3.1 Lesson 4 #1. The population of cyanobacteria in a pond is modeled by the function below, with t representing hours. After approximately how many hours
will this population reach 30,000 cyanobacteria?
P = 17,500e^.017t

30000=17500e^0.017t

e^0.017t=1.76

㏑1.76=0.017t

0.56=0.017t

t=33hours

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
