The average rate of change of credit card is $ 401.79 /year.

<h3>What is Average Rate?</h3>

A single rate that is a weighted average of the different rates that are applicable to property in various locations.
An average is a single number calculated as the average of a set of numbers, typically calculated as the sum of the numbers divided by the total number of numbers in the set (the arithmetic mean).

<u>Solution</u>

The difference of credit card debt between the year 2006 and 1992 = 8900 - 3275 = $5625

The difference of years between the year 2006 and 1992 = 2006 - 1992 = 14

average rate of change of credit card debt with respect to time = $\frac{difference of credit card debt}{difference of years}$

average rate = $\frac{5625}{14}$ = $ 401.79 / year

What is the approximate surface area of the sphere if circumference is 37.68?

damaskus [11]

The surface area of a sphere is A = 4 π R² .

Sadly, the question doesn't give you 'R', so you have to
back it out of the circumference.

   Circumference = π (diameter)

Divide each side by π : Diameter = circumference / π

Radius = 1/2 diameter: Radius = circumference / (2 π)

   Area = 4 π R² =

         4 π (circumference/2π)² =

   4 π (circumference)² / 4 π²

Divide top and bottom by 4π : Area = (Circumference)² / π

   Circumference = 37.68 units

   Area = (37.68)² square units /π =

   <em>451.93 square units</em>
