The time in hours it takes a satellite to complete an orbit around the earth varies directly as the radius of the orbit (from the center of the earth) and inversely as the orbital velocity. If a satellite completes an orbit 710 miles above the earth in 12 hours at a velocity of 22,000 mph, how long would it take a satellite to complete an orbit if it is at 1300 miles above the earth at a velocity of 30,000 mph? (Use 3960 miles as the radius of the earth.) Round your answer to the nearest hundredth of an hour. |
9.91 hours |

The amount of simple interest earned on an investment over a fixed amount of time is jointly proportional to the principle invested and the interest rate. A principle investment of $3200.00 with an interest rate of 5% earned $320.00 in simple interest. Find the amount of simple interest earned if the principle is $1800.00 and the interest rate is 2%. |
$72.00 |

Suppose that you have $3000 to invest. Which investment yields the greater return over 10 years: 8.75% compounded continuously or 8.9% compounded semiannually? |
$3000 invested at 8.75% compounded continuously over 10 years yields the greater return. |
