Questions:
A clothing manufacturer uses the model a = √(f + 4) - √(36 - f) to estimate the amount of fabric to order from a mill. In the formula, a is the number of apparel items (in hundreds) and f is the number of units of fabric needed. If 400 apparel items will be manufactured , how many units of fabric should be ordered?
Answer:
32 units of fabrics
Step-by-step explanation:
Given

Find f when a = 4
Substitute 4 for a
Rewrite as:
Square both sides
Collect Like Terms
Divide through by 2
Square both sides
Collect like terms
Factorize
or 
f can not be 0 because some units must be ordered.
So, f = 32
Answer:
54 km
Step-by-step explanation:
The distance she covers would be equal to twice the perimeter of the park which is in the shape of a rectangle
perimeter of a rectangle = 2 x (length x width)
length = 4.5
width = 2 x 4.5 = 9
2 x (4.5 + 9) = 27km
In one walk, she covers a distance of 27km. In two walks, she covers a total distance of 27km x 2 = 54km
