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
Salut! Alecu ar citi in 12 zile 14 x 12 = 168 de pagini (atatea pagini are cartea); O saptamana are 7 zile, asa ca 168 ÷ 7 = 24 de pagini trebuie sa citeasca zilnic Alecu ca sa inapoieze cartea la sfarsitul celor 7 zile; Succes!
I have these same questions but the way i solved them i did
A: 1/3 x 3.14 x 2*2 x 8 = 32/3 = 2000 divided by 32 = 63 scoops The formula is 1/3 x 3.14 x r*2 x h B: 1/3 x 3.14 x 8*2 x 8 = 128/3 = 2000 divided by 128 = 16 scoops
