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

Hello if im right your answer should be x

Answer:
if the height is h and the base is 2b
then we have:
½(2bh)=60→2bh=120
b²+h²=13²=169
so
(b+h)²=b²+h²+2bh=120+169=289
(b-h)²=b²+h²-2bh=169-120=49
so
b+h=17
|b-h|=7
so b can be 12 and h can be 5
or b can be 5 and h can be 12
which means the base is either 24cm or 10cm
