Question:
The population of algebra was 34.9 million in 2009 and has been growing by about 2.6% each year. If this trend continues, when will the population exceed 45 million?
Exponential Growth:
Suppose that {eq}Q(t) {/eq} is some quantity that varies over time. We say that {eq}Q(t) {/eq} grows exponentially if there is some constant {eq}k > 1 {/eq} such that {eq}Q(t+1)=kQ(t) {/eq} for any {eq}t {/eq}. A quantity {eq}Q(t) {/eq} that grows exponentially in this way satisfies the equation {eq}Q(t)=Q(0)k^t {/eq}.
