Answer:
The minimum unit cost is 5377
Step-by-step explanation:
Note that we have a cudratic function of negative principal coefficient.
The minimum value reached by this function is found in its vertex.
For a quadratic function of the form
the x coordinate of the vertex is given by the following expression
In this case the function is:
So:
Then the x coordinate of the vertex is:
So the minimum unit cost is:
Given the polynomial equation x^3 -6x = 3x^2 – 8. Which can be simplified into (x^3) -3(x^2) -6x +8 = 0. The roots of the given equation are x = -2, x = 1 and x = 4. The order of equation also represents the number of roots of the equation given. Since the highest exponent is 3, there also 3 roots. So the answer is D. 2 –2, 1, 4
Answer:
33%
Step-by-step explanation:
In 2003, there were 78.9 thousand jobs in the industry and it increases annually by 2.65 thousand jobs from 2003 to 2013.
Hence, from 2003 to 2013, i.e. 10 years the jobs have increased by (2.65×10) = 26.5 thousand.
Therefore, the percent increase in jobs in the industry from 2003 to 2013 is given by 
% ≈ 33%. (Answer)
The quadratic formula is 
So the solution for k is 16.

Answer:
x = 109
Step-by-step explanation:
In pentagons, the total degrees for the interior angles is always 540 degrees.
540 = 91 + 160 + 100 + 80 + x
540 = 431 + x
109 = x
