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
