domain and range are both all real numbers :)
Answer:
a i think
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
Answer: 294cm
Step-by-step explanation:
The volume of a oblique cylinder is given by:
Volume= πr^2h
where
π = 3.14
r = radius
h = height
Radius= diameter/2 = 6/2 = 3
We have all the values, so we put it in the formulae so we can get the answer.
Volume= πr^2h
= 3.14 × 3 × 3 × (0.4 × 26)
= 294cm
