Question

The sales of a certain product after an initial release can be found by the equation s=12 sqrt (4t) + 10 , where s represents the total sales (in thousands) and t represents the time in weeks after release. Make a table of values, graph the function and use the graph to estimate the sales 12 weeks after release.

Check the picture below.

Answer 2

Explanation:

Given : The sales of a certain product after an initial release can be found by the equation
`s=12√(4t)+ 10`, where s represents the total sales (in thousands) and t represents the time in weeks after release.

To find : Make a table of values, graph the function and use the graph to estimate the sales 12 weeks after release ?

Solution :

The equation
`s=12√(4t)+ 10`

where, s represents the total sales (in thousands) and t represents the time in weeks after release.

We put t=1,2,3,.....,12 and create a table

t
`s=12√(4t)+ 10`
