The population of Jacksonville in 2018 is estimated to be 19,000 people with an annual rate of increase of 3.4%. Which equation

Umnica [9.8K]

Answer:

$P=19,000(1.034)^{t}$

Step-by-step explanation:

Let

P-------> the population of Jacksonville

t----> the number of years since 2018

we know that

The equation that models the population of Jacksonville in t years is

$P=19,000(1+r)^{t}$

we have

$r=3.4\%=3.4/100=0.034$

substitute

$P=19,000(1+0.034)^{t}$

$P=19,000(1.034)^{t}$

Find the solution set. (x+7)(x+7)=0

levacccp [35]

For this case we must find the solution of the following expression:

$(x + 7) (x + 7) = 0$

If we isolate a term and we equate to zero, we have:

$x + 7 = 0$

Subtracting 7 on both sides of the equation we have:

$x + 7-7 = 0-7\\x = -7$

Thus, the solution of the expression is given by:

$x = -7$

ANswer:

$x = -7$
