Question:

Catalytic converters are used in automobiles to convert harmful gaseous substances in the exhaust to more benign substances, for example, carbon monoxide to carbon dioxide. Beads used in these converters have extremely large surface areas. For instance, a single 3.0-mm porous bead can have a surface area of {eq}1.0 times 10^6; cm^2 {/eq}. If a car has two catalytic converters, each with {eq}5.0 times 10^3 {/eq} beads, calculate the surface area of the two catalytic converters in {eq}km^2 {/eq}.

To calculate the value of Cassandra's dresser after 3 years with an annual increase of 6%, we need to use the formula: V = P(1 + r/100)^n where P is the initial price of the dresser, r is the annual increase rate, n is the number of years, and V is the value of the dresser after n years. Plugging in the values we get: V = 500(1 + 6/100)^3 V = 500(1.06)^3 V = 590.82 Therefore, the value of Cassandra's antique dresser after 3 years with an annual increase of 6% will be \approx imately \$590.82.
