Simplify completly. 10 (t-5)^9/(4t+3) x (4t+3)-4(t-5)/(4t+3)^2
A population of bacteria is initially 4000. After four hours the population is 2000. If this rate of decay continues, which of these functions represents the size of the bacteria population after t hours
Select the correct answer below:
f(t)=4000(12)t4
f(t)=?4000(12)t
f(t)=4000(2)t4
f(t)=?4000(2)t
f(t)=4000(12)4t
