Answer:
90 engines must be made to minimize the unit cost.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:

It's vertex is the point 
In which


Where

If a>0, the minimum value of the function will happen for 
C(x)=x²-180x+20,482
This means that 
How many engines must be made to minimize the unit cost?
x value of the vertex. So

90 engines must be made to minimize the unit cost.

Answer: Hello some part of your question is missing below is the missing part 
Missing question:  Find the probability that the Smith family had at least 6 girls?
answer : 0.1406
Step-by-step explanation:
Number of children = 8 
probability of a child being a girl ( success ) = 0.5  ( 
P( boy ) ( q ) = 1 - 0.5 = 0.5 
P( at least 6 girls ) = p(k = 6 ) + p(k = 7 ) 
                               = 0.109375 + 0.03125 ≈ 0.1406
