That's easy, you just multiply.

For example, when its 3 * 1 = 3, but here there are letters/variables that hold number which you don't know and that's the reason you write letter with it showing you are multiply it instead of writing  3 * a, simple for would be 3a.


a) 3a

b) 3a

c) 4x

d) 3pq

e) 7fe

f) zwy

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

You are trying to isolate x, so you would first subtract the y and get ax-bx= z-y
then you would divide by a-b
giving you A as the answer
