Answer:

Step-by-step explanation:

The correct factoring can be found by looking at the first exponent in the second set of parentheses.

The factorization of ...

(a^3 -b^3)

is ...

(a -b)(a^2 +ab +b^2)

Here, you have a=6x^4 and b=4, so the first term in the second parentheses is ...

a^2 = (6x^4)^2 = 6^2·x^(4·2) = 36x^8 . . . . matches the 3rd choice

A village experienced 2% population growth, compounded continuously, each year for 10 years. At the end of the 10 years, the pop

pantera1 [17]

Answer:

The initial population at the beginning of the 10 years was 129.

Step-by-step explanation:

The population of the village may be modeled by the following function.

$P(t) = P_{0}e^{rt}$

In which P is the population after t hours, $P_{0}$ is the initial population and r is the growth rate, in decimal.

In this problem, we have that:

$P(10) = 158, r = 0.02$ .

$158 = P_{0}e^{0.02*10}$

$P_{0} = 158*e^{-0.2}$

$P_{0} = 129$

The initial population at the beginning of the 10 years was 129.
