Answer:
18 years ( approx )
Step-by-step explanation:
Since, if an amount is compounded daily,
Then, the final amount after t years is,
A= P(1 + r/365) 365t
Where, P is the principal amount
r is the annual rate ( in decimals ),
t is the number of years,
Given,
A = $ 800,
r = 3.9% = 0.039,
P = $ 400,
By substituting the values,
800= 400 (1 + 0.039/365)365t
t = 17.774 = 18
Hence, his balance will be $800 after approximately 18 years.
Answer:
(3x - 1)(x + 1)
Step-by-step explanation:
3x^2 factors into 3x and x.
-1 factors into -1 and 1.
Now we try different positions of 3x, x, -1, and 1 until we find the correct factorization.
Try: (3x - 1)(x + 1)
When you multiply the two factors together, the middle term will be 3x - x = 2x
Since 2x is the original middle term, this is the correct factorization.
Answer: (3x - 1)(x + 1)
