First, find the measure of an interior angle: the sum of the interior angles of a polygon is (n-2)*180, n is the number of sides for a 15-sided polygon, the sum is 13*180 each interior angle is then 13*180/15=156 the measure of each exterior angle=180-156=24
This is the concept of exponential growth, To get the number of bacteria after 10 days we use the formula: f(t)=ae^(kt) where; a=initial number=5000 k=constant of proportionality= 0.04 t=time=10 days f(t)=future number thus the number of bacteria in 10 days will be: f(t)=5000e^(0.04*10) f(t)=7,459.12 The answer is 7,459.12
