a.
To write a function that represents perimeter of the
a.
Answer to Problem 39E
Explanation of Solution
Given information :
  
Third side of the triangle is given as h .
Hence the function for perimeter is,
  
b.
To determine the independent and dependent variables.
b.
Answer to Problem 39E
h is independent whereas
Explanation of Solution
Here the perimeter of the triangle depends on the third side of the triangle that is h .
Hence we can say that
c.
To determine the range and domain of the function.
c.
Answer to Problem 39E
The domain is (3, 23)
The range of the function is (26, 46)
Explanation of Solution
Given information :
  
We know that the sum of two sides of a triangle is always greater than the third side.
Hence we get,
  
Hence the domain is (3, 23)
Now put the value of h in the perimeter function we get,
  
Therefore the range of the function is (26, 46)
