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.

(x+9)(x+5)
Step-by-step explanation:
find 2 numbers that add to 14 and multiply to 45
Answer:
(5, 4 )
Step-by-step explanation:
Given the 2 equations
4x + 6y = 44 → (1)
4x + 2y = 28 → (2)
Subtracting (2) from (1) term by term eliminates the term in x, that is
(4x - 4x) + (6y - 2y) = (44 - 28), that is
4y = 16 ( divide both sides by 4 )
y = 4
Substitute y = 4 into either of the 2 equations and solve for x
Substituting y = 4 in (1)
4x + 6(4) = 44
4x + 24 = 44 ( subtract 24 from both sides )
4x = 20 ( divide both sides by 4 )
x = 5
Solution is (5, 4 )
