The population growth of a community is modeled by the equation P (x) = 15,5580.4x + 1, where P (x) is population and x is time in years beginning with x = 0. When does the population double? Round to the nearest tenth of a year.

The population will be double in 0.5 years.

Step-by-step explanation:

The population growth of a community is modeled by the equation , where P (x) is population and x is time in years beginning with x = 0.

Therefore, the population at x = 0 will be =

If the population becomes double then we can write the equation as

⇒

⇒

⇒ 2(x + 1) = 3 {Comparing the power terms}

⇒ x + 1 = 1.5

⇒ x = 0.5 years.

Therefore, the population will be double in 0.5 years. (Answer)

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
