A person inventes 4500 dollars in a bank. The bank pays 4.75% interest compounded semi-annually. To the nearest tenth of a year, how long mist the person leave the money in the bank until it reaches 5900 dollars

It should take 5.8 years to reach his goal.

Step-by-step explanation:

In order to solve this question we must use the compounded interest's formula shown below:

M = C*(1 + r/n)^(t*n)

Where M is the final amount, C is the initial amount, r is the interest rate, n is the compound rate and t is the time elapsed in years. Applying the data from the problem we have:

5900 = 4500*(1 + 0.0475/2)^(2*t)

5900 = 4500*(1 + 0.02375)^(2*t)

5900 = 4500*(1.02375)^(2*t)

4500*(1.02375)^(2*t) = 5900

(1.02375)^(2*t) = 5900/4500

(1.02375)^(2*t) = 59/45

log[1.02375^(2*t)] = log(59/45)

2*t*log(1.02375) = log(59/45)

t = log(59/45)/[2*log(1.02375)] = 5.77008

It should take 5.8 years to reach his goal.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
