Question

The owners of a recreation area are filling a small pond with water. Let W be the total amount of water in the pond (in liters). Let T be the total number of minutes that water has been added. Suppose that w= 35T +300 gives W as a function of T during the next 70 minutes.Identify the correct description of the values in both the domain and range of the function. Then, for each, choose the most appropriate set of values.

Answer 1

Given:

`W=35T+300`

To find:

The domain and the range when t = 70 minutes.

Step-by-step explanation:

When t = 70, we get

`\begin{gathered} W=35(70)+300 \\ W=2750l \end{gathered}`

The ordered pair of the solution is,

`(70,2750)`

As the domain is the set of all input values, so the domain will be,

`[0,70]`

As the range is the set of all output values, so the range will be,

`[300,2750]`

Final answer:

The domain is,

`[0,70]`

The range is,

`[300,2750]`
