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:
the coordinates are (2,-7)
Step-by-step explanation:
its this bacause if you add all the vertices then subtract them you will get this
The answer to this question is A. 120°
Answer:
904.8 cm rounded (904.78 cm^3) to the nearest tenth.
Step-by-step explanation:
V= 904.8 cm rounded (904.78 cm^3) to the nearest tenth.
Step-by-step explanation:
The volume of a sphere is given as 4/3πr^3
There is only one variable, the radius, which we are given in the problem.
since the radius is 6 cm, we can plug that in to the formula
4/3π6^3
Put this into the calculator, and we see that the volume is
904.8 cm rounded (904.78 cm^3) to the nearest tenth.
Answer:
A four-sided plane rectilinear figure with opposite sides parallel.
To conclude, this would NOT be a parallelogram since the opposite sides aren't parallel.
Let me know if it's right.
