an initial investment of $9000 grows at an annual interest rate of 5% compounded continuously. how long will it take to double t

tino4ka555 [31]

Answer:

20 years

Step-by-step explanation:

9000/ 100= 900 = 10%

900/2= 450

450 x 2= 900

900 x 10= 9000

Now we multiply 10 by 2 because we doubled the value of our 450 into a 900 and now we get 20.

The earning of the salesperson is an illustration of a linear function.

The possible functions in the two scenarios are: $\mathbf{I(s) = 0.1s + 2500}$ and $\mathbf{I(s) = 0.05s + 2000}\\$

The function is given as:

$\mathbf{I(s) = 0.1s + 2000}$

When the base salary is increased, a possible function is:

$\mathbf{I(s) = 0.1s + 2500}$

This is so, because 2500 is greater than 2000

When the commission rate is decreased, a possible function is:

$\mathbf{I(s) = 0.05s + 2000}\\$

This is so, because 0.05 is less than 0.1

So, the possible functions in the two scenarios are:

$\mathbf{I(s) = 0.1s + 2500}$ and $\mathbf{I(s) = 0.05s + 2000}\\$

See attachment for the graphs of both functions

Mr.james runs a petting zoo. he records the number of visitors each week,v, t weeks, after opening the petting zoo. according to

melisa1 [442]

Answer:

$\large \boxed{\text{19 visitors/mo}}$

Step-by-step explanation:

The average rate of change is the change in the number of visitors divided by the change in the number of months.

1. Change in number of visitors

Change in visitors = 182 -125 = 57 visitors

2. Change in number of weeks

Change in time = 5 - 2 = 3 months

3. Average rate of change

$\begin{array}{rcl}\text{Average rate of change} &= &\dfrac{\text{change in visitors}}{\text{change in months}}\\\\&= &\dfrac{\text{57 visitors}}{\text{3 mo}}\\\\& = & \textbf{19 visitors/mo}\\\end{array}\\\text{The average rate of change is $\large \boxed{\textbf{19 visitors/mo}}$}$
