Answer:
I think the answer is$12 - $3 = $9
the amount u need is $9 to have the complete amount u need to purchase the ticket
Answer: x=3 isn't a function because multiple different inputs have the same outputs
Step-by-step explanation:
I dont know how to answer the first question since the dropdown is shown
The cost function is
c = 0.000015x² - 0.03x + 35
where x = number of tires.
To find the value of x that minimizes cost, the derivative of c with respect to x should be zero. Therefore
0.000015*2x - 0.03 = 0
0.00003x = 0.03
x = 1000
Note:
The second derivative of c with respect to x is positive (= 0.00003), so the value for x will yield the minimum value.
The minimum cost is
Cmin = 0.000015*1000² - 0.03*1000 + 35
= 20
Answer:
Number of tires = 1000
Minimum cost = 20
