For complex number, the magnitude is pretty straight forward:
sqrt(6^2 + 2^2) = sqrt(40)
For any a + bi, the magnitude will be sqrt(a^2 + b^2)
Answer:
i dont khow
i guess true
Step-by-step explanation:
F(x) = 3x + 9
g(x) = 5x²
(f + g)(x) = (3x + 9) + 5x²
(f + g)(x) = 3x + 9 + 5x²
(f + g)(x) = 5x² + 3x + 9
Answer: 1.1%
Step-by-step explanation:
To get a percentage you want to divide the ending number by the base number
