If you deposit $8000 into an account paying 9% annual interest compounded semi-
annually, how long will it take for your money to double? Round to the nearest
hundredth.

n=7.87 years

Step-by-step explanation:

- The principal amount of $8000 doubles to become $16000.

-Given the rate is 9% compounded semi-annually, we first determine the effective rate:

We use this rate to in the compound interest formula to solve for n:

Hence, it takes 7.87 years for the amount to double to $16,000

the answers c

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
