Answer:
x = 250 units
Step-by-step explanation:
We can easily solve this problem by using a graphing calculator or any plotting tool.
We must find the minimum point in the graph. This corresponds to the number of machines that produce the minimum cost.
The equation is
C (x) = 1.2x^2 -600x + 89,966
Please see attached image below
By producing x = 250 units, we obtain the minimum cost
Answer:
Ryan's maximum time to complete a puzzle is 5 hours
Ryan's minimum time to complete a puzzle is 1 hour
Step-by-step explanation:
<u><em>The complete question is</em></u>
On average, Ryan can finish a puzzle in 3 hours but, depending on the difficulty of the puzzle, his time can vary from the average by 2 hours.
Which absolute value equation can be used to calculate Ryan's maximum and minimum time to complete a puzzle?
Let x represent the maximum and minimum time
we know that
The absolute value of the difference between x and the average must be equal to 2
so
Solve the absolute value
First case (positive case)
Second case (negative case)
Multiply by -1 both sides
therefore
Ryan's maximum time to complete a puzzle is 5 hours
Ryan's minimum time to complete a puzzle is 1 hour
Answer:
Step-by-step explanation:
P=(2,-3)
Q=(a,a²-2a-3)
Proof:
y'=(x²-2x-3)'=2x-2
y'(2)=2*2-2=2
