The population of a city is 270,000 and is increasing at a rate of 2.25% each year. approximately when will the population reach 540,000?

The population will reach 540 000 in 30.8 yr.

The formula for population growth is

P_t = P_0 × e^(rt)

540 000 = 270 000 × e^(0.0225t)

e^(0.0225t) = 2

0.0225t = ln2

t = (ln2)/0.0225 = 30.8

step-by-step explanation:

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
