Answer:

TRUST ME I KNOW!!!!

Explanation:

To determine how long it would take for $10,000 to double at a rate of 5.9%, we can use the concept of compound interest.

The formula for compound interest is:

A = P(1 + r/n)^(nt)

Where:

A is the final amount

P is the principal amount (the initial investment)

r is the annual interest rate (expressed as a decimal)

n is the number of times that interest is compounded per year

t is the number of years

In this case, we want to find the time it takes for the principal amount to double, so we can set A = 2P.

2P = P(1 + r/n)^(nt)

Dividing both sides by P:

2 = (1 + r/n)^(nt)

To isolate t, we can take the logarithm of both sides:

log(2) = log[(1 + r/n)^(nt)]

Using logarithmic properties, we can rewrite the equation as:

t = (log(2))/(n * log(1 + r/n))

Given a rate of 5.9% (0.059 as a decimal), we can substitute the values into the formula:

t = (log(2))/(n * log(1 + 0.059/n))

Since the compounding frequency is not provided in the question, we'll assume it's compounded annually (n = 1).

t = (log(2))/(1 * log(1 + 0.059/1))

Simplifying the equation:

t = (log(2))/(log(1.059))

Using a calculator, we can evaluate the expression:

t ≈ (0.693)/(0.056611)

t ≈ 12.22

Rounding to the nearest whole year, it would take approximately 12 years for $10,000 to double at a rate of 5.9%.
