Find the final amount for a $750 investment at 5.25% interest compound semiannually for 25 years

=$2739.81

Step-by-step explanation:

To find the total amount if the interest is compounded, we use the compound interest formula.

A=P(1+R/100)ⁿ

A is the amount, P- principal, is the invested amount R is the % interest rate, n is the number if periods.

If compounded semi-annually, it means we have two periods in 1 year

The rate is also divided by 2

Thus 25 years have (25×2) = 50 periods.

A= 750(1+5.25/200)⁵⁰

=750(1.02625)⁵⁰

=$2739.81

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
