Answer:
Step-by-step explanation:
= 6.5%
Answer:
thirty
Step-by-step explanation:
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
Use a number line and plot it with zero in the middle and the positive numbers on the right and the negative numbers on the left
the farther to the right a number is, the bigger it is
the farther to the left a number is, the smaller it is
