YES

We know: $(a^n)^m=a^{n\cdot m}$

We have: $x^6=x^{2\cdot3}=(x^2)^3$

Researchers at the Centers for Disease Control and Prevention have been studying the decay pattern of a new virus with a decay r

Andrei [34K]

Answer:

They will find 69 viruses in 8 hours.

Step-by-step explanation:

The number of viruses after t hours is given by the following equation:

$V(t) = V(0)(1-r)^{t}$

In which V(0) is the initial number of viruses and r is the decay rate, as a decimal.

They start with 500 viruses

This means that $V(0) = 500$

Decay rate of 22% per hour.

This means that $r = 0.22$

$V(t) = V(0)(1-r)^{t}$

$V(t) = 500(1-0.22)^{t}$

$V(t) = 500(0.78)^{t}$

How many viruses will they find in 8 hours?

This is V(8).

$V(t) = 500(0.78)^{t}$

$V(8) = 500(0.78)^{8}$

$V(8) = 68.51$

Rounding to the nearest whole number

They will find 69 viruses in 8 hours.
