Answer:
-19
Step-by-step explanation:
Answer:
If using simple interest, the formula is:
= Amount * ( 1 + rate * time)
= 20,000 * ( 1 + 4% * 5)
= $24,000
Interest = Balance after 5 years - Investment
= 24,000 - 20,000
= $4,000
Using Compound Interest:
= Amount * ( 1 + rate)^time
= 20,000 * ( 1 + 4%)⁵
= $24,333.06
Interest = 24,333.06 - 20,000
= $4,333.06
√8 = √(4x2) = 2√2
4√2 =4√2
2√2-4√2 = -2√2
D because some of the inputs have the same output therefor it is not a function
