
f(x) = 4^x
f(-3) = 4^(-3)
f(-3) = 1/(4^3) ... see note below
f(-3) = 1/64
Note: I'm using the rule that a^(-b) = 1/(a^b)
In equation form it would be the following:
2r + 3s = 13.
I believe.
Answer:
Step-by-step explanation:
So the answer would be
Basically plug in 2 where y is and 5 where X is
3(5)(2) - 4(2) , the parentheses are there to multiply
30-8
22
- 28 - 40i
note that i² = (√-1)² = - 1
expand product of factors using FOIL
= - 6 - 6i - 14i - 14i² - 20i + 36i²
= - 6 - 6i - 14i + 14 - 20i - 36
= - 28 - 40i
