The population, P, of Johnstown over a period of t years since the town

IRISSAK [1]

Answer:

12 years

Step-by-step explanation:

Given that

P = 5,600 e^0.0591

Reaching amount = 11,200

time period = t

We need to find out the time period i.e. t

So,

11,200 = 5,600 e^0.0591t

2 = e^0.0591t

Now take the log on both the sides

ln2 = 0.0591t ln

t = ln2 ÷ 0.059

= 0.693147÷ 0.059

= 11.748

= 12 years

Answer:

$12a^3 +2a^2 +23a+18$

Step-by-step explanation:

$(3a+2)(4a^2-2a+9)$

we multiply 3a+2 inside the parenthesis to find the product

first multiply 3a inside second parenthesis

$12a^3 - 6a^2 +27a$

now multiply +2 inside second parenthesis

$8a^2 - 4a + 18$

Now we combine it

$12a^3 - 6a^2 +27a+8a^2-4a+18$

combine like terms

$12a^3 +2a^2 +23a+18$
