Answer:
8.5
Step-by-step explanation:
For continuous compounding, the account value formula is ...
A = Pe^(rt)
where P is the invested amount, r is the annual interest rate, and t is the number of years. We want to find t when ...
3550 = 2400e^(.046t)
ln(355/240) = 0.046t
t = ln(355/240)/0.046 ≈ 8.5
It will take 8.5 years for the value to reach $3550.

Answer:
Step-by-step explanation:
X^2 - 14 x = 15
(x - 7)^2 - 49 = 15
(x-7)^2 = 64
x - 7 = - or + 8
x = 15 or -1
Just take half o the coefficient of x and subtract it squared as above.
In general
x^2 + ax = b
(x + a/2)^2 - a^2/4 = b
