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
Required
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
1) -13 = -4a - 2b + c
-13 = -2(2a + b) + c
2) 3 = 4a + 2b +c
3 = 2(2a + b) + c
3) 5 = 16a + 4b + c
5 = 4(4a + b) + c

The answer is B hope this helps
Answer:
Step-by-step explanation:
This first step is to take the square root of the minus which is understood to be - 1
sqrt(-1) = i
So far what you have is
sqrt(-98) = i*sqrt(98)
sqrt(98) is just found the ordinary way
sqrt(98) = sqrt(7*7*2)
sqrt(7*7*2) = 7*sqrt(2)
Answer: 7 * i * sqrt(2) = i7*sqrt(2)

Answer:
a)There are 14 teachers in Ryan's sample, and 362 teachers in the population.
Step-by-step explanation:
<u> Population:-</u>
<em>The totality of observations with which we are concerned, whether this number be finite or infinite is called population.</em>
<em>Given data population is 376 teachers at a university were female'</em>
<u><em>Sample:-</em></u>
A sample is a subset of a Population
sample of given data = 14teachers
The percentage of 376 teachers at a university were female, Ryan randomly selected 14 teachers.
<em />
<em> = 3.72%</em>
