Answer:
The expression (1.09)x reveals the approximate rate at which the files are corrupted per minute.
Step-by-step explanation:
The number of files the virus corrupts doubles every 8 minutes.
The following expression represents the number of files corrupted after x minutes.
[tex]5(2)^ {\frac{x}{8}}[/tex]
[tex]5(2)^ {\frac{1}{8} \times x}[/tex]
[tex]5(1.09)^ x[/tex]
Thus The expression (1.09)x reveals the approximate rate at which the files are corrupted per minute.
Hence Option C is correct.
