Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More precisely, one light-year is equal to 9,500,000,000,000 kilometers.

A bacteria population decreases by a factor of 1/2 every 4 hours. Explain why we could also say that the population decays by a

kirza4 [7]

The population decays by a factor of (1/2 )^1/4 every hour.

<h3>Exponential Function</h3>

An exponential function is in the form:

y = abˣ

Where a is the initial value of y, b is the multiplier, y and x are variables.

Let y represent the bacteria population after x hours.

A bacteria population decreases by a factor of 1/2 every 4 hours.

$y=\frac{1}{2} ^\frac{x}{4}= \frac{1}{2} ^{(\frac{1}{4})x}$

The population decays by a factor of (1/2 )^1/4 every hour.
