Atrout population grew from 4 in 1992 to 16 in 1993 and then to 64 in 1994. if it continued to grow exponentially, approximately how many trout were there in 1995?
100
128
256

256

Explanation:

The exponential growth function of population is given by :-

, where A is the initial value ,b is the growth factor and t is the time period.

Since in the exponential growth ,the growth factor is the common ratio of the population in the  consecutive years.

Consider 1992 as the initial year , then A=4

and for 1995 , Time period x=3

Now, the number of trouts in year 1995 will be :-

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
