A ball bounces to a height of 6.1 feet on the first bounce. Each subsequent bounce reaches a height that is 82% of the previous bounce. What is the height, in feet, of the fifth bounce? Round your answer to the thousandths place.

Respuesta :

In the first bounce, the height is

[tex]6.1\times(0.82)^0=6.1[/tex]

In the second bounce, the height is

[tex]6.1\times(0.82)^2=5.002[/tex]

Then, we can note that the pattern is

[tex]6.1\times(0.82)^{n-1}[/tex]

where n represents the number of bounces of the ball. Then, for n=5 (fifth bounce), we get

[tex]\begin{gathered} 6.1\times(0.82)^{5-1} \\ 6.1\times(0.82)^4 \end{gathered}[/tex]

which gives

[tex]6.1\times(0.82)^4=2.7579[/tex]

Therefore, by rounding to the nearest thousandths, the answer is 2.758 feet
