The final amount in the account after 25 years is $24670.42.
<h3>
How do you calculate the final Amount after 25 Years?</h3>
Given that 3400 dollars are placed in an account with an annual interest rate of 8.25% for 25 years.
The final amount in the account is calculated by the formula given below.

Where A is the final amount, P is the initial principal balance, R is the interest rate, T is the time period.
The final amount is given below.



Hence we can conclude that the final amount in the account after 25 years is $24670.42.

Answer:
(x+1)^2 = 49
x = 6 x = -8
Step-by-step explanation:
x^2 + 2x – 48 = 0
Add 48 to each side
x^2 + 2x =48
Take the coefficient of x
2
Divide by 2
2/2=1
Square it
1^2 =1
x^2 + 2x +1=48+1
x^2 +2x+1 = 49
(x+1)^2 = 49
Take the square root of each side
sqrt((x+1)^2) =±sqrt( 49)
x+1 = ±7
Subtract 1 from each side
x+1-1 = -1 ±7
x = -1+7 x = -1 -7
x = 6 x = -8
Use the point-slope formula, y-y1=m(x-x1) to find the equation of the line
The answer is y=3x-1. Hope this helps!
