Answer:
a(n)=6*2^(n-1)
Step-by-step explanation:
a(n)=a(1)r^(n-1)
a(1) = 6
a(2)=6r^1=12
r=2
a(n)=6*2^(n-1)

<h3><u>given</u>:</h3>
wave length= 0.5 m
frequency= 2134 Hz
<h3><u>to find</u>:</h3>
the speed
<h3><u>solution</u>:</h3>






<u>hence</u><u>,</u><u> </u><u>the</u><u> </u><u>speed</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>wave</u><u> </u><u>is</u><u> </u><u>1067s</u><u>.</u>
Take into account that x represents the number of decades after 1950. Moreover, consider that -0.5x is a decrease in the values of y, each decade.
Then, you can conclude that each decade, that is, every 10 years, the shoreline reduces 0.5 feet.
Hnece, you have:
The shoreline is reduced by 0.5 foot every 10 years
