ANSWER-
4
EXPLANATION-
12/3 = 4
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
Answer:
x=35
Step-by-step explanation:
Since these are straight lines, you simply reflect the 35 degrees over the other side because this is a vertical angle.
x=35
Answer:
Perimeter = 31.4in
Area = 78.5in^2
Step-by-step explanation:
Perimeter -
2 x 5 x 3.14 = 10 x 3.14 = 31.4in
Area -
5 x 5 x 3.14 = 25 x 3.14 = 78.5in^2
