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]

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

It would be either A or D because it says that john has 3 rows and does not say of how many stickers...but Raj have 36 stickers and Tajika has 36 stickers and Sue Lee has 40 so it would either A or D
