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

Solve for e. 9e^2f=49<br> e=±√7f/3<br> e=±7√f/3<br> e=±7√f/3f<br> e=±√7f/3f
Vesnalui [34]
Divide by the coefficient of e^2, then take the square root.
  e^2 = 49/(9f)
  e = ±7/(3√f) = ±(7√f)/(3f)

The 3rd selection is appropriate:
  e=±(7√f)/(3f)


______
When written in plain text (not typeset), any denominator containing arithmetic must be enclosed in parentheses. When the expression is typeset, the surd and the division bar do the grouping for you.
  e=\pm \dfrac{7\sqrt{f}}{3f}

What is the answer to the question -4•-10
Elis [28]
The answer is 40.
Because when you multiply 2 numbers, it becomes a positive number.(-4x10 or -2x3)
But if it were only one negative and positive then it would be negative because the answer is negative when you multiply by one negative number.
