Question

The function we need to use answer this is h(r)= √4-r

Answer 1

Given:

`\begin{gathered} h(r)=√(4)-r............(1) \\ 3h(r)+2=4..............(2) \end{gathered}`

To find:

The value of r.

Step-by-step explanation:

Using function (1) in (2),

`\begin{gathered} 3(√(4)-r)+2=4 \\ 3(2-r)=4-2 \\ 6-3r=2 \\ -3r=-4 \\ r=(4)/(3) \end{gathered}`

Therefore, the value of r is,

`(4)/(3)`

Final answer:

The value of r is,

`(4)/(3)`
