A population numbers 15,500 and grows at 3.75% per year. Write an exponential model for the growth of this population.

krek1111 [17]

Answer: $f(x)=15500(1.0375)^x$

Step-by-step explanation:

The exponential model for growth is given by :-

$f(x)=A(1+r)^x$ , where A = initial value , r = growth rate (in decimal), x = time (in years).

Given: A= 15,500 r= 3.75% = 0.0375

The exponential model for the growth of this population will be :

$f(x)=15500(1+0.0375)^x\\\\\Rightarrow\ f(x)=15500(1.0375)^x$

hence, the required model: $f(x)=15500(1.0375)^x$

s344n2d4d5 [400]

Step-by-step explanation:

$\dfrac{w}{3}6\qquad\text{divide both sides by 3}\\\\\dfrac{3w}{3}>\dfrac{6}{3}\\\\w>2\\\\$

$\text{If is}\ \bold{OR},\ \text{then}:\\\\w2\Rightarrow w\in\mathbb{R}\ /\text{any real number/}\\\\\text{If there is a mistake, and it should be}\ \bold{AND},\ \text{then}:\\\\w2\Rightarrow 2$
