4 Find a formula for the exponential function passing through the points (-2, 4/9) and (3, 108)​
NemiM [27]

9514 1404 393

Answer:

  f(x) = 4·3^x

Step-by-step explanation:

We assume the function will be of the form ...

  f(x) = a·b^x

Substituting the given values, we can find 'a' and 'b'.

  4/9 = a·b^(-2)

  108 = a·b^3

Dividing the second equation by the first gives ...

  108/(4/9) = b^(3 -(-2))

  243 = b^5

  b = 3 . . . . . . 5th root

Using the second equation, we can find 'a':

  108 = a·3^3 = 27a

  a = 108/27 = 4

The formula for the exponential function is ...

  f(x) = 4·3^x

Dad bought $200,000 of term life insurance at the rate of $5.40 per thousand-dollar unit. How much is the annual premium?
irina1246 [14]

Answer:

It is clear that the annual premium = $1080

Explanation:

Given:

As the total term amount for life insurance is given in the question which is $200,000

rate per $1000 unit = $5.40

<em><u>Simple Calculation Procedure to get the annual premium: </u></em>

First step:  

Let’s assume $1000 is one unit and the mentioned rate per $1000 unit is $5.40. Now, all you need is to find total number of $1000 units in total term insurance amount ($200,000).  

So,  

divide $200,000 by $1000 to establish the total number of  

1000 units in $200,000 = $200,000/$1000 = 200  

Second step:

As 200 is found to be the total number of $1000 units in $200,000.

So, just multiply 200 with $5.40 to ultimately find the annual premium

            i.e. $5.40 × 200 = $1080

Hence, it is clear that the annual premium = $1080
