Hello!

The answer is z = 16..

Solve it like this..

#1) Regroup terms

-3 = -7+z/4 ---> -3 = z/4 - 7

#2) Add 7 to both sides.

-3 = z/4 - 7 ---> -3 + 7 = z/4

#3) Do the addition.

-3 + 7 = z/4 ---> 4 = z/4

#4) Multiply both sides by 4.

4 = z/4 ---> 4 * 4 = z.

#5) Do the multiplication.

4 * 4 = z ---> 16 = z

Hope this helps! ☺♥

suppose the population of a town is growing exponentially. the population was 4,636 in 2008 and grew to 5,508 in 2018. what is t

Sloan [31]

<h2>94.93</h2>

Step-by-step explanation:

The standard equation used to model a exponential growth is given by $f(t)=Ae^{Bt}$

Given two data points, which are both explicitly a function of time, it is easy to solve the two equations,

$4636=Ae^{2008B} ,5508=Ae^{2018B}$

Dividing the second equation by the first,

$\frac{5508}{4636}=\frac{Ae^{2018B} }{Ae^{2008B} }$

$e^{10B}=\frac{5508}{4636}$

$10B=ln(\frac{5508}{4636} )=0.17235$

$B=0.017235$

Substituting in first equation, $A=4.32645\textrm{x}10^{-12}$

Growth model : $f(t)=(4.3265\textrm{x}10^{-12} )e^{0.017235t}$

Growth rate= $ABe^{Bt}$ = $94.93$

∴Approximate growth rate as of 2018 = 95
