Tracy invests 500 into an ETF which earns 8% per year. In 5years how much will Tracy’s investment be worth if interest is compounded semiannually (twice a year)? Round to the nearest dollar

$740

Step-by-step explanation:

(see attached picture for reference)

I'm going to assume that when you wrote "500", you mean "$500"

recall that the formula for compound interest:

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

where

P = principal amount = $500

r = interest rate = 8% = 0.08

n = number of times compounded in a year = 2 (note: semi-annually means twice a year, hence n = 2)

t = number of years = 5

substituting this into the equation,

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

A=500 [ 1+(0.08/2) ] ^ (2 x 5)

A= $740.1221

A = $740 (rounded to nearest dollar)

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
