Step-by-step explanation:
Answer:
$843.74
Step-by-step explanation:
A = P (1 + r/n)^nt
A = 680(1 + 0.027/12)^12·8
A = 680( 1.00225)^96
A = 843.74
Answer:
B
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Given
(a + bi)(a - bi) ← expand using FOIL
= a² - abi + abi - b²i² → i² = - 1
= a² + b²
Since a and b are any real numbers, then
a² + b² is a real number
B
When a complex number is multiplied by its conjugate the result is always real.
