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.

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

Answer:
Explanation:
A rectangle is a two-dimensional quadrilateral.
The area is given as:
Area of a rectangle = length x width
Perimeter = 2(L+ W)
where L is the length and W is the width
Condition:
If L and W are increased by 3 feet each;
New length = L + 3
New width = W + 3
Area of new rectangle;
Area = (L + 3) x (W + 3)
= LW + 3L + 3W + 9
Perimeter of new rectangle;
Perimeter = 2(L+3 + W + 3)
= 2(L+W +6)
